The Kioxia Exceria is a solid-state drive in the 2.5" form factor, launched in 2021. It is available in capacities ranging from 240 GB to 960 GB. This page reports specifications for the 960 GB variant. With the rest of the system, the Kioxia Exceria interfaces using a SATA 6 Gbps connection. The SSD controller is the PS3111-S11-13 from Phison, a DRAM cache is not available. Kioxia has installed 64-layer TLC NAND flash on the Exceria, the flash chips are made by Toshiba. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are absorbed more quickly. The cache is sized at 20 GB, once it is full, writes complete at 150 MB/s. The Exceria is rated for sequential read speeds of up to 555 MB/s and 540 MB/s write; random IO reaches 81K IOPS for read and 88K for writes.
The SSD's price at launch is unknown. The warranty length is set to three years, which is above average, but shorter than the five years offered by many other vendors. Kioxia guarantees an endurance rating of 240 TBW, a relatively low value compared to other SSDs.
