Kioxia CD8-R 1.92TB PCIe 4.0 x4 NVMe U.3 2.5-inch Data Center Solid State Drive

This is a 2.5" U.3 SFF part on PCI Express NVMe 4.0 x4. It fits any bay wired for PCI Express NVMe 4.0 x4. Send us your server model and we will confirm backplane support, firmware level and any bracket or caddy required before you order. That check is part of every order we ship.

1 DWPD (read-intensive). Across 1.92TB of capacity that is approximately 3.5 PB of total writes over a five-year term, calculated from the drive-writes-per-day rating. Compare that against your workload's measured daily write volume: if you are writing more than 1.9TB a day to a single drive, ask us about the mixed-use alternatives instead.

They are the same drive line in a different capacity, with the same PCI Express NVMe 4.0 x4, 2.5" U.3 SFF and endurance rating. The 3.84TB gives you 2.0x the capacity per bay. Where bays are the constraint (a full backplane, or a rack you cannot grow), the larger capacity is usually cheaper per usable terabyte once you count the chassis it saves. Ask us for both on one quote and compare.

Up to 6,800 MB/s sequential read and up to 4,200 MB/s sequential write, which is what PCI Express NVMe 4.0 x4 allows. Sustained figures under a real mixed workload land lower than the sequential headline. Tell us your access pattern and queue depth and we will tell you what to expect rather than quoting the datasheet at you.

Yes. We supply through authorized distribution only, so the part carries the full Kioxia manufacturer warranty and its firmware update path stays supported. No grey-market stock, no re-labelled drives, no voided warranties.
