Rating: 8.0.

We've already looked at two drives in the Kioxia SSD range, the flagship Exceria Plus NVMe M.2 and the SATA 2.5in Exceria. Today we take a look at the third drive in the range, the mainstream Exceria NVMe. Priced around the £100 mark for the 1TB model, could this be your next SSD?


Formally known as the Toshiba RC500, the Exceria NVMe uses a combination of a quad-channel controller and Kioxia 96-Layer BiCS 4 96-layer 3D TLC NAND.  The drive is available in three capacities; 250GB. 500GB and the flagship 1TB drive of the range we are reviewing here.

Random 4K performance figures (QD32 T8) for the 1TB model are up to 350,000 IOPS for reads and up to 400,000 IOPS for writes. The entry-level 250GB is rated as up to 200,000 IOPS and 290,000 IOPS for read and writes respectively. The 500GB drive is rated as up to 350,000 IOPS for reads and up to 400,000 IOPS for writes.
