Western Digital SN850X short review

Works great with my PlayStation5. Transferring game files from internal SSD to M.2 SSD is fast. Physically looks good with the included heatsink if you'll be using this on a PC with a glass side panel. Good endurance rating though not as high as the Seagate Firecuda 530. Price is still a bit steep compared to other brands with the same storage capacity. Still an overall great M.2 NVMe SSD.
