    At this point, Western Digital may be the only brand of SSD left that hasn't failed on me. I just submitted my second Samsung drive for RMA. At least Crucial was quick to replace their failed drive, but only WD has an unblemished record (no failure within 3 years of purchase) from the 8 or so brands I've tried over the last decade. (To be fair, I haven't quite owned my Sabrent 3 years yet, so no judgement yet.)
