". This firmware resolves the issue where a m4 SSD required restarts after approximately 5,000 hours of actual “on time” use. " - who here would leave their PC on for 5000 hours continuously? Im not gonna bother with this firmware upgrade if that's all it upgrades.
The issues are far more wide reaching than just requiring a restart.
The drive can effectively die.
And it's got nothing to do with the PC being on continuously for 5,000 hours, it's when the drive has been powered up for ~5,000 hours.
If you used your PC 10 hours a day then you'd reach the 5,000 hours in around 16½ months.
