@Tech2020, When you buy more storage price per GB should go lower...
Regardless of that, I really loved WD My Passport SSD design much better, not to mention it is smaller and also it uses standard M.2 form factor inside which is the newer standard that should replace mSATA.
I'm not saying I need an external SSD, just something I would try, and I would go for an expensive enclosure to protect that much SSD. Maybe something from Lacie. I would certainly sit down and do research first.
I let my office provide all my 'work' equipment (which these days amounts to a basic business class laptop, everything is in the cloud now or a least remote...). At home it is just a gaming build.
