Is it possible to install a SATA3 SSD in a laptop if there was an HDD with SATA2 before?

Question

Hard disks

Hello. I have a laptop laptop HP Pavilion 15-p055sr G7W94EA. It has an HDD ST500LT012-1DG142 (500 GB, 5400 RPM, SATA-II) from Seagate. Judging by the AIDA64 data, my laptop uses SATA2 - it's just not clear where exactly it is used: on the HDD itself or on the motherboard. I decided to change my HDD to an SSD of the same size. Please advise which SSD should I take so that, firstly, it physically fits into my laptop and secondly, which port should the SSD go with. After all, new SSDs have SATA3.

Так все таки что у меня на ноуте : SATA2 или SATA3?

Answer 1

You can
sata compatible, but the speed will be less than sata3
size there 2.5"

Answer 2

Judging by the AIDA64 data, my laptop uses SATA2 - that's just not clear ..

in AIDA64 everything is clear:
- if you look in the motherboard block , then this is the parameter of the motherboard (controller)
- if you look in the block of the HDD itself , then this is the HDD parameter

Advise me which SSD should I get

like this

Form factor 2.5"

and about SATA, everything is also simple:
- as already mentioned by Dmitry , they are all compatible, they just work at the speed of the lower of the controller-device
pair - well, as you yourself have already noticed, there are no ssds lower than SATA III *
ps * type note - even if the controller is on a SATA II motherboard, you will still get a significant performance gain:
- SSD is a random access device, there is no time spent on positioning heads like a hard
one - a hard drive has a higher throughput at the "beginning" of the disk (on cylinders farther from the spindle) and gently decreases towards the "end" of the disk. and SSD has the maximum throughput on any fragment
- hard drives, especially 2.5", as a rule, even SATA II (and even at the "beginning" of the disk) are not able to fully load in speed

Answer 3

In your laptop SATA3(6Gb/s) and ssd will run at full speed.
But which ssd to take already depends on your budget and use cases. But even the cheapest TLC / QLC ssds will give a significant speed boost compared to hdd and live long enough to make the laptop completely obsolete.
