Thanks Glen,  They are different speeds and different sizes. I am replacing a 320GB 5400 RPM drive with a 500GB 7200 rpm drive. I have never mixed drive sizes as well in a clariion enclosure.  Thanks! Admingirl
Hello,  I lost a 320GB SATA drive.My enclosure is full of drives with that speed. EMC support sent me a 500GB sata drive and mentioned that I should be able to replace that drive. I am running FLARE code 3.26.080.5.031. I have never seen a clariion of that model type have mixed drive speeds in the enclosures.  Thanks in advance!  Benita
Can you mix drive speeds (SATA drives) in a cx3-80 enclosure
