I have a PS 100 with sata drives. The drives that Dell/Equallogic/3rd party sell specifically for the equallogic san cost $700 per drive, even though you can buy a sata drive for $100 nowadays. I've heard different things as far as using normal sata drives in it. Even one Equallogic tech support person said they would work fine. Others have very adamently said absolutely not. That the dell drives have special firmware and have been tested, etc. Anyone have any experience?
