Manufacturer description

The Seagate FireCuda 520 1TB steps up from PCIe Gen3 with sequential reads up to 5,000MB/s and writes up to 4,400MB/s, roughly 45% faster than a Gen3 NVMe drive by Seagate's own measure. Built on 3D TLC NAND in the standard M.2 2280 form factor, this Gen4 x4 NVMe 1.3 drive drops into PCIe Gen4 motherboards and AMD Ryzen platforms without extra configuration, and stays backwards compatible with PCIe 3.0 systems if you upgrade the board later. Endurance is where this FireCuda separates itself from budget NVMe drives: 1.8 million hours MTBF and up to 2,800TB written across the family, which…
