So I had RAID Failure in my primary drive this morning, the backup drive seems to be ok.  Unfortuntatly an iidentical drives is atleast 4-5 days aways.  There is a similiar drive by a different manufactor, with the same size and performance specs.  Do the drives have to be identical in everyway, or just in performance?

The make & model is not really the limiting factor.  This is how you should prioritize replacement disks .  (It is a given capacity on replacement >= current size)

1. Whatever is on the manufacturer's official supported HDD list.  Doesn't matter if RPMs or cache is less, it will have a minor performance, hit, but better to have a supported drive that is slower then use #2

2. If current disks are "enterprise" class, then you can go with 3rd-party enterprise class (appropriate for SATA).  Don't use desktop drives, you risk data loss.

3.  If disk is OEM drive, you must at least do some homework.  Example, if it is EMC, then they have special firmware, so you can't get a substitution.   Some vendors format the disks to something other than 512 bytes per sector, so unfortunately a universal answer is "it depends", not yes.

If you have typical low to mid range storage, then chances are good that a substitution is OK.

If you are using a newer drive with 4k sectors, don't mix that with one that can't do 4k sectors.
