Strange S.M.A.R.T. readings on SSD

[doinstuff]

I did something dumb and bought a used mSATA SSD. It's a Micron MTFDDAT128MAM-1Jt. When I first got the drive I installed Micron's Storage Executive software and I see a very high Unaligned Access Count, High erases, but low Power On Hours. Also it showed 1% of the SSD's life had been used. It's now at 14% used and holding, I'm watching waiting for it to die...

I thought I was going crazy when I would check the numbers, so I took a screenshot so I could compare. After 4 days and 20 hours the Power On Hours have gone from 3596 to 3616, I have cycled the power fully off 3 times and the Power Cycle Count has never moved from 1899 since I got it. The Unaligned Access Count has gone from 7,443,194,512,846 to 7,499,029,677,521 even though I have checked that it is aligned (I read several articles, used a couple tools I don't remember which ones, checked msinfo32).

What would cause such strange readings? Is it just because the drive is starting to die or something else?

doinstuff, go ahead and run Seatools on the mSATA. It will tell you want state it is in.

Seatools is useless here. When it comes to SSDs (well, HDDs too) each vendor has their own S.M.A.R.T. attributes and there is no real standard.

I re-installed Seatools just for you. The drive passes a S.M.A.R.T. btest, Drive information shows Power On Hours of 3634 which matches the Micron Storage Executive software, but Seatools does not show Power Cycle Count, for some reason shows Security Mode "Supported, Frozen" and really no other useful information.

I discovered the "Save to File" button in SeaTools, here is that readout today:
