Well... it was more a choice between keeping and selling, but I get the idea.
Anyhoo, thanks for the replies. I'm feeling much better about this drive after doing some more reading so as long as I've got the latest firmware I should be A-OK. I'm still bummed about losing 8GB, but it's going to be a much faster SSD so I can live with it.
Reason I was mostly worried about the drive was I like to do my upgrades in cycles (kinda like Intel's tick-tock) and this one was a tock (new motherboard, and processor). I like to keep the changes at a minimum because I hate troubleshooting brand new builds.
