Strange experience with Samsung SSD

One's a 500 the other a 250, not the same.

Then the 500 should be faster than the 250. Speed can be affected by the amount of free space left on the drive, but I think that only becomes an issue once you get below about less than 10% remaining space. Are they both running the same firmware?

Did you try benchmarking in safe mode so you can narrow down the errors

Did the benchmark in safe mode.

READ was 2249, in safe mode it is 549
WRITE was 2381, in safe mode it is 502

Safe mode is disastreous. Logical as in safe mode probably needed drivers and programs will not be loaded.

Both running the same firmware. Installed the latest version on both.
250Gb has 85% free space
500Gb has 75% free space
So space in not an issue

I remember that in the beginning the 500Gb was much faster. Samsung thinks that the SSD got messed up. They suggest to format the SSD again and reinstall all the software.

I would like to do the following:
  • make a new backup with Acronis
  • format the SSD again
  • reinstall the disc image from Acronis
Did this already before with HDD. Works.

Only question is: how will Acronis put back the image.
If it puts back the data at exactly the same place it might be useless as the SSD will be like before. Unless the format repaired the messed up blocks.

From what I understand, Acronis makes a backup, but is skipping all the empty blocks. So the image has no empty blocks anymore like the original SSD.
If I put the image back on the SSD logically all the empty blocks will be gone.

A picture will clearly show what I mean:

If you are comfortable with taking the disk out of laptop you should benchmark it in your desktop as a 2nd hard drive before you waste time with format n backup

Open the laptop is a terrible job. Did it already to clean the cooling.
Format and backup is much easier. Will think a few days what I will do.

You could buy another SSD, equal size or larger and simply clone it. I did this about a month ago using Linux Clonezilla. It's not a matter of how the data is laid out. Actually the SSD firmware will periodically move data around even if you don't do anything...or at least that's how it worked many years ago, maybe the technology has changed. I'd post this question on a more hardware-oriented forum like Linus Tech Tips or HardOCP. Then buy a $7 drive enclosure and use the old drive as a backup drive or sell it on eBay :-).

Yes, maybe better. Clone it, and reformat the old drive to see what that will give. Cost is around $75 so that's not the problem.

But opening that laptop again... :mad:
