Pre-sales focused exactly on my needs - RAID was new territory
Setting up a dedicated slide/film/photo scanning suite for my personal archives. I know I needed the best storage I could get, so I opted for a simple beginners RAID solution. Pre-Sales set me right so I purchased a SSD solution. Setup a cinch. Now I am ready to work hard and not loose my files. If I was home, not an ocean away, I would add so pics.
I would recommend this product to a friend!
