The Mushkin Helix-L has no dynamic random-access memory (DRAM) in their controller or data about it is unknown. Dynamic Random-Access Memory makes drive work faster, but more expensive.

The Helix-L 1Tb due to the low density of memory chips able to run with no further heat sinks. Some laptops or motherboards already has thermal pads above or below the storage to improve productivity during heavy loads.

The Mushkin Helix-L 1Tb has write speed 1500 Mb/s, read speed 1700 Mb per second. It operate on Silicon Motion SM2263XT controller and M.2 3.0 x 4 interface standard. The memory type is TLC.
