Looking after an SSD drive

I'm confused.

Did the performance of my 512GB Samsung 840 Pro actually get measured correctly, or did it exceed the expected value range of the test?

I suspect the "4K Read" number wrapped around the maximum number of digits allowed in the answer, as 25MB/s is obviously incorrect given the super-high values of everything else. So the whole READ-side set of numbers is probably missing 1000.

Or what??



(Lenovo W530 laptop, i7-3740QM, 8GB PC3-12800 memory, Samsung Magician running with just under 10% over-provisioning and "rapid mode" enabled)

Well thanks for the info.



Does that look okay??

Looks OK to me Trendy. Alignment OK. It's the access time that makes SSDs respond so much better than regular drives.

He was referring you to a program called SSD Life. There's a free version and a paid version. It makes an estimate of remaining life based on how much has been written to the drive. I have the free version on my PC and below is a screen shot, but I don't pay much attention to it. If your drive fails, it's not likely to be because of the amount you've written to it. With reasonable luck, it will last many years.

It says mine is supposedly good till 2282. It's 3 years old now, so 99% life remaining. But that's not very useful. It doesn't tell me when the drive might fail for other or unknown reasons.

Oh, I wish I hadn't seen this! I'm assuming the lower the Score: the better.

I'm especially troubled by the "103,424 K - OK". Does that say the SSD was not set up properly?

It seems to have been working just fine for over 2 1/2 years.

I'm not an expert on AS SSD, but I believe the HIGHER the score the better. Somebody please confirm or deny my hunch.

Which brings me back to my own 512GB Samsung 840 Pro results (which nobody's commented on), which appear to be EXTRAORDINARILY HIGH compared to others!



Are these numbers reasonable? VERY good (as I suspect), or just the opposite (please don't tell me this)?

High performance is also confirmed by HD Tune, so I guess the above AS SSD results must be correct.




The drive is on a SATA-III controller in the W530 laptop, replacing the original spinner. Brand new fresh from-scratch Win7 reinstall, producing 100MB "system reserved".
