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.
