SK Hynix Gold P31 NVMe SSD: More Hyjinx from Hynix?


The SK Hynix Gold P31 has SK Hynix LPDDR4-4266. DRAM makes SSD work faster, but also more expensive.

The SK Hynix Gold P31 due to the low density of memory chips can last with no further heat sinks. Some motherboards or laptops from the factory has thermal pads below and above the storage to enhance productivity during times of heavy loads.

The Gold P31 512Gb has maximum write speed 3200 Mbps, sequential read speed 3500 Mbps. NVMe operate on SK Hynix controller and M.2 3.0 x 4 high-speed serial computer expansion bus standard. The NAND memory type is SK Hynix 128L 3D TLC.
