While both brands offer variations in other sizes, the specific units compared here show a major difference. The iStorage drive holds four times as much data as the Western Digital drive. If you need to store large media libraries or extensive backups, the larger capacity of the iStorage drive is the practical choice over the smaller Western Digital unit.
Security Features
Both drives include hardware encryption, but the iStorage diskAshur2 SSD offers more robust protection details. It uses AES-XTS 256-bit hardware encryption and requires a 7-15 digit PIN for authentication. It also holds a Common Criteria EAL 5+ certification for its secure microprocessor.
