The Exceria Pro is Kioxia's debut in the highly competitive PCIe Gen4 market. Sitting under Kioxia's Personal Product banner, the Exceria Pro uses the company's own 112-layer TLC NAND together with an eight-channel controller. With the 2TB model priced at just over £370, we put it through its paces and find out if it is worth buying.

The Exceria Pro model line-up comprises just two capacities; 1TB and the flagship 2TB drive we are reviewing here. The 2TB drive uses four packages of Kioxia's own 5th generation 112-layer BiCS5 TLC NAND in combination with a Kioxia branded controller and a 2GB cache IC.

Kioxia quotes Sequential read/write performance for the two drives as up to 7,300MB/s and up to 6,400MB/s respectively. The 1TB drive is rated as up to 1M IOPS for 4K random reads while the 2TB drive is slower at up to 800,000 IOPS. Random write performance is quoted as up to 1.1M IOPS for the 1TB drive with the 2TB drive faster at up to 1.3M IOPS.

Kioxia rate the TBW endurance for the drives at 400TB for the 1TB drive and 800TB for the 2TB model and backs the range with a 5-year warranty.
