I just upgraded my servers raid5 drives and figured I'd post my cost analysis. Put that way it almost sounds scientific…

Goals:

  • increase my storage. Currently 500GB using raid5
  • preferably only use 2 drives as it costs money to spin an extra drive
  • not spend too much

I'd have preferred going with only 2 drives (raid1) but the cost per GB is just too high. Possible choices are in green, but I went with the blue one. All prices from the only computer store in Calgary, Memory Express.
