Hi:
Your model's maximum SATA speed is SATA II (3.0 GB/S).
A SATA III SSD will still work but only at the SATA II speed.
It will still be much better than a mechanical hard drive.

You're very welcome.
If your notebook has a Pentium processor, it should work pretty good. Celeron...I'm not sure.
I have an old HP 6930P business notebook with a Pentium P8700 processor, 8 GB of memory, and it runs W10 64 bit just fine.
I installed a SATA III SSD in it a long time ago.
It runs at the SATA II speed and is so much better than the mechanical hard drive it replaced.

by the way I upgraded my T4200 to T9600 processor. It run at windows 7 64bit very slow before upgrade and after upgrade the processor (nothing happen the laptop still running very slow like always not responding when I open chrome and the other software)

Then your PC has an even better processor than mine.
My notebook's service manual indicates the T9900 is the best one I can upgrade to.
I have no idea why your notebook would not run well with the hardware it has. That is very odd.
But a SSD couldn't hurt.
I am very happy with the way mine works.
Upgrade to W10 first before installing a SSD, and then you can clean install W10 on the SSD for free.
Here is how to get the free upgrade now...

Anytime.
Glad to have been of assistance.
You can get a decent performing 250 GB SSD pretty cheap nowadays...
I have this 500 GB model in my Dell desktop PC.
This is the 250 GB one.

The one I have in my HP 6930p is an old Intel 535 120 GB SSD, which they don't make anymore.
