Right now I have a RAID 5 configuration on four 8.6GB hard drives. So I have a total of 16 gigs for my users to store their data. I only have a 20 gig tape backup drive. I ran out of hard drive space and started looking at NAS. So my question is, what RAID do you recommend that I use on my new NAS server that will be 480GB? I have autocad users who work on files off the server everyday? Also, what size tape drive do you think I should get to handle the new size of hard drive space?
The choice of a tape drive requires more parameters to factor into the decision. In general, if you are doing a frequent, regular backup, I would recommend something like an LTO drive which has a relatively high capacity and with data compression will be very effective for you. What's nice about the LTO drive besides its capacity and performance is that it is sourced from three different vendors that guarantee tape interchange. Other types of drives would work as well.
