Go ahead - just try to guess which drive I'm using for my boot disk

[ggerke]

I'd been noticing odd occasions where my machine just seems to take a quick siesta. I'd guess the culprit might've been found?

So I'm thinking that now would be a good time to go get a replacement SSD and then just set this one aside so that when Spinrite comes out see what sort of changes take place.

@ggerke : (I put your results in a CODE block so that all of the columns would line up.)

You should run the benchmark with one of the detailed dump command-line options, like /1, or perhaps even /4. That will break down the summary results into a transfer-by-transfer detail.

So I tried rerunning on the various levels along with running it without options and got the following. With the changes in results for that 240GB SSD would that be an indication of the disk slowly losing it's mind?

I tried running Spinrite to see what level 1 would do but I got stuck on the discovering storage devices screen.

If you try running RS.exe with the "/1" switch you will get a more detailed report. This may show that there is one very slow spot which is dragging the averages down. We have also seen an effect where a disk is mainly empty, and it is suspected that some drives, knowing that the, say, 75% area is empty, respond much quicker with an empty block without doing an actual read.
