Empirical rating based on...stars and unicorns? Glitter stickers?
I'm all about real-life reviews and impressions of products but you're not exactly giving folks a lot to go on. Perhaps a sentence or two regarding read/write speeds, TRIM or stability/reliability might be a wee bit more useful than "this drive is awesome let's rawk HOOAH!"
I'm at work, give me a break lol
However, my ratings are based on my observations from using the three in my Sony VPCSC laptop, as system drives with negligible data on another drive.
BTW, I still have the stock firmware from when I purchased it early 2012. Good luck!
