The hard drives are a dream. I tested all boards found previously with HD Tune and it was not an error, and the values of the read / write all together top.
At a Glance:
+ Extremely quiet
+ Extremely fast
+ Very cool
At the moment already for 2 months at a time without any problems or errors in the run every 3 SMART test (performed weekly by server).
Strong buy recommendation !!
Ps: Negative rating due to poor packaging are garbage. This had absolutely nothing to do with the plates in itself !!!
