The Aegis Bio is natively formatted in NTFS, so while Windows users will face no issues using drive, Mac users will need to take a couple extra steps, either reformatting the drive or installing extra third-party software like Paragon's NTFS for Mac OS X to write to the drive. [Editor's note: PCWorld also has a review of the Aegis Bios 3.0.]
In terms of speed, the Aegis Bio is a speedy little drive. It comes with built-in USB 3.0, which makes transferring large files to and from the drive a breeze. Macworld Lab used AJA System Test to clock the Aegis Bio's write speed at 103.2 MBps and its read speed at 105.3 MBps. This beat other external drives with USB 3.0 connections that we've tested, such as the 1TB G-Technology G Drive Mobile and the 1TB Seagate Backup Plus. Motor sounds from the drive were hardly noticeable throughout the tests, and the unit remained relatively cool.
The Aegis Bio is available in three different size capacities: 500GB ($199), 700GB ($219), and 1TB ($249). It's more expensive than other portable drives--the 1TB Seagate Backup Plus can be for just over $100--but the Aegis Bio is aimed at users with security concerns.
The Aegis Bio really shines in the extra security and protection it provides for you and your data. The Aegis Bio is meant for users who want to make sure that their files remain secure, and are willing to pay for it.
