RAID 0+1 starting of as 0 then adding +1


Recommended Posts

Is it possible with my LP UT N4F SLI-DR motherboard using the Nvidia RAID that allows SATA II 3Gb/sec. transfer to create a RAID 0 array with the 2 WD HDDs in my Sig and then a few months later (when I can afford it) add 2 more WD HDDs identical to those and at that time rebuild my RAID 0 segment as a mirror onto the 2 new HDDs to create the +1 part of the 0+1. Or do all 4 drives have to be present at the begining and be set up all at the same time as RAID 0+1? I want the performance offered by RAID 0 but I don't want to lose 400+ Gigs of Data if one HDD fails. If this IS possible, is it easy to do? Who thinks this is a good idea? Who votes bad idea?

who could vote against it? I think it's a wonderful idea, if you have 4 drives, but you would only need a large third drive to do this, not neccessarily 4. Not sure myself if it would have to be done from the start or not. You could always just Raid 0 the four drives, then do an occasional back up on dvd!

hrmmm, lets see... 500 Gigs of RAID 0 divided by 4.7 gigs per dvd = 107 DVDs (give or take) now multiply 107 DVDs by about .50/each = $53.50 worth of DVDs plus ALOT of work. I think I would rather put the money towards extra storage.

Not to mention if you got the extra storage, you could just push a button to back it up again, vice paying the $50+ AGAIN so you can burn all those DVD's AGAIN when you want to back up your system AGAIN. My vote is for the extra storage.

Hell yeah! You think 5 years of downloaded internet porn will fit in an envelope?? I need some serious Gigage man! Not only that, I need all 500 gigs mirrored on a RAID 1. You've got to have redundancy for important data like that. You think I'm gonna risk titles like "ULTRA KINKY #79 - BOWLIN' IN HER COLON" on a drive crapping out cuz Western Digital's parts supplier shipped out a case of defective drive bearings??? I don't think so.

Why not just move to raid5? The SLI-DR can do that, y'know. It has Four Serial ATA ports supported by the Silicon Image Sil 3114 chip supporting RAID 0, RAID 1, RAID 0+1 and RAID 5. You'd lose a drive to the array but with 4x250 gig drives, you'd have a single "drive" present to the OS as 750 gigs and if a drive fails, you can run long enough to get a replacement.

 

here's a link to a nice article on the kinds of raid and their definitions.

the main reason for not going with raid 5 is because the sil 3114 chip doesn't support 3g/sec transfers. the NV RAID does but it doesnt support RAID 5 so my choices are - waste my SATA II's 3g/sec capability at 150mb/sec transfer on the silicon image RAID controller but gain RAID 5 OR Get to max out the SATA II's speed on the NV RAID with 3g/sec transfer but only be able to use RAID 0+1 not RAID 5
