The Addlink A95 is a solid-state drive in the M.2 2280 form factor, launched on September 16th, 2021. It is available in capacities ranging from 1 TB to 4 TB. This page reports specifications for the 4 TB variant. With the rest of the system, the Addlink A95 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. Addlink has installed 176-layer TLC NAND flash on the A95, the flash chips are made by Micron. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are soaked up more quickly. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The A95 is rated for sequential read speeds of up to 7,400 MB/s and 7,000 MB/s write; random IOPS reach up to 1000K for reads and 1000K for writes.
At its launch, the SSD was priced at 799 USD. The warranty length is set to five years, which is an excellent warranty period. Addlink guarantees an endurance rating of 3000 TBW, a typical value for consumer SSDs.
