The Netac N950e Pro is a solid-state drive in the M.2 2280 form factor, launched in 2020. 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 Netac N950e Pro interfaces using a PCI-Express 3.0 x4 connection. The SSD controller is the SM2262ENG from Silicon Motion, a DRAM cache chip is available. Netac has installed 96-layer TLC NAND flash on the N950e Pro, 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 N950e Pro is rated for sequential read speeds of up to 3,000 MB/s and 1,300 MB/s write.
The SSD's price at launch is unknown. The warranty length is set to five years, which is an excellent warranty period. The TBW rating for the Netac N950e Pro 250 GB is unknown, too.
