I'm trying to determinate whether my computer supports SATAIII or not: I'm currently using a 250GB Samsung SSD, but I'm sure I'm not pushing it to its full potential due to my computer's limitations ( It is a HP Pavilion Dv5 1102el).

I've been reading on the internet that the simplest way to discover which kind of SATA port I have installed on my system is by using Crystal Disk Info, whose results seems to be a little but confusing.

Take a look:

Both Sata 300 and Sata 600 are listed as compatible. :??:

Test your SSD with ATTO benchmark software.
ATTO uses highly compressible data to test Read/Write speeds. Highly compressible data is the easiest type of data for any SSD to Read/Write.

SATA 3 (6Gb/s) speeds are from 301MB/s to 600MB/s.
If your ATTO benchmark results are greater than 300MB/s then you know that your HP Pavilion supports SATA 3.

Well, guess I'm out of luck with my ancient laptop:

Is there anything I can do to improve those results?

Well, since I'm on a laptop, I guess I'd have to buy a new computer.
Btw, thanks a lot Dereck47 :)

The information shown by CrystalDiskInfo means the highest transfer mode your Samsung SSD is capable of is SATA/600 BUT it is using only SATA/300 mode on your system. Perhaps your SSD is connected to a SATA 2 port.

I bet if you run some SSD benchmark, you will not see sequential transfer rate higher than 300 MB/s. Most likely 280 MB/sec.

If you plug in your SSD to a SATA 1 port, CyrstalDiskInfo will show "SATA/150 | SATA/600".

Here's my results with ATTO benchmark software.

It seems like you're right :)
