The ADATA Swordfish has Host Memory Buffer. This means that the storage uses the system's random-access memory for its proprietary needs. Dynamic Random-Access Memory makes drive work faster, but also more expensive.

The Swordfish 250Gb due to the low density of memory chips can last without additional heat sinks. Some laptops or motherboards designed with thermal pads above or below the storage to improve performance during times of high loads.

The Swordfish 250Gb has sequential write speed 1200 Mb per second, sequential read speed 1800 Mb per second. Storage run on Realtek RTS5763DL controller and M.2 3.0 x 4 high-speed serial computer expansion bus standard. The memory type is ADATA 3D TLC.
