Review on iStorage diskAshur2 HDD 1TB Black - Password Protected Portable Hard Drive - Secure, Dust and Water Resistant, Military Grade Hardware Encryption - USB 3.1 IS-DA2-256-1000-B by Dave Hersma

This is a great solution when you need highly secure storage that can be moved between different device types. Other SSDs require an unlock program to run on the device. This causes problems when switching between computers or a mobile device. There are no such problems with this product. It is completely standalone and works with everything. Keep in mind that the keyboard and very solid body make it bulkier than average, but it's still very portable.
