The Kingston NV2 is a solid-state drive in the M.2 2280 form factor, launched on September 7th, 2022. It is available in capacities ranging from 250 GB to 4 TB. This page reports specifications for the 1 TB variant. With the rest of the system, the Kingston NV2 interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the PS5021-E21T from Phison, a DRAM cache is not available. Kingston has installed 112-layer TLC NAND flash on the NV2, the flash chips are made by Toshiba. Please note that this SSD is sold in multiple variants with different NAND flash or controller, which could affect performance, the "Notes" section at the end of this page has more info. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are processed more quickly. The cache is sized at 88 GB, once it is full, writes complete at 600 MB/s. Copying data out of the SLC cache (folding) completes at 100 MB/s. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The NV2 is rated for sequential read speeds of up to 3,500 MB/s and 2,100 MB/s write.
At its launch, the SSD was priced at 80 USD. The warranty length is set to three years, which is above average, but shorter than the five years offered by many other vendors. Kingston guarantees an endurance rating of 320 TBW, a relatively low value compared to other SSDs.

Notes

Drive:

Kingston might swap components in the future in order to meet the volume demands for this product
Dies could be BiCS4

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.
Rated Endurance: 5.000 (up to) P.E.C.
