i had a lot of problems with my t7 and went through an absolutely excruciating return process. the bad service now makes me think twice about buying samsung products in general, but i had zero issues and was very happy with my samsung memory products before the t7.

i would get great read/write performance, but i think it had some bad blocks or whatever (confirmed but not apparently correctable with samsung magician) that id run into; when that would happen the drive would get a red blinkenlight, my pc would freak out, refuse to dismount the drive, unplugging/replugging was of no use, and the only temporary remedy involved a full reboot.
