    RAID

    Hi all, I have 4 HDD's (2 x 40Gig & 2 x 80Gig) and a RAID equipped Motherboard. The HDD's basically have backup's of my "doc's & Settings" and images of CD's. The reason for this amoungst others, is so I can install a new computers' software across a network. given that I only use the HDD's as a storage medium, which RAID setup would be best for me? the book that came with the Motherboard is less than helpful.

    Thank you in advance
    Robert

    Re: RAID

    Hi Robert,
    My first question is why do you actually want RAID? (Just because you can? <img src=/S/grin.gif border=0 alt=grin width=15 height=15>) The answer to that will to some extent determine what RAID level you want. Your choices are relatively limited given the disks you have (unless you're willing to sacrifice half the space on two of your disks) so I think your choices really are RAID0 or RAID1. Given the disks you have and the fact that from what you've said I would assume reliability rather than speed is the key, I would go for 2 RAID1 arrays. Note that this will leave you with 120GB of disk space rather than the 240 you paid for, but if you need the reliability it's probably your best bet.
    Hope that helps.
    Regards,

    Re: RAID

    RAID-5 is fairly typical. It splits the data to be written into two chunks, puts one chunck on disk1, one on disk2, and a check bit on disk 3. If any drive fails, replace it, put an identically sized partition on it, and run the controller's restore routine to rebuild the missing data. The catch, before you ask, is that all three partitions must be the same size, and for reliability's sake, on different physical drives.

    Re: RAID

    thankyou Rory Dean and jscher2000 for your posts. Apologies for my tardyness in responding, work gets in the way at times! have decided to go with Raid 1+0 as I want access to that much space. jscher2000 i had a read through the archives and that particular thread prior to posting and found it informative on what most other raid types are capable of but didn't address my simplier needs. once again thankyou for the input.

    Robert
