SATA 3 SSD HDD in Compaq Presario V5202TU?

[vakul]

I have a Compaq Presario Notebook Model# V5202TU.
The Laptop is in fine condition with 2 GB DDR2 633 MHz and hence i intend to install a 120GB SATA III HDD in the same for better performance.

Is SATA III (6 GB/s) backward compatible with SATA I?

Please help!

Generally SATA III is compatible with SATA II but to be honest I have never tried to install a SATA III device into a SATA I port so I cant say. I know some SSDs have issues with older SATA ports.

Honestly though if you only have a SATA 1 port you wont really see any performance boost. Your might be more satisfied with a 10,000RPM Hard drive, those units usually have transfer rates between 100-145MBs and your SATA I port is capable of a max transfer rate of 150MBs

I wouldn't stick a 10k RPM drive in a laptop. The cooling in general isn't very good and they make a lot of heat. Can you find an old SATA II drive? Those should work fine. Otherwise I'd buy from someone who has a great return policy. (or maybe have a local shop test it for you?)

@4745454b: true, I didnt consider the fact that it was in a laptop, yeah the heat and extra vibration of beign moved around probably wouldn't be ideal. If you could find a SSD with SATA II like 4745454b suggested, that would serve you best.

Thanks for the inputs everyone! I had decided to go for a 60 GB SATA III SSD from Transcend which is available for 50 bucks on Amazon.
The laptop is literally back from the dead after adding 2 GB RAM and 60 GB SSD. Boot time with Win7 is under 30 seconds which was earlier above 75 seconds with WinXP.
Total upgrade cost in india comes around 80 dollars.

Here are the components finally installed:
