Hi, I'm pricing out a new 66TB storage system as follows:
- Areca ARC-1882-ix-24 - $1550 w/ 4GB RAM and cables (could go with a cheaper 1880 or 1680 instead..)
- 25x Seagate Barracuda XT ST33000651AS 3TB drives, in RAID6 - $229 each
- Norco 4224 case - $430
- SAS cables
- motherboard, CPU, PSU, etc.
Wanted to run it by the community for feedback and whether there are other options at similar price points I should consider. Any comments / suggestions? Any estimates on what rebuild times will be like?
One concern I have is the Norco backplanes only do Sata 3g. Will these disks be able to saturate the backplanes? If so, I'd consider ripping them out and just connecting the PSU / controller to the disks directly w/ SAS-SATA breakout cables.
Reason for the Areca card is I already have a couple ARC controllers and like to keep similar equipment laying around for backup / interchange purposes.
I currently have a 20-bay Norco 4220 with an ARC-1880 and 1.5TB Seagate Barracuda plain old 7200rpm consumer grade drives in it. Been okay over the last two years, although a drive "dies" (< 10% health in Hard Disk Sentinel, primarily based on # bad sectors) every few months and write speeds across the network are slower than I'd like. Figured I'd spend the extra few bucks to step up to slightly better drives this time around especially with the 5yr warranty. Want the extra one on hand so I can swap out immediately when needed.
Also anyone know if Hard Disk Sentinel can see behind the newer Areca cards?
