[SOLVED] SSD 137k+ Power Cycles?

[jacogoodman]

I've had a Samsung 850 EVO 500GB 2.5" sata SSD plugged into my xbox for the past year or so. It's been in an external enclosure and I put games on it that could benefit from faster load times and such. However, I'm looking to sell it so I checked it's lifespan through a drive monitoring software. It said the SSD has gone through 137,502 power cycles! I'm absolutely lost. I have no idea why this number is so high. The total amount written is only 5.2 TB and power on hours is at 4,303. Also, I do not sleep my xbox when I'm not using it, I completely shut it down.

Has my xbox been turning it on and off repeatedly for no reason? And I have no idea if SSDs have a max power cycle endurance, so should I be worried?

Can you show us CrystalDiskInfo's SMART report? It should be possible to determine how many power cycles the drive can execute before it hits the threshold.

No I cannot get a report any longer, but Samsung surely put the power cycle threshold for this drive somewhere on the internet. I'll search around, thanks.

AIUI, the normalised value of the Power On Count attribute drops from 100 to 99 after the very first power cycle.

Here is an example where the attribute has fallen to 96 after 3782 cycles:

Therefore the number of power cycles before the drive loses all 100 points is somewhere between ...

3782 / 4 x 100 = 94,550

… and ...

3782 / 3 x 100 = 126,067

Therefore the rated number of power cycles, at least for SMART purposes, is probably a round number of 100,000.
