I think the best way to check it getting some drives and testing it. No one would give you clear answer than your own empiric experience.

I found an answer on the vmware forums. Other guys have used regular drives and they worked.

So they went the way I suggested to you. Anyhow it will be good to know for others who reach the same dilemma.

I have a PS 100 with sata drives. &nbsp;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. &nbsp;I've heard different things as far as using normal sata drives in it. &nbsp;Even one Equallogic tech support person said they would work fine. &nbsp;Others have very adamently said absolutely not.

Equallogic drives

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.
