Is it possible to install in the laptop the SSD with SATA3 if this was a HDD with SATA2?

Hello. Have laptop HP Pavilion 15-p055sr G7W94EA. It has HDD ST500LT012-1DG142 (500 GB, 5400 RPM, SATA-II) Seagate company. According to AIDA64 my laptop uses SATA2 - that's just not clear where used: on the HDD or on the motherboard. Decided to change my HDD to SSD of the same capacity. Advise which SSD I should take to first, he physically broke into my laptop and second of all what kind of port should go SSD. After all, the new SSDS are SATA3.
P. S
The IDE controller on my laptop Intel(R) 8 Series Chipset Family SATA AHCI Controller
Also want to bring data from AIDA 64 on my HDD and the SATA port:

Properties of device ATA
Model ID ST500LT012-1DG142
Device type SATA-III
The parameters of cylinders: 969021, heads: 16, sectors in a track: 63, byte in sector: 512
The LBA sectors 976773168
The size of physical/logic sector 4 KB / 512 bytes
Multisector 16
Max. PIO mode PIO 4
Max. mode MWDMA MWDMA 2
Max. mode UDMA UDMA 6
Active mode UDMA UDMA 6
Unformatted capacity 476940 MB
Form factor 2.5"
Rotation speed 5400 RPM
ATA standard ATA8-ACS

Physical data disk drive
Manufacturer Seagate
The name of the hard drive Momentus Thin 500LT012
Form factor 2.5"
Formatted capacity 500 GB
Disks 1
The writable surface 2
Physical dimensions 100.35 x 69.85 x 7 mm
Maximum weight 95 g
Average latency 5.6 ms promotion
Rotation speed 5400 RPM
Max. the internal data rate of 800 Mbit/s
Average seek time 12 ms
The transition from track to track 1.5 ms
SATA-II
The speed of the data 'buffer controller' 300 MB/s
Buffer size 16 MB
The spin-up time 3 seconds

So all the same that I have on the laptop : SATA2 or SATA3?

Can
SATA compatible but the speed will be less than сата3
There size 2.5"
And my laptop is still SATA3 or SATA2? And could it be that my HDD is connected on SATA2 , and on SATA3 DVD or Vice versa? - laurianne69 commented on April 3rd 20 at 17:39

According to AIDA64 my laptop uses SATA2 - that's just not clear..
in AIDA64, everything is clear:
- if you look at the motherboard block, then this option motherboard (controller)
- if you look at the block of the HDD, this HDD option
Advise which SSD I should get
here's a
Form factor 2.5"
and about SATA is also simple:
as already mentioned by @Marcel.Pouros, they are compatible all, just work on the speed of the lower of the pair of the controller device
- well, as you already have noticed, ssd SATA III below are not*

ps * the type of note - even if the controller is on the motherboard SATA II you will still get a significant gain in performance:
- SSD is the random access device, no time-consuming positioning of the heads as hard
- the hard capacity is higher in the "beginning" of the disk (cylinders further away from the spindle) and gently declines to the "end" of the disk. and SSD throughput maximum for any fragment
- hardy, osbenno 2.5" as a rule, even a SATA II (and even in the "beginning" of the disk) are not able to completely loaded for speed
In PS, in the first two hyphens, instead of "SATA" should probably read "SSD". - roger commented on April 3rd 20 at 17:41

In your notebook SATA3(6Gb/s) ssd will run at full speed.

But what SSD to take depends on your budget and usage scenarios. But even the cheap TLC/QLC stsci provide a significant increase in speed compared to hdd and living long enough for the laptop is quite outdated.

Can.

what SSD can I take to first, he physically got into my laptop
To get that standing, measure with a ruler, and focus on size.

and second of all what kind of port should go SSD
Of course that in the laptop.

After all, the new SSDS are SATA3.
First - in what does the data interface to the connector? The second statement is incorrect - SATA3 long and hopelessly outdated and the new SSD with it not to release!

So all the same that I have on the laptop : SATA2 or SATA3?
You have there a long time outdated SATA3.
Although the choice of the SSD is irrelevant - whatever you have SATA2 or SATA3, without any difference.
this is when sata3 had become obsolete - if the new plug is not it?) - mark.F commented on April 3rd 20 at 17:45
@Hayden,
this is when sata3 had become obsolete - if the new plug is not it?)

It's not SATA3 connector and data interface. Communication Protocol and command set.
And connectors are different such as m2 plug for SATA3 is often used, there is a standard SATA connector, eSATA connectors have a lot common and popular connectors that vary in size and shape mainly. For example, in the laptops connectors smaller size, and a combined connector for data and power.

About obsolescence - now there are faster SSD drives which abut the clear limitations of the SATA interface - there is a huge delay.
So I invented a new interface in which minimized delay (latency) interface.
It is called Non-Volatile Memory Host Controller Interface Specification or the NVMe - gilbert.Hoeger commented on April 3rd 20 at 17:48
@Della, well, about nmve that poyantno.
But even with that it's sata interface, with a "connector" as a regular SATA not apnut, it remains - mark.F commented on April 3rd 20 at 17:51
