Samsung T7 Shield
Score: 75/100Rankings
The WD_BLACK SN770 2TB is a DRAM-less PCIe Gen4 SSD delivering up to 5150 MB/s reads and 4850 MB/s writes with a robust 1200 TBW endurance. Its budget-friendly price and low power draw come at the cost of no onboard DRAM and no included heatsink, which can limit sustained performance under heavy loads. Ideal for gamers and mainstream builders seeking fast sequential performance without the premium price.
The Samsung T7 Shield is a rugged portable SSD delivering up to 1,050 MB/s read speeds and strong IP65 protection. Its added rubberized shell makes it heavier and slightly bulkier than the standard T7. Ideal for photographers and gamers who need durability in harsh environments.

Professional reviewers regard the WD_BLACK SN770 as a compelling budget-friendly PCIe Gen4 SSD that punches above its weight class, delivering flagship-like sequential speeds and solid endurance while keeping costs low. They commend its value, fast load times, and low power draw, but warn that the DRAM-less design and lack of a heatsink could limit sustained performance in demanding scenarios.
General users praise the drive for its rapid game loading, smooth everyday performance, and easy installation, seeing it as a solid value for a 2 TB capacity. Recurring concerns revolve around thermal throttling without a heatsink and occasional slowdowns during long write operations, especially for those expecting flagship-level consistency.
Professional reviewers such as Shuttermuse and Guru3D commend the T7 Shield for its combination of flagship-class NVMe speeds and rugged IP65 protection, calling it a tough, high-performance solution for photographers and mobile professionals.
