I bought the hard disk for my Windows Home Server 2011. She's with me now for some 370 hours of continuous use 24/7. The hard drive is virtually inaudible and with 43 ° C very cool (Server: μ-ATX, Intel Atom and are passively cooled to the power supply). The speed I can not really evaluate because here is my 1Gbit connection to the PC the bottleneck.
