how do i know if my pci ssd is going

There is no predictive value.

There are however apps that try to predict, by using a lot of value with predictive formulas.

These formulas are (and should be) different for different disks models. Thus a good app should have a large database of disks and of tested formulas for them.

A few years back I did a reasonably thorough testing of such apps and lost three disks in the process.

The one I use now is DriveDx from binaryfruit.com

LexSchellings:

When you say you lost three disks, was it just from the extensive testing done by the testing apps?

You can not give yourself points, although it works to create less attention from helpers 😁

Answer: No it was not because of the testing: these apps don't do tests, they read the S.M.A.R.T status and several other data from the disk. Then work their formulas.

I had two relatively new LaCie disks, and one a bit older Seagate: because of the prognosis I took 2 out for a while and let one LaCie in: it died two weeks later. Then the Seagate (external dies a month later, the second (external) Lacie died a day after that. I brought all back to the shop and got three new disks, no questions asked.

No I did not give myself points. And no I don't have any helpers.

I am not sure who clicked on Solved, but I can assure you it was not me.

Only the OP can select "solved". Lex was playing with you ... he is less kind to me in other areas of the forum so do not be concerned. 😉

Sorry, I thought I being accused of something.

Thanks for letting me know he was just playing with me. I feel better now.

Yes Kim, playing indeed, don't worry, no harm meant!

Don't believe steve359 he is playing me now 😁
