SanDisk is a solid brand. I got a Standisk 250gb SSD installed in my Dell latitude two years ago that I've had since 2011, got it brand new. Hasn't failed me yet and still runs super freaking fast, as fast as when I first got it put in. Nothing but positive for me but then again all I do on my laptop is play games in my web browser, casino slots and what not, stream live sports, and browse the web/social media. Don't know how it'd do running a BTC node.
