We kind of gave up tracking that kind of data because it could be just about anything from a Green to a Red possibly or even an Se. Just depends on what's available to them at the time. We can check and see what these are though just to solve your curiosity.

What transfer sizes were used for benchmarking purposes?

Would be curious to know if there are significant differences between external drives, especially at smaller block sizes...

Also did the drives have any performance issues on any of the test systems? We've occasionally started to test for that for some customers here-- some drives, despite connecting at USB 3.0 speeds, don't always seem to transfer at full speed (despite the host OS reporting a good USB 3.0 link). Granted, haven't seen it often enough to be a problem... but am curious if any such testing like that goes on, even in an informal nature.

Our sequential test uses a 2MB transfer size (and a 500MB test file size) to show realistic speeds of files getting moved around. We haven't done a lot of the smaller transfer size testing since manufacturers started to multi-source HDDs. We've seen some models span 5,400-7,200RPM models, which might have a small difference in large sequential transfers but have huge differences in small-block stuff. Since many won't pin it down, its a test that can cause confusion if a buyer gets a product with the slower of the drives installed.

We haven't seen issues relating to USB 3.0 speeds for a while, and generally most have been system specific. On one platform a driver causes some pain every once in a while, where one port negotiates at USB 2.0 and the other does USB 3.0 (both in the USB 3.0 group) for all devices.

Exactly. That's the beauty of having an external drive business. Some use 'not good enough' Enterprise/Nearline/Desktop drives. There would a lot of inventory not be usable otherwise.

Well WD is blazing a trail then with a ton of branded gear that's actually really nice. Their interface design and ease of use is impressive in the new NAS line. And there's a pretty fun announcement coming on the 10th you might enjoy.
