Western Digital PC SN8000S SDEPNRK-1T00

SN8000S SDEPNRK-1T00

The Western Digital SDEPNRK-1T00 is a 1 TB SN8000S series NVMe SSD. It appears this M.2 22 by 80 drive never received an official launch; instead, it was quietly unleashed some time in H1 2024.

This PCIe 4 x4 SSD may be slightly more power-hungry than the average PCIe 4 SSD. It can consume up to 10 W if the official spec sheet is to be believed.

Performance

Its performance is not particularly impressive as far as PCIe 4 SSDs go. While AS SSD returns a sequential read rate of way over 6 GB/s, writes are only just about half as fast.
