In the past, several SSD manufacturers had bugs in their firmwares. So to be sure that I can fix such issues with a newly bought SSD, I need some secure (and somewhat easy) way of updating the firmware.
I don’t need to do the update on my own Linux installation. A bootable ISO would be fine, too.
Which manufacturer has some well supported way of updating SSD firmware, even if I don’t have any Windows installations left?
You’ve been lucky, then. Some popular SSDs have had firmware that actively corrupted data or burned through the flash cells incredibly fast.
