The best external drive depends on what you value most. Choose the WD My Passport if you want an affordable, portable hard disk for everyday backups and extra capacity. Choose the Seagate Expansion Desktop if you need the most storage at a desk. For frequent travel, active photo or video work, fast transfers, or better resistance to drops, choose the Samsung T7 Shield or a correctly identified SanDisk Extreme Portable SSD.
One terminology point matters: “external hard drive” is often used as an umbrella term for both mechanical hard disk drives (HDDs) and solid-state drives (SSDs). HDDs generally offer much more capacity per dollar; SSDs are smaller, faster, quieter, and better suited to travel and active work. This guide separates the two rather than pretending there is one universal winner.
Testing note: These are editorial recommendations based on independent external-storage testing described by Tom’s Hardware, including real-world file-transfer work, combined with current manufacturer specifications. We have not personally tested or drop-tested these products, so advertised speeds are identified as manufacturer ratings rather than guaranteed copy performance.
Best external drives at a glance
| Best for | Pick | Drive type | Why it stands out | Main limitation |
|---|---|---|---|---|
| Most people needing portable capacity | WD My Passport | Portable HDD | Good balance of capacity, compatibility, bundled backup and password tools, and warranty coverage | Much slower and less shock-resistant than an SSD |
| Lowest-cost simple portable storage | WD Elements Portable | Portable HDD | Simple, compact bulk storage without the extra management features | Exact features and warranty depend on the model and region |
| Maximum desk-based capacity | Seagate Expansion Desktop | Desktop HDD | Current documentation covers capacities from 4TB through 28TB | Larger enclosure, external power, and poor portability |
| Rugged portable SSD | Samsung T7 Shield | Portable SSD | Fast USB 3.2 Gen 2 interface, IP65 rating, drop resistance, and hardware encryption | Costs more per terabyte than an HDD |
| Rugged SSD alternative | SanDisk Extreme Portable SSD | Portable SSD | Compact, rugged design with a five-year US warranty on the documented generation | Several generations exist, with substantially different advertised speeds |
HDD or SSD: which kind of external drive should you buy?
For a large photo archive, game library, media collection, or backup destination that normally stays at home, an external HDD is usually the sensible value choice. Its mechanical platters and read/write heads make it slower and more vulnerable to shock while operating, but the cost-per-terabyte is generally lower.
An external SSD stores data in flash memory. It has no moving parts, is typically much faster for large transfers and application work, and is better suited to being carried between locations. That does not make an SSD a complete backup strategy or automatically guarantee longer archival life. SSDs still fail, can be lost, and can be damaged by heat, mishandling, controller faults, or accidental deletion.

| Consideration | Portable or desktop HDD | Portable SSD |
|---|---|---|
| Capacity per dollar | Usually better | Usually worse, especially at high capacities |
| Large-file transfers | Slower and workload-dependent | Much faster when the computer, port, and cable support the required USB standard |
| Small files and active projects | Less responsive | Better suited to editing, project files, and working directly from the drive |
| Travel and movement | Needs more care, particularly while operating | Smaller and more resistant to movement and ordinary bumps |
| Noise and power | May produce motor and seek noise; desktop models need a power brick | Silent and generally easier to power from a laptop |
| Best role | Secondary storage, archives, and local backups | Active work, travel, fast transfers, and portable working storage |
Tom’s Hardware’s storage guidance broadly reflects this division: modern computers should generally use SSDs for operating-system or boot-drive duties, while HDDs remain useful as secondary storage. An external HDD can hold a backup of a computer, but it is usually a poor substitute for the computer’s internal SSD when responsiveness matters.
Best portable HDD for most people: WD My Passport
The WD My Passport portable hard drive is the best general-purpose choice when you want inexpensive storage that can travel with a laptop. WD’s current documentation lists 2TB, 4TB, 5TB, and 6TB capacities, giving buyers useful choices for documents, photos, schoolwork, media, and secondary backups.
Free tools Windows power users keep installed
One-click scans. No signup required.
