I have a database on RAID 0 which I conceed is a bad idea for a database.
I want a RAID 10 setup - which is a second RAID 0 that you mirror (RAID 1) .
Question - at the moment my two RAID drives are Western Digital Raptor 10,000 rpm which are a little on the costly side.
If I purchase another two drives to make RAID 10, do you recommend that I go for drives of the same speed - or can I save a penny by going for cheaper drives.
What I am thinking is that if either of the Western Digitial Raptor drives fail, I can run on the slower drives for a short period until I install and restore the Western D.Raptor array.
However, performance on-going is key and therefore if purchasing slower drivers will impact performance of the whole array - I dont wish to go that way.....
