I'm sure it is since the file system was created. Look at the year tho. It's about 11 years ago when I first built this rig. If I've only written that amount of data to my current drive over the last 11 years, the SSD drive should last for many, MANY, years, decades even. At this point, I should worry more about something besides it running out of write cycles. LOL I'd think technology changes will bring it to its end of life rather than write cycles. Eventually, I'll have time to put it to use. To much going on right now tho. Dale :-) :-)
