My question:
Is there a downside to configuring HD's as RAID in the BIOS, when there
are no member disks?

Background:
Computers use 2 or 3 SATA hard drives, setup as Native-IDE, or RAID 1 -
ie: A System HD & 1 or 2 Data HD's.

Our company uses computers as part of the medical systems that we sell.
Some of the systems specify using RAID 1 for the Data drives, but some of
them don't. We save a sysprepped image of each system, & then use it as
the base for the setup of each computer. Because some of the systems
don't require RAID, if we don't setup the computer as RAID in the
configuration, & instead configure it as Native-IDE (or Legacy), we can't
use a RAID image to install on the hard drive.

If we do use a RAID image on a Legacy or Native-IDE system, when the
system attempts to boot up for the first time it just goes into a
continual boot & reboot cycle, & never will actually bootup.

Because of that, I am proposing that we setup all computers configured as
RAID systems. Some of the computers won't actually use a RAID aray (no
member disks), but will be setup that way.

I would appreciate any info one could shed on this matter.

Thanks guys

Hi :thumbsup:.

A RAID-1 is nothing but a fancy/easy (depending on perspective) way of backing up system data. It's not the only way, it may not even be the best way...depending on systems, architecture, etc.

I suppose that it's more efficient for various operations, compared to other techniques for duplicating/saving file data.

Perhaps this link will help clarify what various RAID configurations are and are not,
