SanDisk Extreme Pro USB 3.0 128GB

Excellent Flash Drive

As my latest review item I have to give this flash drive two thumbs up!

SanDisk SecureAccess software works well, no issues on Windows 7

Test as follows:

Very nice flash drive which has speed worthy of the USB 3.0 designation. Was able to transfer over 12.5GB of music to the drive in just a little over 1 minute... a 1.5 GB movie in only about 12 seconds.

SanDisk SecureAccess software has no use on my Linux systems so I can recover about 10MB of space by dumping the extra proprietary software (of course I use trucrypt on them anyway).

Actual test numbers are only marginally better on my Ubuntu 12.04 system. Results using disk utility as follows:

Minimum Read Rate: 109.6 MB/s Minimum Write Rate: 119.0 MB/s

Maximum Read Rate: 126.3 MB/s Maximum Write Rate: 144.0 MB/s

Average Read Rate: 122.8 MB/s Average Write Rate: 134.8 MB/s

Average Access Time: 0.5 ms

Very pleased with the over-all performance and design of the drive, much better than the old Cruisers. Sleek design, retractable, lightweight aluminum housing that has a slot for key ring mounting will hold up much better than the plastic counterparts, the aluminum might aide in cooling as well? (although during testing my unit never even showed any noticeable increase in temperature).

Price for this units might scare away some people but as I see it, the performance of this drive can justify a $1 per GB price.
