I have a raid 5 config of 8 identical drives.

Now a drive has failed and I need to replace it.

the original drives are seagate 2tb 32mb cache, 5900rpm.

Can i use another seagate that is the same specs, but a different model?

Original drive:

new drive:

Baracuda are only really suitable for desktop RAID, not for servers.

Just to add on to @Sjizzel;

The drive doesn't even have to be from the same maker; problem occur when you start changing specs. For instance, if you put at 7200RPM drive in a RAID5 as a replacement, the controller will run the RAID at the slowest spindle speed which would bring that 7200 down to 5900 in this case. Another case would be that there is a different sized cache on the drive; for instance let's say that instead of a 32MB cache there is a 16MB cache. You would suffer a little from performance issues, but you wouldn't really notice if it's not in a high-use capacity. The overall thing to not chance up is the drive size as this can and usually does cause problems.
