Could This Be The FASTEST NVMe SSD Yet? Seagate Firecuda 520


The Seagate FireCuda 520 has Nanya DDR4. Dynamic random-access memory (DRAM) in their controller help to increase endurance and IOPS.

The Seagate FireCuda 520 2Tb due to the high density of memory chips requires installation of extra heat sink. This decrease temperature of the controller and memory. Some motherboards already has thermal pads below or above the storage for improving performance during high loads.

The FireCuda 520 2Tb has sequential write speed 4400 Mb/s, sequential read speed 5000 Mbps. It works on Phison PS5016-E16 controller and M.2 4.0 x 4 interface standard. The NAND flash memory type is Toshiba 3D TLC.
