SUMMARY: [Q] Can A5000 mix different size hard disk?

I got several answers.  Most answers are "YES".  You can mix different
size hard disks or different speed hard disks in A5000.  you may have
performance problem if you mix different spped hard disks for strip or
RAID.

To check hard disks spped use "iostat -E" or "luxadm".
