I currently have a two disk raid1 array (2TB in size) that is the storage for my LVM but is running out of space. I want to add two more drives to bring available storage to 4TB but I also want to convert raid1 to raid10 to increase the performance of my storage. Here's how I did it.
Since it's been two years since my last raid cost analysis, I figured it was about time to do another one.
Goals:
- increase my storage. Currently 1000GB using raid5 (3 x 500GB drives)
- preferably only use 2 drives as it costs money to spin an extra drive
- not spend too much
I just upgraded my servers raid5 drives and figured I'd post my cost analysis. Put that way it almost sounds scientific…
