SSD slow and recognized as ATA

[psmj15]

Hi, I'm new to Linux and programming. Since I installed an SSD on my laptop, it has shown issues with velocity, when I format the notebook, the velocity is like 500+ lecture, but after a few days, the velocity gets down to 130, like below

/dev/sda:
Timing buffered disk reads: 398 MB in 3.00 seconds = 132.57 MB/sec

This happened when I used Windows and now, with Linux, I tried to change the APM level with hdparm, but it says that it doesn't support it.
I just saw from hardinfo that my SSD has been recognized as ATA and not SATA (as shown in the image below) could this be it? the official website says the SSD is SATA, it's a KingsPec.

I found this:

Is Kingspec a reliable brand?

They're a knock off brand of Kingston that uses lower binned reject parts from the bigger manufacturers.

Among other such complaints and quality reports and reviews...

Now, as you say, it happened on Windows and it's now happening with Linux. That leads me to conclude that it's most likely a hardware issue, and not one that can be resolved with software.
