This should be a fairly easy request for a check and advice. In-depth answers would help on any possible issues.
I've just bought a DG45FC.
Purpose and setup: Hosting twin 2GB data drives as a file server. OS will be WinXP SP3 (32 bit). It won't be doing much else. Other hardware: 2 GB ram, DVD, and a third (2.5") HD to act as the system drive.
While waiting for the PSU, I would like to double check two areas new to me:
(a) drivers and installation:
I'd probably like to be using AHCI (no reason not to, probably more efficient). But this needs the extra drivers during XP install. Not inclined to use nLite (I customize my install folder and nLite seems to try and alter it so it doesn't always work afterwards) so I'm not sure how better to install Windows.
Or if I can't:
- What are the issues with sticking with IDE mode and how badly will they affect anything? Or can they be installed afterwards somehow and then the BIOS changed to AHCI as well?
- Or, is there a USB floppy drive that definitively is known to be recognized by XP install (tried one listed at MS website, no go)
(b) RAID 1/Rapid Recovery:
I'm not clear on the difference between the two or between RRT and ordinary RAID1 (obviously RRT is a RAID1 variant). The data drives are big and the data would be a pain to lose. I've done the usual - different batches, etc - and considered the risk that some virus or PSU issue might fry both drives simultaneously. What I would like to protect against is data loss due to an individual HD failure, or corruption of stored data on an individual HD over time.
RAID1/RRT seems an ideal way to do this, but I haven't needed to use RAID before so I have a few questions.
- Can the ICH10 be configured to run 3 or 4 drives as a mixed system: - a system drive, a possible spare ("temp") drive, and 2 drives mirrored/RRT'ed?
- Should I use RAID 1, RRT, or just operate it as 2 drives and use backup/sychronization software between them? Any differences or things I need to know about RAID1 and/or RRT to make a decision?
- Under RAID1/RRT, is data compared on read to ensure fidelity, or is it just mirrored to both and on reading grabbed from the primary unless the primary gives an error?
- If I use RAID1/RRT, is there a way (software or otherwise) to tell the system to compare the two and report any data differences it finds? If not, how would I check that no data is corrupted between the two of them? (If RRT exposes the second drive as read-only to run a file compare program that would be one way)
- How is data speed (MB/s) affected under RAID1/RRT, compared to using a single drive without RAID/RRT?
Thanks for any input on these!
