The Kioxia Exceria has 1GB DDR4 SLC-Cache. Dynamic random-access memory (DRAM) in their controller help to increase endurance and IOPS.

The Exceria 1Tb due to the low density of memory chips able to function with no additional heat sinks. Some laptops or motherboards from the factory has additional cooling below or above the storage for improving performance during times of heavy loads.

The Kioxia Exceria 1Tb has maximum write speed 1600 Mb per second, sequential read speed 1700 Mbps. Storage run on Toshiba TC58NC1202GST controller and M.2 3.0 x 4 interface standard. The NAND memory type is Toshiba 3D TLC.
