Hi, I'm hoping someone can help clarify if I need to be worried about my SSD's health or not.

I checked HWInfo64 earlier and saw these results: View: https://i.imgur.com/H4cthOS.png


Thinking that this might be an error with HWInfo, I downloaded the Kingston SSD Manager software to try checking the drives health with that, these are the results from that: View: https://i.imgur.com/r39zUmR.png


I am a little unsure how to read the data, or which software to trust. Any help would be much appreciated!
 
The Normalised values of the SSD Wear Indicator attribute are 4 while the raw value is 96 (= 0x60 in hexadecimal).

I believe this is telling you that the total amount of wear is 4%, and the total life left is 96%.

I say this because the average erase count is only 32 (= 0x20). It would appear that 1 percentage point of wear equates to 8 erase counts. This then suggests that the SSD is rated for 800 P/E cycles.

Assuming a write amplification factor of 1, this would suggest that the TBW spec would be of the order of 220TB.

How old is the Kingston SSD and how is/has the drive been used? Environment?

Was the drive purchased or obtained new, used...?

Go to Disk Management, expand the Disk Management screen to show all drives and drive information.

According to teh device specification, if you look up on kingston website you will find this:
Total Bytes Written (TBW)4120GB: 40TB
240GB: 80TB
480GB: 160TB
960GB: 300TB
1.92TB: 600TB


Yours is 240GB so it can endure 80TB of writtings, you got 7TB right now, 7%, so yeah, it is very healthy.
