Speeds will slower for USB 2.0 ports which are limited to about 30 MB/s maximum.
The performance with a Fake USB tester showed write speeds of 8.341 MB/s for a full test which is very respectable as the tester is very demanding for checking each block to be sure its valid. Reading back the test data was very close to 88.1 MB/s which shows the JetFlash 790K can deliver the speeds indicated.
Installing Windows 10 from the Transcend JetFlash 790K was much faster than with older slower USB sticks. The copy process was almost instantaneous however unpacking the files is CPU bound and can take a few minutes even with a SSD system drive.
Transcend JetFlash 790K is plenty fast enough to play high bit rate HD and UHD content directly. The performance of the new generation of USB storage is excellent.
We like the retractable design on the JetFlash 790K as it eliminates the problem of a lost cap.
