first question on superuser - pls excuse if asked elsewhere.
I have a Dell Precision 690 with one 73GB (15000RPM) SAS drive in it. Running Windows 7 (x64) with a bunch of apps means it is running out of space. I have on order a 147GB (15000RPM) SAS drive (same GB/s, same make) which I want to put into the machine.
Not knowing anything about SAS, do I need to replace the 73GB with the 147GB and restore from a backup, or can I put the drive in the machine and get the controller to treat the two drives as one large one? (The original paperwork for the machine says 73GB SAS (No RAID) if that is relevant.)
UPDATE: It has been suggested that I use the second disk for the data and keep my OS on the first. The biggest culprit after C:\Windows (22GB) is C:\ProgramData (13.5GB) and it would appear from this question that ProgramData can't easily be moved.
I would rather therefore just have one big C:\ drive - is this feasible with the two different sized SAS drives in the one machine, and can I do so without reinstall/backup-restore?
Thanks in advance.
PS Thanks to those that kindly migrated my question from serverfault.
I've given an answer, but superuser.com is the more appropriate place for this type of question. – ConcernedOfTunbridgeWells – 2010-05-21T09:59:51.550
