The Mushkin Helix-L has no Dynamic Random-Access Memory or information about it is unknown. Dynamic random-access memory (DRAM) in their controller help to improve endurance and IOPS.

The Helix-L 250Gb due to the low density of memory chips can work without extra cooling systems. Some laptops or motherboards from the factory has additional cooling below or above the storage for better productivity during high loads.

The Helix-L 250Gb has write speed 1500 Mbps, maximum read speed 1700 Mb per second. Storage run on Silicon Motion SM2263XT controller and M.2 3.0 x 4 high-speed serial computer expansion bus standard. The NAND memory type is TLC.
