All seem to have heat problems if you don't tweak the design a little. Some bad reviews complain that not every byte is available.
All of them seem OK and work so nothing stands out.
It's not JBOD but what about the Drobo?
They all seem to be priced $100-200, and they all seem to be of low quality, with many bad reviews. Are there any good ones? I would like one with usb 3.0 and esata, if possible. Is Mediasonic any better or worse than the others?
