Durability and Protection
The SSK 1TB Direct-Plug USB-C Portable SSD offers superior physical protection. It features an aluminum alloy shell with IP65 dust and water resistance. It also provides 2-meter drop protection and supports SMART and TRIM commands for stable long-term operation. The SSK 1TB Dual USB-C USB-A External SSD uses a zinc alloy shell with shock resistance and fast heat dissipation. It includes double-head protective covers for its ports. While both are robust, the direct-plug model has explicit ratings for water and dust resistance that the dual-port model does not list.
Compatibility
Both drives offer wide compatibility across modern and older devices. The SSK 1TB Dual USB-C USB-A External SSD works with Windows, Mac OS, Linux, and Android devices.
