I am looking to buy a small server for my home office. I do video editing, and currently using USB3 external disks is slowing me down, so I need a fast file server that I can use to store my live projects. (Note: I won't be editing using the server itself as I have my own workstation. It will only act as a file server)
I have two main questions about the hard disks. The first one is the difference between the 3.5" and 2.5" SAS drives. I am getting mixed opinions about the 2.5" ones regarding how they might affect the I/O speed and the performance. When I contacted the company that will provide the server for me, one representative told me to stay away from the 2.5, as they won't fit my needs. Another one said that it is okay to get them.
The other question I have is about the speed of these drives. Currently, I have enough budget to get the 3Gbps disks. I am not sure if that should be fast enough, or should I save a bit more and go for the 6Gbps ones. I read on some forums that the difference shouldn't be noticeable unless I am running a big server. Is that actually true?
