The HP FX 900 has HMB. It means that the storage uses the host system's random-access memory for its personal activities. Dynamic Random-Access Memory makes storage work faster, but more expensive.

The HP FX 900 due to the low density of memory chips may function with no further heat sinks. Some motherboards or laptops already has thermal pads above or below the drive for better performance during high loads.

The HP FX 900 has sequential write speed 4800 Mbps, maximum read speed 5000 Mb/s. NVMe operate on Innogrit IG5220BAA controller and M.2 4.0 x 4 high-speed serial computer expansion bus standard. The NAND memory type is MicronTLC.
