What is the problem with low speed SSD?

Question

Solid State Drives

I purchased Kingston UV500 form factor 2.5
I decided to conduct tests and compare with the results from the reviews
I checked that TRIM and AHCI are enabled
The disk is absolutely empty and not loaded, I plan to launch the OS from it in the future
As it turned out, some block recording lines do not correspond to the lines from the reviews
When I took into account that the
benchmark versions are different and, for example, some changes took place in the 6th version of CrystalDisk




.



so it was changed in version 6)
Total: 139-159 vs 304-324
If we compare the AS SSD benchmarks, it turns out that only Read 4k-64Thrd > 121 vs 292 suffers greatly

Your test speed is normal.
As for the rest, they will never be identical, everything is within the margin of error.
Testing was carried out on different systems - the processor, chipset, etc. are gradually affected there.
And the data for testing is different and the disks are different.

It really depends on the data. This is reading with a long queue. It depends on how the data is located in the queue and how the data is actually located on the disk. That is, there is a high chance factor.
