I have 3 4TB WD drives I want to put in a RAID1 array.

All enterprise class but two are WD Re and one is WD Se. I ordered the first two thinking 2 drives in the raid array would be sufficient but later decided its a long drive to the server so I would rather have 3 drives and ordered a third in accidentally did not get EXACT same thing. Would there be ANY issues mixing these?
using Linux MDRAID ? they'll probably be fine. they are all 7200rpm drives so should have quite similar performance. main difference is the MTBE spec
It's "enterprise" grade, where the two reds are "NAS-ready". In either case, the TLER should be 7 sec, so it should work. The ones to watch out for are the desktop grade, like the green (bleah!!!), which have a TLER of something like 2 MINUTES. That will *not* work in a server....
