I have a fairly new machine with two Samsung Spinpoint F3 HD103SJ HDDs on a GA-X58A-UD3R motherboard. I put the two HDDs in RAID. At first I wasn't able to install anything, because the RAID would fail, and the installation/operation that was currently on would end. If i tried anything, Port1 always failed. About 1-2 weeks ago, I fixed this by reinstalling the RAID. Until now, everything worked fine, however since about 2 days ago, I am unable to do anything, not even extract a WinRar - the RAID just fails near the middle of the extraction and it gives an "... is corrupted" error. I wanted to ask if there is any specific cause for this - whether if it is a faulty HDD or simply RAID is unreliable or something. Also, if it is possible, maybe you could tell me whether a RAID would make a serious difference (except for the ~double HDD speed etc) especially for gaming, since that is what this machine is primarily used for, since I am seriously getting tired from this because I just finished installing all my games and software . (And also a bit offtopic here - should I OC my processor? Is it a bottleneck, and will I also gain some noticeable performance by OCing?)
I checked the cables, they are fine. I checked for dust, and the HDDs are clean.
It appears that one disk is bad in the RAID0 - in RAID0, if you lose one disk, all data on both disks is lost. RAID1 (mirroring) is safer for data. More info here: http://en.wikipedia.org/wiki/RAID
Check both disks for errors.
I suggest RAID1 over RAID0.
Yes, your i7-930 will overclock well and you will see a performance increase in gaming, as well as in other programs. When you decide to OC, please read the excellent guides at this site (and other sites) by various authors, before you start OC.
A "quick and dirty" fix is to buy 2 x Western Digital
RAID Edition ("RE") HDDs, because they support TLER
in all RAID modes; and then demote your 2 x Samsungs
to dedicated data partitions; or, you could also try
formatting them as "dynamic disks" and enabling
an OS software RAID 0, which doesn't seem to need
support for Time-Limited Error Recovery (not that I
know of, that is But, you can't boot from such
an OS software RAID.
Two of the WD2503ABYX would be nice for your RAID 0 system partition,
because this RE4 HDD uses PMR (perpendicular magnetic recording):
