I have used a Kingston A400 120G SSD for about a year and 4 months as a boot drive(with a few other programs and smaller games that i needed to be faster) and its wear indicator is at 86%. And from what i have read it made me believe it is a pretty significant decrease in this period of time, but i was not too worried because the performance and Spare Blocks indicators are at 100%. ( It has lifetime writes of 9.56 TB with a power on time of 253 days)
Should i be a little more worried about this? And is the fact that it is basically most of the time only 8-10% free increasing the wear by a substantial amount?
