About This Product
The Seagate BarraCuda 520 is a 2TB M.2 NVMe PCIe Gen4 x4 SSD. It offers sequential read speeds up to 5000 MB/s and write speeds up to 4400 MB/s, which is typical for early PCIe Gen4 drives. This drive is suitable for general computing and light content creation, providing faster load times than SATA SSDs but not matching the performance of higher-end PCIe Gen4 SSDs.
Verdict
βGood for users seeking a budget-friendly PCIe Gen4 upgrade over SATA SSDs.β
