This thread prompted me to DL the Intel Drive Toolbox and check my Intel 750 Series 1.2 TB PCIE3 SSD C: drive (still only a quarter full!).
Estimated remaining life appears to be ~90% (89%?) which I guess is good given that the drive is now over 3.5 years old (remaining life ~30 years !!?? 😅). Assuming I am reading the bar graph correctly!
Some stats intriguing relative to those posted by K8Toledo. Possibly I am misunderstanding some reported values, though.
Power on hours for me is only half at 16281 but power on count is almost double at 17074. Latter figure looks odd as normally the PC is turned on and off only once a day. The reported figure suggests about once an hour, which does not make sense?
Also puzzled by my 'Data Units Read' figure which at 331.67 GB seems very low for a C: drive? 'Data Units Written' is higher at 1888.34 GB but still low compared to K8Toledo's values. Ratio of Host Write Commands / Host Read Commands is even higher, more like 12. Yet higher up in the SMART details 'Timed Workload - Host Read/Write Ratio' is showing as 17 (seems to contradict the preceding data???). At least all but one of my error/fail counts are 0 (Number of Error Info Log Entries = 1).
