I'm thinking of buying a higher capacity hard disk, a 320 or 500 GB one. I've heard that these HDDs slow down your computer. At present I've 1 GB RAM on a P-4 3.0 Ghz, and I am thinking of adding another 1 GB - would it solve the problem of the computer slowing down?All those who do have such HDDs, what is your experience with them? And how exactly have you fitted them? There are the portable ones, but they are too costly, and there are the internal ones, but I just came to know of another method, a USB method, where the USB pin or whatever it is called costs like rs. 400, and then you can plug in your normal (internal type) HDD SATA by USB, and remove it and carry it around whenever you want. A portable 500 GB one would cost around 8000 rs., while I've enquired of the price of an internal one here (in Ahmedabad), and it is somewhere around 3,400 rs (all the others whom I asked were quoting 5000 rs. prices) - now if I add that USB pin to this internal one, within 4000 rs. I would be able to get a portable HDD. This is what my computer guy has told me - he himself has connected a 320 GB SATA in this manner. If there are people on the forum who have done the same - does downloading from the internet to the USB HDD have the same speed?I'd really appreciate some help here.Thanks.
