Normal drive lifespans are based on estimated usage of under 10GB written a day, far less actually, but with all this silent flushing, several times a day at the very least if not more, I’m not around to check or bother to watch the chart like a hound…we’re talking 100gb of data written if it just flushes twice. I’m sure its a mlc device so i’m not feeling so good about this thing lasting under these conditions. Also I doubt it has a sandforce like controller built in.
The SMART attributes will tell you the life time writes. Check the SMART to see how many lifetime writes have been made to the drive. That will show you how much actual usage has occurred on the SSD.
