RAID and backup options

    Hey folks, I've just ordered a new workstation and I'm hoping for some advice in setting up a RAID.

    I have 4 identical drives on route but I'm not 100% sure what RAID config I should go with (Initially thinking RAID 5,6 or 10), also I don't have a dedicated RAID controller card as I'm not sure how critical they are and cost would be a concern.

    The workstation will have a SSD boot drive to hold the OS and working applications (3d modelling, photoshop and a few others).
    I'm planning to store the animations, textures and models on the RAID, I know write speeds will take a hit, but just how bad is it?

    Finally I'm completely clueless with regards to backup & archiving, would a separate NAS be a solution?

    Any advice or recommendations would be appreciated.

    Peace. :cool:

    Its hard to say as you have a bit of trade off whichever you go with.

    Performance wise RAID 10 would be the way to go. storage would be 50% of the sum of the drives capacity. 1 Drive failure can be recovered from 1 and in some cases 2 (provided they are not the same set of mirrored drives) drives.

    RAID 5 will get you more capacity for your 4 drives, 75% of the total capacity.
    Will cover you in the event of 1 drive failing.

    For best performance you would be working on current projects from the SSD (with a copy on the RAID Drives) so RAID 5 would probably be better for your setup.

    Regarding the backups an offsite backup like Mozy will cover you in the event of a disaster on your premises, the NAS will cover regular dataloss the RAID array cannot recover from.
