The Wicgtyp NV940 is a solid-state drive in the M.2 2280 form factor, launched in 2022. It is available in capacities ranging from 512 GB to 2 TB. This page reports specifications for the 2 TB variant. With the rest of the system, the Wicgtyp NV940 interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the SM2269XT from Silicon Motion, a DRAM cache is not available. Wicgtyp has installed 176-layer TLC NAND flash on the NV940, the flash chips are made by Micron. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are soaked up more quickly. The cache is sized at 170 GB. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The NV940 is rated for sequential read speeds of up to 5,120 MB/s and 4,600 MB/s write.
At its launch, the SSD was priced at 138 USD. The warranty length is set to three years, which is above average, but shorter than the five years offered by many other vendors. The TBW rating for the Wicgtyp NV940 2 TB is unknown.

Notes

Controller:

The difference between this and the non-XT revision is that this revision doesn't support DRAM, in fact it supports HMB (Host Memory Buffer). Also, this revision has a different package (247-balls FCCSP).

NAND Die:

This Flash can run safely at 1600 MT/s (800 MHz)
tPROG with overhead: ~ 533 µs (Avg 120 MB/s per die)
