Using the file benchmark option in HD Tune Pro, we can see a little more into the drive as the sequential read speed comes in 112 MB/s and the sequential write speed comes in at 105 MB/s.


QuickBench is another benchmark tool used to measure the transfer speeds and performance of storage devices. QuickBench is a good tool for confirming the previously produced read and write speeds seen above.

QuickBench is a great piece of software to run every now and again because it often throws some data at you that you may not have been expecting, which in this case it did.

Unfortunately, we also see at detriment to this drive when looking at the read speed average of 82 MB/s.

  1. I have achieved an ADATA HD 720-1T USB disk. I use it with an ASUS laptop as an external bootable disk for Linux (I have windows 8.1 installed on my SSD laptop drive). On the ADATA drive I have 3 different Linux distros installed. It work just fine (thanks to USB 3.0). Great product..
