Mushkin Helix-L M.2 NVMe SSD Review


The Helix-L 120Gb has no Dynamic Random-Access Memory in their controller or data about it is unknown. DRAM makes SSD work faster, but more expensive.

The Mushkin Helix-L due to the low density of memory chips can operate without additional heat sinks. Some motherboards or laptops from the factory has thermal pads below and above the drive to improve performance during times of heavy loads.

The Helix-L 120Gb has sequential write speed 1500 Mb per second, maximum read speed 1700 Mbps. NVMe works on Silicon Motion SM2263XT controller and M.2 3.0 x 4 interface standard. The NAND flash memory type is TLC.
