ADATA HV620S 1TB Black
Score: 74/100
Aocesk 2TB Portable SSD
Score: 80/100Rankings
The Aocesk Portable Mobile SSD is an aluminum enclosure for M.2 SATA SSDs, offering up to 2 TB (or user-installed up to 4 TB) of storage with USB 3.1 connectivity and smart hibernation. While its build quality and flexibility are strong points, the lack of NVMe support and modest USB-3.0 speeds limit its appeal for high-performance users.
The ADATA HV620S 1TB is an ultra-slim, glossy-finished portable HDD with USB 3.1 Gen 1 connectivity and a lightweight design. It offers broad OS and console compatibility plus a 3-year warranty, but lacks hardware encryption and is vulnerable to drops. Ideal for users who value portability and capacity over high-speed performance.
