The Apacer AS2280Q4 is a solid-state drive in the M.2 2280 form factor, launched on July 17th, 2019. It is available in capacities ranging from 500 GB to 2 TB. This page reports specifications for the 2 TB variant. With the rest of the system, the Apacer AS2280Q4 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. Apacer has installed 96-layer TLC NAND flash on the AS2280Q4, 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 AS2280Q4 is rated for sequential read speeds of up to 5,000 MB/s and 4,400 MB/s write; random IOPS reach up to 750K for reads and 750K for writes.
The SSD's price at launch is unknown. The warranty length is set to five years, which is an excellent warranty period. Apacer guarantees an endurance rating of 3350 TBW, a good value.
