External drives cover the gap between a NAS and a USB stick — a single-cable backup target for a desktop, or a pocket SSD for moving large files between sites without depending on upload speed. Desktop externals (WD My Book, Toshiba's larger Canvio/Basics units) trade portability for capacity; portable SSDs (Kingston XS series) trade capacity for size and drop resistance.
We stock Toshiba Canvio and Basics portable HDDs, WD My Book desktop externals and My Passport portable HDDs, Kingston's XS1000/XS2000 portable SSD line, and Synology's BeeDrive personal backup drive. All ship USB-powered — no external adapter — except the larger-capacity desktop units.
