An addendum to my testing of the Transcend JetFlash 710 64 and PNY Elite-X Fit 64 above:
As mentioned, the Transcend threw many errors on the Qu-Pac in multitrack recording. On a Mac, I tested the drive’s speed. Turns out it’s actually a USB 2.0, not 3.1 as labeled on the package (from amazon). It self-reports to the Mac’s System Info that it’s rated speed is actually 480 Mb/s (aka USB 2.0). (For comparison, the PNY Elite-X Fit 64 is rated 5 Gb/s, aka USB 3.0) I also ran speed benchmarks on both drives, and the PNY was 5-8 times faster, as a USB2 vs. USB3 comparison would be. The Transcend is clearly falsely (or even fraudulently) labeled as a USB 3.1 drive, when it’s actually a USB 2.0.
It’s seems that in the world of USB flash drives, you can never be sure what you’re getting. It would be interesting if other users tested their working and non-working drives.
I just tested two new drives, and added them to the list:
PNY Elite-X Fit 64GB – Good. Recorded 4 hours (38GB!) of multitrack with no errors.
Transcend 710S 64GB – Bad. Many errors on multitrack recording, about 2 per minute.
Both went fresh from the package into the Qu-Pac for formatting. I did several recording tests on both, re-formatting before each test. The above results were the same each time. Looks like I’m the first to try the 64GB versions of these. (According to the list, the 32GB versions of both will work.)
I wanted to try these for their form factor; they are physically tiny. I’m glad the PNY Elite-X Fit worked. It’s half the height
of the Qu-Pac’s volume knob! Doesn’t get in the way, won’t get whacked.
