I have 15 of these drive in one of my fileservers. Using Lian Li A77 case - with 120mm fan per 3 drives.
The drives are plenty quiet - the fans certainly make more than the drives do - and they are only at 1000rpm - barely audible.
I have 14 drives active in RAID-6 with two hot spares off an Areca 24 port controller (12 drives seen by OS as 24TB).
HDTach nets me 400MB/sec xfer rate - faster than other servers I have with 6x Velociraptors in RAID-10. So, these drives are plenty fast.
Welcome to SPCR.
I have four of these in my file server (usually only one spinning though). The fan cooling them is an 800RPM Slipstream. The HDD is far from quiet (but then again, to my ears the Slipstream @ 12V isn't really that quiet either). I had an WD GP 2TB before (EADS, four platters) and it was way more quiet.
I still recommend the Samsung though, because of the low power consumption. Load during spin-up is also low, especially on the +5V rail, so my picoPSU 120W has no problem spinning up all four HDDs during startup. Three Samsung F3 and one WD20EADS was no problem either so I could perhaps even add a fifth F3 if I had the need to.
