The Kingston NV1 is a solid-state drive in the M.2 2280 form factor, launched on May 6th, 2021. It is available in capacities ranging from 250 GB to 2 TB. This page reports specifications for the 250 GB variant. With the rest of the system, the Kingston NV1 interfaces using a PCI-Express 3.0 x4 connection. The SSD controller is the SM2263XT from Silicon Motion, a DRAM cache is not available. Kingston has installed 96-layer QLC NAND flash on the NV1, the flash chips are made by Micron. 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 NV1 is rated for sequential read speeds of up to 2,100 MB/s and 1,100 MB/s write.
At its launch, the SSD was priced at 35 USD. The warranty length is set to five years, which is an excellent warranty period. Kingston guarantees an endurance rating of 60 TBW, a relatively low value compared to other SSDs.

Notes

Controller:

The difference between this and the non-XT revision (SM2263, SM2263G, SM2263ENG, etc.) is that this revision doesn't support the DRAM cache, in fact it uses HMB (Host Memory Buffer).
