The Galax HOF Pro 20 is a solid-state drive in the M.2 2280 form factor. It is available in capacities ranging from 512 GB to 2 TB. This page reports specifications for the 2 TB variant. With the rest of the system, the Galax HOF Pro 20 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. Galax has installed 96-layer TLC NAND flash on the HOF Pro 20, 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 HOF Pro 20 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 700K for writes.
At its launch, the SSD was priced at 315 USD. The warranty length is set to five years, which is an excellent warranty period. Galax guarantees an endurance rating of 3500 TBW, a good value.
