The Aorus Gen4 SSD is a solid-state drive in the M.2 2280 form factor, launched on May 30th, 2019. 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 Aorus Gen4 SSD interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the PS5016-E16-32 from Phison, a DRAM cache chip is available. Aorus has installed 96-layer TLC NAND flash on the Gen4 SSD, the flash chips are made by Toshiba. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are processed more quickly. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The Gen4 SSD is rated for sequential read speeds of up to 5,000 MB/s and 2,500 MB/s write; random IOPS reach up to 400K for reads and 500K for writes.
At its launch, the SSD was priced at 140 USD. The warranty length is set to five years, which is an excellent warranty period. Aorus guarantees an endurance rating of 850 TBW, a good value.
