Sadly, the WD20EARS and HD154UI drives are not the quietest seekers ever, even if they are huge and power-efficient. Especially compared to the flash drive in my laptop, on which I previously kept my torrents.
My RAID6 array:
- 2x Western Digital WD20EARS 2GB
- 2x Samsung HD154UI 1.5GB
Yes, I am running RAID6 on only four drives, but I very much have in mind the many tales of RAID1 / RAID5 arrays failing during a rebuild. I don't really care much about speed on this thing, anyway.
Also, I'm wasting 500GB of RAID-space with this configuration, which gives me an upgrade step to take before moving to a 6-bay NAS (though 3GB drives may be cost-efficient by the time I need to upgrade...)
