no I'm pretty sure that it's the drive that saves all your work and that has all of your file
Any laptop with a Core i7 processor will be very fast. In addition, solid state hard drives will make for a very fast computer.
well, you can keep the amount of data on it to a minimum, which would make it faster
Not really, no. However if your boot hard disk was near max capacity and you freed up some space on it by moving stuff to the portable hard drive, THAT might make your computer run quite a bit faster.
It depends what you are talking about. External hard drives should have no problem running on a Vaio laptop but if you are going to try to replace the main HD, good luck. Make sure the size fits.
To make them easy to upgrade.
Hard drive speeds of 7200rpm allow for it to read/write/copy data faster, but this doesn't necessarily mean it will open programs faster. If you want to run programs faster, upgrade your computer's RAM (random access memory or usually just called memory).
When shopping for hard drives you should make sure that it is compatible with your computer. You should also make sure it's big enough for your files.
No, overall, hard drives just give you more storage space. Newer hard drives tend to be faster than older ones, but that only affects disk-intensive activity, not processor or RAM-intensive things. If you want your computer to go faster, your better off buying a better processor. More and/or faster RAM can help too.
Get a faster internet connection lol
There are many different brands of external hard drives. Although most people do not think they ever need an external hard drive, it is always good to have one just in case. The most reliable brands of external hard drives are Western Digital and Seagate.
Several companies make hard drives. Seagate is the biggest name now, but Fujitsu, Toshiba and some smaller ones make drives also.
I think you have to uninstall programs that you have downloaded
