Generally speaking, 24 reallocations in as many hours isn't a good thing. We shall see.
It might even be erase or program failures ala the M4, with no reallocations occurring yet.

The Mtron dropped out again today. Runs fine now but I had to restart the rig.

Okay -- now we have reallocated sectors. 335872 to be exact. If we multiply that by 512, we get 171966464 bytes, or 164MB. I'm not sure how that works out, because if you divide 335872 by the 41 reallocation events, you get 8192 sectors per reallocation. 8192 sectors is 4MB, so each erase block is 4MB? That can't be right.
Not, not good...
Increase count up of re-allocation sectors too more rapidly.
To predict. SMART spit out in the middle or long-term span?

565,248 sectors and 69 blocks. M3P MWI is down to 88.
I was hoping it would stabilize.

In two hours it went from 69 to 106 blocks.

MWI is now at 81, 106 reallocation events, and 868352 sectors. 424MB of spare area is now gone, but that's probably only 3% of the total allowed.
Like my vertex 4, the drive will probably stop working right at 200 odd reallocations.

The Mtron dropped out 1 time since last update. Runs normal now.
And another milestone. Today it's 1 year since I started testing :bday2: time to start year number 2 :D

Sorry about not doing more updates .... the sandisk is kinda being boring right now :) (but speed is up a bit)
324 reallocations now, 2,654,208 sectors, MWI = 51.
The M3P might finally make it to MWI - 1 (the hard way)

The Mtron dropped out again but runs fine now. Also there was a power failure sometime during the night so the endurance rig was without power for 6 hours.
I really like the way the M3P is going out; you'd think it would be dead by now based on the smart data, but it's working the way you'd think it should.
