Score: 85/100Rankings

The iStorage datAshur PRO 8 GB USB 3.2 flash drive delivers military-grade encryption, rugged IP57 protection and high transfer speeds. Its drawbacks are the tiny 8 GB capacity, need for periodic battery charging and a bulkier form factor. Best suited for government, military or healthcare professionals needing secure, durable portable storage.

The SanDisk Extreme PRO 1 TB USB-A flash drive delivers blazing 420 MB/s read and 380 MB/s write speeds within a rugged aluminum case and a lifetime warranty. Its USB-A connector and lack of water/dust protection may limit use with newer USB-C-only devices and harsh environments. Best for photographers and videographers needing fast, high-capacity portable storage with strong durability.
