My two WD10EARS are sitting in a MiniITX case with four hotswap bays.
The system runs 24/7, uses an Atom CPU (D510) and all filesystems on the
WDs are encrypted (LUKS on top of LVM on top of software RAID10).
Result:
- I don't care about hard disk performance, since the CPU is the
bottleneck for most IO operations. And my usage (audio/video
streaming, fileserver for one or two clients) doesn't demand much
performance anyway.
- I do care about power usage and the CPU actually demands less power
than all hard disks (4*3.5", 1*2.5" + slimline DVD) combined.
- I only care a little about noise. Inside this case, the drives need
active cooling anyway. Otherwise they would be running at >60°C.
What I want to say is: everybody has different needs and general
statements about the usefulness of specific drives are most probably
false in one or another usage scenario.
Regarding the 4k blocks: IMVHO, this time it's the free software crowd
that didn't get their act together in time. These disks exist for quite
a while now and even if some of them report the wrong block size, the
tools don't even automatically do the right thing for disks that don't.
