Score: 80/100Rankings
The Samsung T7 1TB Portable SSD offers blazing USB 3.2 Gen 2 speeds and strong hardware encryption in a lightweight aluminum case. Performance drops on older ports and it lacks biometric security. Ideal for mobile professionals needing fast, secure on-the-go storage.
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.

Professional reviewers consistently commend the T7 for its sleek metal chassis, exceptional read/write speeds, robust AES-256 encryption, and effective thermal management that prevents throttling. They also note that the drive's performance hinges on using a USB 3.2 Gen 2 connection and point out minor issues such as inconsistent weight reporting and the lack of fingerprint security found on the T7 Touch variant.
Everyday users praise the SSD's rapid 4K video and game file transfers, its pocket-friendly size, and reliable cross-platform operation. Recurring themes include occasional heat under sustained loads, concerns about cable durability, and speed reductions when paired with older USB ports, while most buyers are satisfied with the overall value and build quality.
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.
