To RAID or not to RAID
I am currently working on a configuration for a Precision 690, which will be used for CAD and other OpenGL apps. I can't wait.
The configurator wants me to choose whether "All SATA drives, Non-RAID, 1 or 2 drive total configuration," "All SATA drives, RAID 1, 2 drive total configuration," and so on. All of these options are no charge.
I understand that choosing SATA or SAS is a one-time decision. But, I'm wondering whether the RAID configuration and the number of drives can be changed later?
For example, could I choose a non-RAID 1 or 2 drive config now, but change later to a RAID 4-drive config later?
And if so, how? Do these options require changes to BIOS or other?
Thanks for any guidance.

Certainly, you can change the RAID configuration later. Keep in mind that this may be somewhat involved. You can migrate from some RAID configurations but not others. Worst case, you might have to wipe your drives, create the RAID configuration and then reinstall.
FYI, the internal SAS controller offered on the 690 only supports RAID 0 (Striping) or 1 (Mirroring). They do offer an upgraded RAID card that supports RAID 0, 1, 5, 10.
