The SK hynix PC801 HFS512GEJ9X101N BF is a 512 GB M.2 2280 NVMe SSD. Available benchmark databases show a 30.1-point DiskSpd rating and AS SSD Copy Game results from 1,051.44 to 2,124 MB/s, but those figures come from different methods and, for the copy test, different computers. They are useful observations—not a single guaranteed speed for your laptop.
SK hynix PC801 HFS512GEJ9X101N BF specifications
Notebookcheck identifies the exact drive as an SK hynix PC801 with model number HFS512GEJ9X101N BF, 512 GB capacity, M.2 2280 form factor and NVMe interface. It lists an announced date of 16 December 2022. Notebookcheck’s exact-model profile is the source for these identification details.
What benchmark results are listed?
| Benchmark and source | Reported result | How to interpret it |
|---|---|---|
| DiskSpd performance rating — Notebookcheck | 30.1 points | A database rating, not a sequential speed in MB/s. |
| AS SSD Copy Game — Notebookcheck | 1,051.44–2,124 MB/s across four listed computer configurations | Results vary across host systems and are not four controlled runs on one computer. |
| Nero Score user-submitted profile — model identifier HFS512GEJ9X101N | Top total score: 4,385; sequential read/write: 6,832/4,952 MB/s; 4K random read/write: 3,356/1,971 MB/s | Database observations based on user submissions, not a controlled review of the exact BF variant. |
How to read the Notebookcheck results
Notebookcheck lists the AS SSD Copy Game values across a Lenovo Yoga 9 14IRP G8, HP EliteBook 840 G9, HP EliteBook Ultra G1q 14 and HP Victus 16-r0076TX. Because the computers differ, the 1,051.44–2,124 MB/s range reflects host and workload context as well as the drive. It should not be read as a repeatable minimum-to-maximum range measured on one system.
The 30.1-point DiskSpd rating is a separate metric; it cannot be converted directly to MB/s. Likewise, Nero Score’s sequential and random figures use a different benchmark and a user-submitted profile. The values from these sources are not interchangeable, and neither source establishes that every HFS512GEJ9X101N BF will reproduce those results in a particular laptop.
#1 Best Overall
- Sequential read/write (MB/s) up to: 3400/2500
- Random read/write (IOPS) up to: 390K?420K
- Compatible with all systems that support M.2 2280 NVMe PCIe 3.0 x4
Can these results predict performance in your laptop?
Only roughly. An SSD benchmark result depends on the test, host computer and workload, so a score gathered on another system is not a promise of the same performance in yours. A fair comparison between drives requires the same benchmark version, host, drive state and workload. The available sources do not provide a controlled side-by-side comparison for this model.
Notebookcheck’s AS SSD Copy Game observations are especially tied to the four named computer configurations. Nero Score adds another data point for the PC801 model identifier, but because its profile is user-submitted and does not establish a controlled test of the BF variant, it should be treated as supplementary rather than definitive.

What the published results do not establish
The available benchmark profiles do not establish official rated sequential speeds, endurance or TBW, NAND configuration, controller, warranty, power draw or thermal behavior for this exact variant. Avoid inferring those details from related PC801 models or from submitted benchmark scores.

Check the exact model before buying
If you are identifying or shopping for this drive, match the complete part number, HFS512GEJ9X101N BF, and confirm compatibility with the intended laptop or computer. The model’s M.2 2280 form factor and NVMe interface do not by themselves prove that a particular system supports it. The benchmark listings do not establish compatibility across devices or current marketplace availability.
