I have an old Dell Poweredge 1950 that for its age, is still fairly decent. I would like to Frankenstein it as much as possible. It has a Dell PERC 5i RAID controller and currently has 3 drives in RAID 5 (not something I setup). These drives are 10k RPM SAS drives. I would like to add more drives to it, but I do not have anymore 10k SAS drives, just a bunch of SATA 7200 RPM drives. Can these be added to this RAID card, and used at the same time to create a new RAID array? I am guessing no, but I thought I would inquire.
