SanDisk Ultra Backup USB drive
The SanDisk Ultra Backup USB Flash Drive is a one-touch backup solution and USB memory stick. We tested the 32GB version.
- Easy to use, one-touch backup
- Feels flimsy, expensive
Overall, the SanDisk Ultra Backup is a very cool little drive with respectable speed and plenty of conveniences, although you're paying a premium for those creature comforts. But if you like the idea of backing up data on a device the size of a pack of chewing gum with the press of a finger, we can recommend the SanDisk.

SanDisk Ultra Backup: Speed
The drive backs up remarkably fast. We first backed up 1,991 files - a mixture of text documents, photos and videos — in about 45 seconds. Obviously, backups are pointless without the ability to retrieve data, and this drive's restore feature works flawlessly and quickly. Restoring all of those files to a desktop folder took about five seconds.
There is also an "archive" feature that allows you to store your previous backup in a separate folder on the drive and start a backup in a folder. And with the drive's "clean up" feature, you can also permanently delete a previously archived backup and start a new backup in a new folder.
The SanDisk Ultra Backup is billed as a "high speed" device, which means nothing than that it uses USB 2.0 and should deliver data transfer rates of up to 480Mbits/sec. Since the packaging says high speed, that means benchmark testing.
We used ATTO Technology's ATTO Disk Benchmark v2.3.4, and Simpli Software's HD Tach v3.0.4 benchmarking utilities to perform my read/write performance tests. ATTO showed that the drive had an 18.4MB/sec write rate and a burst speed of 27.4MB/sec HD Tach showed an average write rate of 19MB/sec, an average read rate of 23.6MB/sec, and a burst speed of 27.6MB/sec CPU utilisation was 11 percent and random access time was 0.6 milliseconds.
By comparison, the IronKey Secure USB flash drive — the fastest we've yet tested — offers 31MB/sec burst speed, 29.6MB/sec average write speed and 22 percent CPU utilisation. Another good-performing drive is the Corsair Survivor, which offers 25.1MB/sec burst speeds, 23.6MB/sec average read speed and 4 percent CPU utilisation.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.
For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.
The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.
My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
