Why is ssd speed cut?

Question

Iron

There is a SanDisk Ultra II SSD
. On the laptop it reveals all its declared potential, on the computer the speed is cut by 2 times.
As I understand it, this is due to the fact that the computer has sata 2, not 3?
In addition to changing the motherboard, can I somehow force the ssd to be completely overclocked?

Answer 1

As I understand it, this is due to the fact that the computer has sata 2, not 3?

Yes. Maximum 250-280 MB/s. The physical limitation of the interface is 3000 mbit /s.
Above correctly said about the purchase of the controller.
I have been sitting on SATA2 for a long time and, in principle, I am satisfied. The advantage of SSD is not only in linear write/read speed, but in access time. Do you often copy files back and forth? The maximum load is reading games and loading them into memory. And in everyday work, you will not notice much difference between SATA2 and SATA3.

Answer 2

Stick a Sparco sticker on it and paint it red.
Either buy a SATA III controller or a motherboard with one.
