Netac over the weekend released the NV5000-t, an M.2 NVMe SSD that takes advantage of the PCI-Express 4.0 x4 host interface, offering mid-range performance. Available in 500 GB and 1 TB capacities, the drive uses an unspecified type of 3D NAND flash memory, and a DRAMless controller design. On offer, are sequential transfer rates of up to 4800 MB/s reads, with up to 4600 MB/s writes for the 1 TB variant. The 500 GB variant writes sequentially at speeds of up to 2700 MB/s, but with the same up to 4800 MB/s reads. The 1 TB variant offers endurance of 640 TBW, while the 500 GB variant does 320 TBW. Both models are backed by 5-year warranties. The company didn't reveal pricing.
 
A mid-range M.2 which has good specs and warranty if priced reasonably.
