Why, and what do we need

Thought I'd share this with everyone, it may be interesting for some (though for most, a bit of an overkill). I wanted some more storage available on my Firebox x750e, but didn't like the idea of installing a very expensive IDE SSD (with a very low throughput), or a bigger CF card. CF card just aren't built for a lot of IOPS, and wear levelling isn't really strong on those things either. I wanted a solution that will last for years. I decided a regular SATA would be perfect (although a little expensive).
