In the first purchase I was also really pleased (transfer rate of 90 MB / s, quiet operation and low temperature).
Then I bought the case a second time.
So far so good, but I found that in this case the hard drive no longer goes into hibernation when it is not needed. This has the consequence that the hard drive is ever like 40 degrees.
After some research I found out that the housing have different firmware versions.
Have this regard already obtained from the manufacturer, but so far no response.
This does not bother me though, because I always save on the hard drives only music and movies and therefore the plates switch on only as needed, but this is still annoying.
One thing I have to complain about yet: The USB cable is extremely short! Here 10 cm would have been more beautiful, but everything still fits barely.
********** ********** UPDATE
In the meantime, the manufacturer has provided a firmware update.
With this, the hard drives go back into hibernation.
I now have two (2) bought more housing, so now I have four (4) Housing and am still satisfied.
Until now, each disk was always immediately recognized (2x WD, Hitachi and 1x 1x Samsung).