It uses USB-C with USB 3.2 Gen 1 connectivity and remains compatible with USB 2.0. The drive is formatted as exFAT out of the box, which makes it practical for exchanging ordinary files between Windows, macOS, and ChromeOS without immediately reformatting it. WD also lists password-protection and backup software, along with a three-year worldwide warranty.
Why it is the default recommendation
- Broad out-of-box compatibility: exFAT is convenient for users who move files between Windows and Mac computers.
- Useful capacity range: 2TB through 6TB covers most portable HDD use cases without moving to a bulky desktop enclosure.
- More than bare storage: The bundled password-protection and backup tools are useful for people who do not want to assemble a backup workflow from separate utilities.
- Reasonable support coverage: WD documents a three-year worldwide warranty for the current product family.
The trade-off is speed. USB 3.2 Gen 1 describes the interface, not a guaranteed sustained transfer rate. The actual result depends on the mechanical disk, file sizes, computer, cable, remaining free space, and workload. Expect the My Passport to be suitable for backups and file storage, not equivalent to a modern portable SSD.
Best inexpensive portable HDD: WD Elements Portable
Choose WD Elements Portable when your priority is a simple, usually lower-cost portable hard disk and you do not need My Passport’s bundled password-protection or management features. It is a sensible choice for a secondary photo archive, downloaded media, school files, or a second local copy of data.
Elements is best understood as a product family rather than one completely uniform specification. Confirm the exact capacity, interface, warranty, included software, and formatting in the listing you are about to buy. Seagate Expansion Portable is another reasonable alternative in this category, but Seagate’s own support documentation shows that specifications, warranty, and included features vary by model and region. Do not assume that every listing under the same family name has identical terms.
Buy a portable HDD in this category if you will mostly connect it for scheduled backups or occasional file access. Pay more for a portable SSD if you regularly edit from the drive, carry it in a crowded bag, or transfer large projects several times a day.
Best high-capacity desktop drive: Seagate Expansion Desktop
The Seagate Expansion Desktop is the better answer when portability is unimportant and capacity is the priority. Seagate’s current official documentation lists models from 4TB through 28TB, including 24TB, 26TB, and 28TB versions. That makes this family a strong fit for a desk-bound photo library, video archive, game collection, or local backup target.
Desktop external HDDs are physically larger than portable models and typically require an external power adapter. Seagate’s listed high-capacity models use USB 3.0 connectivity and carry a one-year limited warranty according to the cited documentation. Check the exact listing before purchase because capacity, warranty terms, and regional availability can change.
Rank #2
- Solid state performance with up to 800MB/s read speeds in a portable drive. (Based on internal testing; performance may be lower depending on host device, interface, usage conditions and other factors. 1MB=1,000,000 bytes.)
- Back up your content and memories on a storage solution that fits seamlessly into your mobile lifestyle.
- Take it with you on your adventures—up to two-meter drop protection means this durable drive can take a beating. (Based on internal testing.)
- Secure it to your belt loop or backpack for extra peace of mind thanks to the tough rubber hook.
- From Sandisk, a brand professional photographers trust to take on assignments.
This is not the drive to toss into a travel bag. Keep it on a stable, ventilated desk, avoid disconnecting it while it is writing, and use the operating system’s eject command before unplugging it. For a desktop archive, the extra capacity is usually more valuable than the portability and speed premium of an SSD.

The Samsung T7 Shield is the strongest pick for people who travel with data, move large photo or video files, or work directly from an external drive. It is available in 1TB, 2TB, and 4TB capacities and uses USB 3.2 Gen 2 connectivity.
Samsung rates it for sequential read speeds of up to 1,050 MB/s and sequential write speeds of up to 1,000 MB/s. Those are manufacturer-rated maximums, not a promise that every computer will copy files at those speeds. A slower USB port, unsuitable cable, source drive, small-file workload, nearly full SSD, or thermal throttling can produce a very different result.
The T7 Shield’s durability features are more meaningful than a generic “rugged” label:
- IP65 water-and-dust resistance: This is resistance under the specified test conditions, not proof that the drive is waterproof or safe to submerge.
- Up to three-meter drop resistance: This is a rated limit, not permission to treat the drive carelessly or assume every drop will be harmless.
