One user reported how SMART data from both Samsung Magician and third-party tools had dropped to 99 per cent
“For the record, I have other Samsung SSDs with over 40TB written and still at 99 per cent health 1.5 years later, so I knew this was not normal. Within another day or so, it had dropped to 98 per cent, by this point I'd not even written 2TB to the drive. Fast forward a couple more days and the drive health were sitting at 95 per cent.”
There is a lengthy thread over at Overclock.net about it but users who send their ships back are finding that they are being returned because they do not have a defect.
Any testing done on returned chips seems to be limited to reformatting and resetting to factory defaults and there is no word of any new firmware in the works.
