The Kioxia Exceria Plus G3 is a solid-state drive in the M.2 2280 form factor, launched on May 25th, 2023. It is available in capacities ranging from 1 TB to 2 TB. This page reports specifications for the 1 TB variant. With the rest of the system, the Kioxia Exceria Plus G3 interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the PS5021-E21T from Phison, a DRAM cache is not available. Kioxia has installed 112-layer TLC NAND flash on the Exceria Plus G3, the flash chips are made by Kioxia. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are handled more quickly. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The Exceria Plus G3 is rated for sequential read speeds of up to 5,000 MB/s and 3,900 MB/s write; random IO reaches 770K IOPS for read and 950K 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 600 TBW, a typical value for consumer SSDs.

Notes

Controller:

1 main core using Cortex-R5 with CoXProcessor technology running at 980 ~ 1000 MHz (one additional dual-core) Cortex-R5 clocked at a lower clock for better efficiency

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.
Enterprise Endurance: 5.000 up to 7.000 P.E.C.
