I have a decision to make for a fairly high IOPs database, which I am going to Virtualise.
At the moment the DB sits on our Dell SAN, using a 4 disk Raid 10 config, on 10K SAS drives.
This gives me more disk space than we need for the database, but a good level of redundancy.
I also have available, 3 15k SAS drives, which are larger in size. These could be configured in a RAID 1 array, with the 3rd disk marked as a hot spare.
My question is: would you see better performance in the RAID 10 on slower drives, or the RAID 1 on faster drives?
Thanks for your views!
