I need to kit out a dev-review notebook with a few VM's on it. I'll need about 600Gb min. I don't usually expect more than a VM to be in use at any one time. I'm not really into spending a lot for this (e.g. I'm getting a bottom-feeder £700 notebook for starters), but at the same time pretty everything else I have is SSD and when I pick up other people's hybrid or HDD machines I just feel like I've gone back a decade, so I'm looking for SSD response in general. How does the Black2 do in a VM-heavy situation? Am I better off in terms of frustration avoidance with an M500 / 840 Basic, or is the Black2 sufficiently plausible?
