I want to upgrade my laptop by change the HDD to SDD. The question is my laptop is platform SATA and SSD is SATA III. So, are the SSD SATA III can support my laptop platform (SATA) or not?

This is my laptop model:

Samsung NP-R440-JT01MY

SATA III is backward compatible with SATA II or SATA I ... just like USB

so, in easy word, the sata can support sata iii. am i right?

It is the other way around. The SSD with SATA II itself is backward compatible. If your laptop is SATA I, the the SSD with SATA II will perform like SATA I SDD

that's means my laptop is sata i, then if I installed ssd that itself sata iii, it will perform same goes as sata i, right? never change the performance right?

so, it useless if I change to ssd. better change new hdd one

I don't know what you meant by this. I guess you confused.

IDE (Integrated Drive Electronics) was the original name, then they standardized on ATA (Advanced Technology Attachment) as being a broader standard that included additions like CD-ROMs and such. When SATA ( Serial ATA ) came out, people started using PATA (Parallel ATA) to refer to the older parallel connected bus (those using ribbon cable), to be more specific than the term ATA, which can refer to either. Both are part of the ATA standard, and use the same logical command sets, but SATA obviously has a different electrical interface. Both types of drives (SATA and PATA) are IDE devices.

I think there is no more old IDE (PATA) hardisk in market. My old laptop at home no more hardisk for replacement. Buy used one maybe is the only choice. for desktop PC, you can buy adapter to convert to PATA but laptop has no space for that.

So, most likely all new HDD has SATA III interface support but since your laptop is SATA I, so you will get the SATA I performance. Therefore, if you can find the SATA I hDD out there, it would be likely cheaper than the one that support the SATA III

Whatever SATA version your laptop have, when you installed SSD to it...the responsive of system is much much better than all HDD out there...

now I get it. If I used ssd sata iii, I only get sata i performance sicce my laptop platform is sata i. By the way thankz for answering my confusing questions 😁

owh, I thought when change ssd it would be the same as sata i performance. so, it will enhance slightly in performance if I used ssd sata iii no matter what my platform sata i have

SATA and PATA is the interface performance. Now the SSD, HDD or SSHD is another story. This is the drive hardware performance. HDD is traditional drive using magnetic plate with moving mechanical parts. The SSD is solid state drive using technology something like your thumb drive with no moving part. So, SSD is "very" fast and noticeable speed advantage over traditional HDD. SSHD is Solid State Hybrid Drive, taking advantage of both technology. You can Google to understand more

Zot is correct. SATA is only interface. The version is indicate the speed capping.

So, with your laptop SATA1 port version, install the SATA3 version SSD and the max speed you will get is ~150MB/s even the SSD spec is up to 550MB/s. But still superior to normal HDD speed (~50 to 80MB/s i think..)
