I'm planning on building a home server using Ubuntu (most likely) which will be mainly used for backup, storage, file serving, and possibly video encoding. In anticipation, I got an Adaptec 2610SA 6-port hardware RAID adapter off eBay. I'm trying to figure out which RAID solution is best for me, and I've narrowed it down to RAID-5 and RAID-10. Performance isn't necessarily my biggest concern. I think as far as writing goes, I'll be limited mostly by my network speed. I shoot film with an HD cam, so I'll be storing writing a lot of large video files (likely around 10GB a pop) to the array. I'd also like to use the box to encode the videos into different formats, but I think I'll be more limited by CPU than anything when it comes to that. I guess my biggest concerns are space, reliability, and cost. I don't want to break the bank. Regardless of which route I go, I'm gonna buy 3 or 4 Hitachi 1TB Deskstars for the array, so it'll end up costing me about $300 tops. I'd like to get the most space possible. I'll be backing up my PCs and storing my music and film projects, so I want to feel secure with my data. I can always do a backup to a different drive outside the array (internal or external) for my most important stuff. What do you guys suggest? It seems to me that RAID 10 is most highly regarded. It's gonna cost more per storage space, but it seems to be more reliable, as I may be able to lose 2 drives but still be able to recover. Any input is welcome. Thanks!
