    ST9120821AS is the 120GB drive that I believe has an 8MB cache and SATA150 and is listed as coming in my wife's HP Pavilion dv9548us Notebook PC.

    With all the choices how large might I go with speed not a real issue? 7200 rpm, 500g and larger cache sounds good it is just I just do not know. Help me do the right thing bang for my buck.

    Any help would be kindly received.

    Thanks

    Anything but the latest 1TB drives (12.5mm thick) should work just fine. If I remember right, there's only room for 9.5mm standard thick drives.

    Price/size/performance-wise the sweet spot is around 500GB today.

    So the 1T drives are too thick? I wasn't even thinking that large. What make up 2.5" form factor? If I get you correctly I could pick just about any 500g 2.5" form factor drive. Would my HP Pavilion dv9548us Laptop make use of performance the drives that are more modern? I don't understand the dimensions you mention.

    Standard laptop drive is 2.5" wide, about 3.5" long and 9.5mm thick (no idea how much that would be in inches :p ) Most laptops aren't designed to take thicker drives. That I found out the hard way, as I was installing 1TB 12.5mm drive in a laptop and suprise, it didn't fit... :D

    I then did look further on this subject and all current drives I quickly checked up to 750GB size were 9.5mm thick, so it's quite safe to assume everything up to 750GB fits your computer for sure.

    1TB size is currently the exception, technology isn't yet there to make that size in thinner frame. That will change, it always will :)
