The IoSafe SoloPro is an external hard drive designed with a very specific user in mind. It's huge, heavy, and comparatively expensive, starting around $250 for 1TB ($320 for 1.5TB and $420 for 2TB). To compensate for these shortcomings, it comes with layers of protection designed to guarantee the survival of data it contains, even against extreme heat and water submersion. Oddly, the drive doesn't support RAID or any other redundancy to safeguard data from commonplace hard-drive failure.
If you live in an area with high risk of fire or flood and want to keep the backup of your important data intact, look no further than the IoSafe SoloPro. Otherwise, we'd recommend any other traditional USB 3.0 external hard drives such as the WD My Book 3.0 or the Seagate GoFlex Desk.
Design and features
The SoloPro looks like a gigantic brick with rounded corners. It's as heavy as you'd expect, given the design; it's about 10 times the weight of the Seagate GoFlex Desk. That said, it doesn't look half bad.

On the front, the SoloPro has a large LED light that indicates the power status (solid blue) and hard-drive activity (flashing blue). On the back, it has one USB 3.0 port, a small ventilation fan, and an on/off switch. The drive comes with either a USB 3.0 port or an eSATA port (we reviewed a USB 3.0 unit). There's no option that includes both of these high-speed ports. Like other USB 3.0-based external hard drives, the SoloPro is backward-compatible with USB 2.0.
The drive ships with nothing but a power cable and a USB 3.0 cable. Our test unit was painted with regular black paint, but a version using heat-resistant paint is available for an extra $20.
The reason the drive is so big and heavy is because of the multiple layers of protective material that keeps the internal hard drive safe from extreme heat (up to 1,550 degrees Fahrenheit for 30 minutes). The drive is also able to survive water submersion up to 10 feet for three days.
Though we didn't have the resources to test the drive against these extreme conditions, IoSafe has shown us demonstrations. The most recent demo was at CES 2010, where it ran a similar drive, the Solo SSD, through a series of extreme tests. After the barrage of tests, the data that was stored on the drive was easily retrieved.
Despite the large size, the SoloPro is a single-volume external hard drive. This means it doesn't support any RAID configurations (such as RAID 1, which safeguards the data against a single-drive failure). So although the data could survive extreme conditions, it might be lost if the internal hard drive dies from defects, mechanical problems, or just general wear and tear over time. Users are not able to replace the internal hard drive on their own. Once the chassis is opened, IoSafe no longer guarantees the effectiveness of the SoloPro's protection.
