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 512 GB 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 processed more quickly. The cache is sized at 85 GB, once it is full, writes complete at 800 MB/s. Copying data out of the SLC cache (folding) completes at 420 MB/s. 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 5,190 MB/s and 2,610 MB/s write.
At its launch, the SSD was priced at 46 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 512 GB is unknown.
