I am starting to put aside some duckets for an eRAID box for that great day when they allow expanded capacity (the S3 is full.. no room for suggestions). Does anyone have any sense whether RAID5 will work for this? We tend to avoid RAID5 in my business because of write bottlenecks and go with RAID1+0 -- but I don't want to waste that much capacity if I do not have to. I'm looking at a 2.5TB RAID5 array that might do the trick. if RAID5 is a problem with SATA drives, might I get past that by going to a SAS array with an eSATA connection? I don't want to spend more than $2-3k on this, but I will if it will make a difference. Noise is not a problem since it will go in an acoustical enclosure with it's own cooling unit, next to my home PC's SAS RAID arrays.
