Now, HDDs - don't work with loads of desktop PCs at work any more, so I don't have an upto date feel for what's good and what's crap based on numbers.
This will be a 24/7 server - light load. It can take 4x 3.5" SATA disks in RAID-5 config.
Normally I would stump up the dosh and put in something like:
WD 2TB RE SATA 6GB/s 7200RPM or Seagate 2TB Constellation.ES.2 Both 5 year warranty which is usually the indicator that they are any good.
The other option that caught my eye might be to stick some SSD hybrids in:
Seagate 2TB Desktop SSHD SATA 6GB/s 64MB 3.5" 8GB SSD Cache http://www.dabs.com/products/seagate-2tb-desktop-sshd-sata-6gb-s-64mb-3-5--8gb-ssd-cache-8XSM.html
Interesting. 8GB SSD cache. Bit cheap, but 3 year warranty so surely not *that* bad? Anyone used this particular hybrid before?
