The Asura Genesis Xtreme is a solid-state drive in the M.2 2280 form factor, launched in 2019. It is available in capacities ranging from 256 GB to 2 TB. This page reports specifications for the 2 TB variant. With the rest of the system, the Asura Genesis Xtreme interfaces using a PCI-Express 3.0 x4 connection. The SSD controller is the PS5012-E12-27 from Phison, a DRAM cache chip is available. Asura has installed 64-layer TLC NAND flash on the Genesis Xtreme, the flash chips are made by Toshiba. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are absorbed more quickly. The Genesis Xtreme is rated for sequential read speeds of up to 3,400 MB/s and 2,750 MB/s write; random IO reaches 490K IOPS for read and 500K for writes.
At its launch, the SSD was priced at 500 USD. The warranty length is set to 7 years, which is a very long warranty, better than most other drives on the market. Asura guarantees an endurance rating of 3115 TBW, a good value.
