Question Read speed in HDD

[Shervan360]

Hello,

Why has reading speed decreased over time?

Did you run trim before running the test? This is a SSD drive, right?
I'm not familiar with HD Tune Pro. I use CrystalDiskMark as I see it on sites all the time.

If by 'time' you mean the time it took to run this test: That's a perfectly ordinary performance curve because you won't ever get uniform performance right across the platter. The figures look reasonable too me too.

Hard disk drive performance characteristics - Wikipedia

This rate depends on the track location, so it will be higher on the outer zones (where there are more data sectors per track) and lower on the inner zones (where there are fewer data sectors per track); and is generally somewhat higher for 10,000 RPM drives.

Mikeymikec is correct! Your speeds look normal for a spinner.
