For NVMe, if you get the SMART data with smartmontools/smartctl, you can inspect Percentage Used.

"Percentage Used: Contains a vendor specific estimate of the percentage of life used for the Endurance Group based on the actual usage and the manufacturer’s prediction of NVM life. A value of 100 indicates that the estimated endurance of the NVM in the Endurance Group has been consumed, but may not indicate an NVM failure. The value is allowed to exceed 100."

for SATA/SAS SSDs, there is "Media_Wearout_Indicator" which hasn't been a particularly reliable indicator in my experience.

CrystalDiskInfo[1] can be used for this purpose over on Windows. Some vendor-provided utilities like Samsung Magician will also provide this data with appropriate drives.

Only if you need a fancy GUI or guide some non-tech person to read the values to you over the phone/IM.

Otherwise just use win32 port of smartmontools.
