Needed a reliable fast performing NAS for work for a new project we are working on with a 2yr duration and expected 10-15 user accessing files simultaneously. I made some recommendations to our lead IT manager and surprisingly he agreed so we purchased:

and four of these: http://www.bhphotovideo.com …am_851_evo_250gb_2_5.html
Qnap TVS-471 w/ four Samsung 850 Evo 250GB drives.
Set the machine up for Raid 6 so we have 447GB of storage (we expect to only use under 100gb) but the fact is we now have dual disk failure SSD performance and we also have a standard 500GB external drive plugged into the USB 3.0 slot that we are using to backup the Qnap. We also have the corporate servers backing up the drive remotely. I think as far as redundancy we have things covered.
Now... since we will be in an office productivity with multiple users we picked the SSD and boy let me tell you.... copying the server files over which was 20gb of data with all sorts of spreadsheets, documents, large navisworks model files and such the transfer across a gigabit network was smooth along at 45MB/sec which I though was impressive. We actually have all 4 lan ports connected and transfering a large 1.5GB file over flew at over 200MB/sec
Without a doubt this machine is flat out fast and awesome. $1700 is the money we spent but it was through our company and we are doing this in lieu of an actual server which we were quoted $5k w/ a 5yr service plan. So in the end the management feels good about the savings and I feel great about being able to work directly from the NAS with multiple users w/o hiccup.
Just wanted to share.
