Choose an external SSD by matching its usable capacity to the files and versions you plan to keep, checking that your PC and cable support its interface, and confirming that your backup software can use the drive’s format. Then decide whether portability, ruggedness, or encryption matters for how you store it. An SSD is only one part of a backup plan: Windows File History can save personal files to an external drive, while Windows Backup uses OneDrive and a Recovery Drive is for Windows recovery rather than personal files.
1. Decide what kind of backup you need
Before comparing SSDs, decide what you need to restore. A drive used for copies of documents and photos is not automatically a complete Windows system-recovery solution.
- File History: Microsoft describes File History as a way to periodically save copies of personal files to an external drive or network location and browse earlier versions. It is a relevant option for a local file backup.
- Windows Backup: Microsoft’s Windows Backup overview centers on backing up selected folders and settings through OneDrive, with a Microsoft account sign-in. It is a cloud workflow, not a copy stored on the external SSD.
- Recovery Drive: This creates Windows recovery media, but Microsoft states, “The Recovery Drive doesn’t include your personal files.” It does not replace a personal-file backup.
For a full system image, bare-metal recovery, or third-party backup application, check that application’s current requirements and supported restore process. The Microsoft guidance cited here does not certify every SSD for every such workflow. Microsoft’s Windows backup and recovery overview explains the distinctions; its File History instructions cover the external-drive option.
2. Size the SSD for your data and retention
Start with the amount of data you intend to back up, not just the advertised size of the PC’s internal drive. A PC may have substantial free space, or its drive may include applications and system files that your chosen file-backup workflow does not copy.

- Estimate the size of the files the backup software will include.
- Account for retained versions or multiple backup sets. File History can preserve earlier versions, which use space as they accumulate.
- Allow for expected growth and leave spare capacity so the drive is not immediately full.
- Compare that working estimate with the SSD capacities actually offered for the exact model and region.
There is no universal multiplier in the Microsoft guidance reviewed here. Buying a drive twice the size of the PC’s internal drive is not a dependable rule: the right capacity depends on what is included, how many versions are retained, and how quickly the data grows.
3. Match the interface to your PC and cable
An SSD’s advertised interface and speed do not guarantee that your PC will transfer data at that rate. The port, cable, host support, and drive all affect practical performance. Check the PC’s specifications and the cable supplied with the SSD before paying extra for a faster interface.

- 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.
- Identify the USB standard supported by the port you will use; a connector’s shape alone does not tell you its speed.
- Confirm that the SSD includes a cable that fits the PC and supports the required connection. A suitable adapter or different cable may be needed, but it cannot make a slower host port faster.
- Check whether the computer supports relevant features such as UASP. Samsung notes in the T7 Shield manual that host support can affect performance.
- Treat manufacturer sequential read and write figures as maximum specifications under stated conditions, not expected backup speeds. Actual backup work also depends on the PC, files, software, and connection.
For example, Samsung lists the Portable SSD T7 Shield as USB 3.2 Gen 2 (10 Gbps), with sequential read up to 1,050 MB/s and write up to 1,000 MB/s. Samsung says performance varies with the host, cable, and system environment, and its manual notes that slower USB versions reduce performance. Those are manufacturer specifications, not independent backup-time measurements. Samsung’s T7 Shield specifications and manual give the model-specific details.
4. Decide whether ruggedness and encryption are worth it
Features matter in context. A drive that stays on a desk may not need the same impact and weather protection as one carried in a bag. Likewise, encryption is useful only if its setup and recovery implications fit your workflow.

Portability and physical protection
Samsung specifies IP65 dust and water resistance and drop resistance up to 3 m for the T7 Shield. These are Samsung’s product claims, not a guarantee that a drive will survive every spill, drop, or accident; consult the product details for test conditions and exclusions. Rugged ratings can be a sensible tie-breaker for a drive that travels, but they do not protect against loss, theft, failure, or accidental deletion.
Encryption and access
Distinguish a drive’s built-in hardware encryption or password-protection feature from Windows volume encryption. They are different mechanisms, and availability and setup depend on the exact product and software. Before enabling a password feature, read the manufacturer’s current instructions and understand how you will regain access if you forget the password. Do not assume a product’s encryption feature is interchangeable with Windows encryption.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.6. Check formatting before using the drive
The T7 Shield manual says the drive is preformatted as exFAT and notes that some host operating systems may require reformatting. Whether that format is appropriate depends on the backup application and any cross-device use you need. Check the backup software’s requirements and the devices that must read the drive before changing its format.
Reformatting can erase data. If the SSD already contains files, copy them elsewhere before reformatting, and do not treat a format change as a harmless compatibility setting. Samsung’s manual describes the T7 Shield’s format and connection guidance.
7. Set up File History and verify the backup
Microsoft’s current support instructions describe connecting an external drive, opening File History settings in Control Panel, choosing the drive if needed, and turning File History on. The exact interface can differ by Windows version or configuration.
- Connect the SSD to the PC.
- Open Control Panel and go to File History settings.
- Select the external drive if Windows has not already selected it, then turn File History on.
- If you need folders beyond the defaults, add them to a library for inclusion, following Microsoft’s instructions.
- After backup has run, restore a sample file or earlier version to confirm that the backup is usable.
Keep another copy stored separately for data that would be difficult to replace. An external SSD can be lost, stolen, damaged, or fail; its warranty does not recover the data on it. Microsoft’s guidance distinguishes backup, restore, and recovery, but it does not define one universal backup rule or certify a single drive as protection against every loss scenario.
Quick Recap
8. Make the final choice
- Choose capacity from the included data, version retention, and expected growth, with room to spare.
- Choose interface to match the PC port and cable; do not pay for a speed tier the PC cannot use.
- Choose protection features according to whether the drive travels and whether you can manage the encryption or password process.
- Verify compatibility with the backup software and intended format before transferring important data.
- Check the exact listing for current capacity options, regional warranty terms, included accessories, and product identity. Prices and price-per-terabyte value were not established by the manufacturer specifications cited here, so compare current local listings rather than assuming one model is the better value.
