The iStorage datAshur 8GB's combination of hardware encryption, physical keypad and tamper-proofing make it virtually un-hackable. We put this USB flash drive through its paces. Here's our iStorage datAshur 8GB video review.

The iStorage datAshur is available in 4GB, 8GB and 16GB capacities. It differs from most flash drives in length, being a little longer to accommodate the keypad. The drive includes a full-length anodised aluminium sleeve to help protect against dust and water. Overall build quality is smart but tough.

To unlock the iStorage datAshur drive the user must enter a 7 to 14-digit code before inserting it into a USB port. Buttons are quite small so large fingers may have some difficulty finding the right key.

The keypad on the iStorage datAshur is critical for security as it means the drive works independently from a computer and prevents a keylogger from recording a code entered via a PC keyboard. It also means the drive works with any modern operating system and doesn’t require any specific software or drivers.
