IoSafe Solo G3
Bottom Line

The ioSafe Solo G3 external hard drive combines extreme durability, good USB 3.0 speeds and robust data-recovery options. It's certainly pricey, but its military-grade enclosure can withstand both fires and floods, making the Solo G3 a go-to choice for those who need or want the very best stronghold for their data that money can buy. Owners also find it quiet and easy to use.


Quicker and quieter than it looks. While its massive exterior doesn't exactly suggest speed, the ioSafe Solo G3 boasts fast USB 3.0 transfer rates. CNET's Dong Ngo tests its USB 3.0 speed against 15 other external hard drives, finding that the Solo G3 tops the chart for read and write performance. USB 2.0 speeds are less stellar, with the drive testing out a little below average. The Solo G3 is preformatted for Windows (NTFS) but can be configured for Mac (HFS+). There's no internal fan, so the drive runs quietly. Users at and find it easy to set up and use, as well.

ProsExtremely durable, Fast USB 3.0 speeds, Easy to use, Includes one year of data-recovery serviceConsVery large and heavy, High cost per GB


Survives nature's wrath. The ioSafe Solo G3 is built like a tank. IoSafe says it can protect data from submersion in water up to 10 feet deep for three days and withstand temperatures up to 1,550 degrees Fahrenheit. In the event of a mini-cataclysm, the Solo G3 includes one-time access to the company's data-recovery service, including up to $2,500 of forensic data recovery (which the company bills at $150/hour). The warranty and data coverage is for one year, but it can be extended to three or five years for a fee. The only disaster your data won't survive, Ngo warns, is a drive failure; the Solo G3 is a single-volume drive that can't save backups of your backups.


Immortality comes at a price. The ioSafe Solo G3 external hard drive costs considerably more per GB than traditional backup drives. For many, that may make the Solo G3 overkill. But if you need literally bullet-proof data protection, no external backup hard drive does it better. Whether that kind of peace of mind is worth this drive's premium price tag is a question you'll have to answer for yourself.