- AES-256 hardware encryption: Useful for sensitive work files, provided the security feature is configured and the password is kept safe.
- Three-year limited warranty: The warranty covers the product under its terms; it does not replace a second copy of the data.
Its main disadvantage is price per terabyte. A 4TB T7 Shield can be an excellent working drive, but a large home archive will generally cost less on one or more HDDs. The sensible arrangement for many photographers and videographers is a fast SSD for current projects plus separate HDD storage for backups and completed work.
Rugged SSD alternative: SanDisk Extreme Portable SSD
The SanDisk Extreme Portable SSD is a strong alternative to the T7 Shield, but buyers must identify the generation before comparing performance. SanDisk’s documentation for the earlier USB 3.2 Gen 2 generation lists capacities from 500GB through 4TB, up to 1,050 MB/s read and 1,000 MB/s write speeds, IP65 water-and-dust resistance, shock resistance, and a five-year limited warranty in the United States.
SanDisk’s newer V3 product page advertises up to 2,000 MB/s transfer speeds for 1TB–4TB models. That claim belongs to the V3 models and should not be applied to every SanDisk Extreme listing. Before buying, check the exact SKU, capacity, generation, interface, and warranty in the retailer’s listing and the manufacturer’s documentation.
Rank #3
- Easily store and access 2TB to content on the go with the Seagate Portable Drive, a USB external hard drive
- Designed to work with Windows or Mac computers, this external hard drive makes backup a snap just drag and drop
- To get set up, connect the portable hard drive to a computer for automatic recognition no software required
- This USB drive provides plug and play simplicity with the included 18 inch USB 3.0 cable
- The available storage capacity may vary.
As with Samsung, the IP65 label means water-and-dust resistance under a defined rating; it does not mean waterproof. The Extreme is a good fit for mobile creative work and travel, particularly when its compact design and warranty terms are more attractive than the Samsung alternative. It is not automatically a better value for bulk storage.
How these recommendations were evaluated
“Based on real-world testing” should mean more than copying the sequential-read number from a product box. Tom’s Hardware says its external-storage recommendations come from drives it has tested, and its more recent storage methodology describes using DiskBench and a custom 50GB dataset for practical file-transfer testing.
A useful external-drive evaluation should consider:
- Sustained large-file copying: This reflects moving video, disk images, large photo exports, and other continuous workloads.
- Small-file handling: Thousands of small documents or project assets can behave very differently from one large file.
- Temperature and throttling: Portable SSDs can slow down after sustained heavy work if heat builds up.
- Noise: HDD motors and head movement can be audible; SSDs are silent.
- Portability: Size, weight, cable flexibility, and resistance to ordinary travel hazards matter more for a drive that leaves the desk.
- Setup and compatibility: Formatting, encryption tools, USB standards, and whether the drive needs a power brick affect the ownership experience.
- Warranty and model clarity: A product family may contain several capacities, generations, and regional variants.
Sequential benchmarks can resemble the manufacturer’s best-case specification. Actual copy performance depends on the host computer, USB standard, cable, file mix, drive capacity, remaining free space, and thermal conditions. A benchmark is useful for comparing controlled results; it is not a guarantee for your laptop or workflow.
Choose by task
For laptop backups and ordinary files
Buy the WD My Passport if you want a portable HDD with broad compatibility and bundled management features. WD Elements Portable is the value-oriented alternative when simple storage is enough.
For a large home archive
Choose the Seagate Expansion Desktop when the drive will remain on a desk and you need up to the high capacities documented for that family. If the data matters, do not put the only copy on the desktop drive.
Recommended Free Tools
For photo and video editing
Use the Samsung T7 Shield or an appropriately identified SanDisk Extreme SSD for current projects and active editing. Confirm that the computer has a sufficiently fast USB port and that the cable supports the connection you intend to use. Keep a separate backup because an SSD’s speed does not protect against deletion, theft, or hardware failure.
Rank #4
- NEARLY 2X FASTER THAN OUR PREVIOUS GENERATION(8) – move 1,000 high-res photos in under 60 seconds(6) with up to 2000MB/s transfer speeds(2).
- IP65 RATING AND UP TO 3M DROP PROTECTION(3) – protects against spills and drops.
