The Kioxia Exceria G2 is a solid-state drive in the M.2 2280 form factor, launched in July 2021. It is available in capacities ranging from 500 GB to 2 TB. This page reports specifications for the 500 GB variant. With the rest of the system, the Kioxia Exceria G2 interfaces using a PCI-Express 3.0 x4 connection. The SSD controller is the PS5012-E12S-32 from Phison. Kioxia has installed 112-layer TLC NAND flash on the Exceria G2, the flash chips are made by Toshiba. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are handled more quickly. The Exceria G2 is rated for sequential read speeds of up to 2,100 MB/s and 1,700 MB/s write; random IO reaches 360K IOPS for read and 400K for writes.
The SSD's price at launch is unknown. The warranty length is set to five years, which is an excellent warranty period. Kioxia guarantees an endurance rating of 200 TBW, a relatively low value compared to other SSDs.

Notes

Controller:

2 main cores using Cortex-R5 clocked at 667 MHz with CoXProcessor technology (one additional dual-core) Cortex-R5 clocked at a lower clock for better efficience. The difference between this revision and the E12 revision is that this has a nichel IHS to improve the temperature, a smaller size, smaller node (12nm TSMC FinFET) and this works with less DRAM capacity.

NAND Die:

Although this Die is a 4-plane design, most Kioxia BiCS5 NAND Dies used in most SSDs are dual planes design because of Yield and production cost.
And because of the die being dual-plane the Throughput is cut in half to 66 MB/s per die.
There is no CuA (Circuitry under Array) in the Dual-Plane variant.
Typical Endurance: 1700 P.E.C.
Rated Endurance: 3.000 to 5.000 (up to) P.E.C.
