The main step is to open it and see if they've used a custom connection interface.

The most important specification is the thickness or height of hard drive compared to space in drive bay

old large capacity 2.5" drives may be too thick to fit

standard laptops usually accept 9.5 mm (3/8") drives
but you need to look at specification for your model Sony Vaio and if the user guide gives details of drive size / interface and how to remove hard drive

bigger cache is better but costs more
7200 rpm drives usually faster but run hotter and use more power