- POCKET-SIZED – fits easily in pockets and small bags.
- SPACE TO OWN YOUR AI CONTENT – speed and capacity to download your high-res clips and photo edits.
- 256-BIT AES ENCRYPTION(4) – helps keep private files secure with password protection.
For frequent travel
A portable SSD is usually the better choice because it is compact, silent, and less vulnerable to movement than a mechanical drive. The Samsung T7 Shield is the simpler recommendation when you want clearly documented IP65 protection, drop resistance, and hardware encryption. The SanDisk Extreme is also compelling, but verify whether it is the earlier USB 3.2 model or the newer V3.
For sensitive files
Use hardware encryption on a supported SSD such as the T7 Shield, or configure appropriate software encryption on the computer or drive. Password protection is only useful if you remember the password and retain another secure copy of important data.
Mac and Windows compatibility: format the drive deliberately
A drive advertised as compatible with Windows and macOS is often formatted as exFAT. That is convenient for ordinary files shared between the two platforms, and the current WD My Passport documentation specifically lists exFAT compatibility with Windows, macOS, and ChromeOS.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
A dedicated Mac backup can use a Mac-selected format instead. Apple documents Time Machine backups to external USB or Thunderbolt storage and recommends a backup disk with at least twice the capacity of the Mac’s internal storage. On current macOS, the setup path is generally Apple menu > System Settings > General > Time Machine; older macOS versions use System Preferences > Time Machine.
Apple also documents direct-connected external storage and compatible network-attached storage using SMB. If you need both Time Machine and ordinary file storage on one physical device, macOS can use separate APFS volumes. That arrangement is convenient, but it is not protection against the physical drive failing: both volumes disappear if that one device dies.
Before reformatting
- Copy any existing files from the drive to another location.
- Open the disk utility for your operating system. On Mac, use Applications > Utilities > Disk Utility.
- Select the correct physical drive, choose Erase, and select the format appropriate to the job: exFAT for cross-platform file exchange, or a Mac-compatible format for a dedicated Mac workflow.
- On Mac, use GUID Partition Map when creating a modern boot or data volume unless a specific legacy requirement says otherwise.
- Verify the drive appears correctly, then copy a noncritical test file before moving the only copy of anything important.
Warning: Formatting and erasing can destroy existing data. Confirm the drive name and backup location before clicking Erase.
Cables, ports, power, and travel accessories
USB labels are a common source of disappointing results. A USB-C connector describes the shape of the plug, not necessarily the speed of the connection. A USB-C port can support different USB generations, and an older computer or cable can limit a fast SSD. Check the computer’s port specification and use a compatible USB-C/USB-A data cable when moving between newer USB-C laptops and older USB-A computers.
Portable HDDs and SSDs are normally designed for direct connection, but a low-power laptop or crowded setup may need a powered USB hub for external hard drives. Desktop HDDs are different: they normally use their supplied external power adapter and should not be treated as bus-powered travel drives.
If a portable drive will live in a backpack, an external hard drive travel case can reduce scratches, cable strain, and accidental impacts. A case does not make an HDD safe to operate while being shaken, and it does not change an SSD’s water-resistance rating.

Backblaze’s 2025 drive-reliability report analyzed 344,196 qualifying hard drives across 30 models over the full period from January 1 through December 31, 2025. Large fleet data can provide useful context about how failure rates vary by model and age, but it should not be turned into a direct ranking of consumer external-drive products.
Best Value
- Easily store and access 5TB of content on the go with the Seagate portable drive, a USB external hard Drive
- Designed to work with Windows or Mac computers, this external hard drive makes backup a snap just drag and drop
- To get set up, connect the portable hard drive to a computer for automatic recognition software required
- This USB drive provides plug and play simplicity with the included 18 inch USB 3.0 cable
- The available storage capacity may vary.
Data-center drives operate in a different environment from consumer external drives. The internal mechanism may differ, the enclosure may use different cooling, and data-center systems benefit from redundancy, monitoring, and replacement procedures. A Backblaze fleet failure rate is therefore not a promise about a particular portable enclosure bought for a laptop.
