I have 200 users all at one site. No big file thrashing, just excel and word files. I need around 5TB of redundant storage. Preferably SATA drives. I also would like redundant power and gigbit ethernet. Can a few people send over some links as suggestions? Cheap and reliable is the key. I have a nice backup solution in place which can back it up nightly I just want RAID5 so I can swap out bad drives as needed. Thanks!
