Earlier this year Seagate introduced the Firecuda 510 m.2 NVMe with pci-e 3.0 connectivity. Seagate is following the example of Gigabyte, Corsair, XPG and Patriot and decided it was time to upgrade the Firecuda with a pci-e 4.0 interface and named it Seagate Firecuda 520. The Firecuda 520 is fitted with the Phison PS5016-E16 controller and available in 500GB, 1TB and 2TB capacities.
The Firecuda 520 should be able to reach 5000 MB/s read and 4400 MB/s write speeds in the most ideal circumstances. As most other PCI-E 4.0 NVMe drives are fitted with heatspreaders the Seagate Firecuda 520 is plain with just a branded sticker on top of the controller and memory chips. We do agree with Seagate because most high-end AMD X570 motherboards have a dedicated heatspreader for every M.2. slot. If you purchase a drive from Seagate you will receive a 5 year warranty period.
