The KIOXIA CD8P-R Series KCD81PUG3T84 is a 3.84 TB (3,840 GB) read-intensive data center NVMe SSD in the 2.5-inch, 15 mm form factor. It has a PCIe 5.0 (x4) interface, is NVMe 2.0 compliant, and uses KIOXIA BiCS FLASH generation 5 TLC flash memory with KIOXIA's own controller and firmware. It is rated for 1 DWPD (drive write per day) and carries a 5-year warranty.

The single-port design includes power loss protection and end-to-end data correction, and is built for consistent performance in 24x7 data center environments. KIOXIA rates this 3.84 TB model at up to 12,000 MB/s sustained sequential read (128 KiB) and 5,500 MB/s sequential write, with up to 1,900K IOPS sustained 4 KiB random read and 200K IOPS random write.

This is the base model. KIOXIA also lists Sanitize Instant Erase (SIE) and self-encrypting (SED) variants of this drive under separate part numbers.

Key applications: Hyperscale; IoT and big data analytics; Online transaction processing (transactional and relational databases); Virtualized environments; Streaming media and content delivery networks.
