OWC Envoy Pro = OWC Envoy Pro USB 3.0 with Aura Pro 480G Flash Blade
VisionTek Pocket (O) = VisionTek USB 3.0 Pocket 256G Flash Drive (OS X Extended format)
VisionTek Pocket (M) = VisionTek USB 3.0 Pocket 256G Flash Drive (MS-DOS FAT format)
SanDisk Extreme Pro = SanDisk Extreme Pro 128G Flash USB 3.0 'Thumb' Drive
PNY Turbo = PNY Turbo 128G Flash USB 3.0 'Thumb' Drive
Test 'mule' was a 'late 2013' Retina MacBook Pro with two SuperSpeed USB 3.0 ports.
RED graph bar means the fastest overall in Megabytes per Second.
LARGE SEQUENTIAL TRANSFER TEST
We used the QuickBench custom sequential 1GB test (average of 5 cycles).
The VisionTek USB 3.0 Pocket SSD bridges the gap between small fast USB 3.0 flash thumb drives and the faster SuperSpeed USB 3.0 bus-powered flash drives.
It even has enough capacity and speed to serve as an alternate boot volume (including Windows, Mac OS X and Linux). Notice we included the results for the Pocket SSD formatted two ways: Mac OS Extended (Journaled) and MS-DOS (FAT). The second format is the default for most thumb drives including the SandDisk and PNY thumb drives we included in the graphs.
BTW, the VisionTek Pocket SSD has a full LSI 2281 SandForce processor complete with all the DuraClass technologies which DuraWrite for wear-leveling and 7% Over Provisioning. That's very important to know since the slower, lower cost USB Jump drives don't have those features and eventually the flash cells will wear out since the writes are not managed over the entire drive and there are no spares.
As you can see from the photo below, at 2.0 x 1.2 x 0.2 inches, at Pocket SSD is the size of a large thumb drive. At 37 grams, it is lighter than the Envoy Pro (140 grams including the USB3 cable) but heavier than the SanDisk Extreme Pro (17 grams) and PNY Turbo (10 grams).
