Hi Yanger_zuu,
Welcome to Sony Community!
We don't recommend any upgrade on Vaio laptops because they're integrated with each other. Replacing any parts might do more damage to the laptop. To prevent unforeseen issues, I professionally suggest you stay with the currently installed hard disc drive.
For further assistance regarding your concern, please contact the Sony offices/Sony representative offices nearest to your place of residence in Asia Pacific region http://www.sony-asia.com/countryselector.html?hpid=countryselector:AsiaPacific. Due to proximity, they are in a better position to respond to your questions or concerns.
Regards,
Jen
