The product range is quite large, so the price and the USB 3.0 compatibility was for me PRIMARILY buying decision.
The next day, delivered, unpacked, inserted disks, enclosures, closed up, connect power and USB cables and I already had for just 10 external hard drive.
On the plus side is that it is a separate arrival / off switch. I can not say much, I guess that depends primarily from the SATA hard drive, the incorporating, from about the volume.
So a quick solution for a small price. I am (as measured by the claims, which I had at such a product) completely thrilled!