The Tool Desk
Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →The practical lesson is more important than the ranking: drives can fail, and reliability changes with model, age, handling, ventilation, and operating conditions. Backblaze recommends regular backups, proper ventilation, careful handling, and monitoring SMART data where available.
A safer minimum arrangement
- Keep the working files on the computer or primary storage.
- Maintain a separate local copy on an external HDD or SSD.
- Keep at least one additional copy, preferably in another physical location or with a reputable cloud backup or off-site backup service.
- Test that important files can actually be opened from the backup.
- Encrypt sensitive data and protect the passwords or recovery keys.
Two copies on separate volumes of the same physical external drive do not count as protection from that drive’s failure. Likewise, a drive sitting beside the computer is vulnerable to theft, fire, water damage, and power incidents affecting both devices.
Common buying mistakes
- Buying by the speed number alone: A rated 1,050 MB/s or 2,000 MB/s figure is a best-case sequential specification, not a guaranteed everyday copy speed.
- Confusing connector type with performance: USB-C does not by itself guarantee USB 3.2 Gen 2 or faster operation.
- Using a portable HDD for active editing: It may work, but an SSD is generally better for frequent large transfers and responsive project access.
- Using a desktop HDD as a travel drive: Expansion Desktop-class drives need desk space and external power.
- Comparing different SanDisk generations: The earlier Extreme and newer Extreme V3 do not have the same advertised performance.
- Assuming IP65 means waterproof: IP65 indicates resistance under specified conditions, not safe submersion.
- Reformatting without a second copy: Erase operations can remove everything on the drive.
- Treating encryption or password protection as backup: Security protects access; it does not create another copy.
- Trusting a family name instead of the exact listing: Capacity, warranty, interface, included software, and regional terms can vary.
Final buying checklist
- Decide whether the drive will be portable, desk-bound, or used for active work.
- Choose HDD for lower-cost capacity and SSD for speed, travel, and working directly from the drive.
- Check the exact capacity and model number, not just the family name.
- Confirm the computer’s USB port, cable, and power requirements.
- Choose exFAT for ordinary Windows/Mac file sharing, or a Mac-oriented format for a dedicated Time Machine setup.
- Copy existing files elsewhere before formatting.
- Check warranty terms for the exact capacity and region.
- Plan a second local or off-site copy before storing irreplaceable data.
Frequently Asked Questions
Is an external SSD safer than an external HDD?
An SSD is generally better for travel and active use because it has no moving parts and is more resistant to movement than a mechanical HDD. It is not automatically safer for long-term storage: SSDs can fail, and neither type protects against accidental deletion, theft, or a single-device failure. Keep another copy of important data.
Can I use one external drive for both Windows and Mac?
Yes, exFAT is a practical format for ordinary files shared between Windows and macOS, and the current WD My Passport documentation lists exFAT compatibility with both platforms. Reformatting erases the drive, so copy existing data elsewhere first. A dedicated Mac Time Machine setup may instead use a Mac-compatible format or separate APFS volumes.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsHow large should a Time Machine drive be?
Apple recommends a backup disk with at least twice the capacity of the Mac’s internal storage. More capacity allows Time Machine to retain a longer history of older file versions.
Can I use an external HDD as a boot drive?
It is possible in some operating-system configurations, but an HDD is generally a poor choice for boot-drive duties because of its slower responsiveness. A portable SSD is better suited to an active operating system or frequently used applications, provided the computer and operating system support that setup.
Do advertised SSD speeds apply to every computer?
No. The Samsung T7 Shield’s 1,050/1,000 MB/s figures and the SanDisk Extreme family’s advertised speeds are maximum sequential specifications. The host USB standard, cable, file mix, source storage, available free space, and temperature can all reduce actual performance.
The Bottom Line
For most people, buy the WD My Passport when you want affordable portable capacity, the Seagate Expansion Desktop when you want the most desk-based storage, and the Samsung T7 Shield when speed, travel, and ruggedness matter. The SanDisk Extreme Portable SSD is a good alternative only after confirming the exact generation. Whichever drive you choose, keep a second copy of important data—preferably off-site—because an external drive is a backup destination, not a backup strategy by itself.
