The Nextorage G Series is a solid-state drive in the M.2 2280 form factor, launched on October 4th, 2022. It is available in capacities ranging from 1 TB to 4 TB. This page reports specifications for the 1 TB variant. With the rest of the system, the Nextorage G Series interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the PS5018-E18-41 from Phison, a DRAM cache chip is available. Nextorage has installed 176-layer TLC NAND flash on the G Series, the flash chips are made by Micron. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are absorbed more quickly. The cache is sized at 330 GB. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The G Series is rated for sequential read speeds of up to 7,300 MB/s and 6,000 MB/s write; random IO reaches 750K IOPS for read and 1000K for writes.
At its launch, the SSD was priced at 85 USD. The warranty length is set to five years, which is an excellent warranty period. Nextorage guarantees an endurance rating of 1200 TBW, a good value.
