When it comes to buying memory, various things come to play. First is the type of memory you want to buy and this is influenced by a number of factors. The first one is, what type of memory does your computer support? This is very important as some types care incompatible. The computer manual usually has explanations on whether you can combine the current memory with another type and if so, it gives the options that work well together. A memory upgrade also depends on how much memory you want to add. This will determine how much you spent. But there is a limit to how much you can add. Every computer has a maximum level beyond which you should not exceed. Most computers can accommodate up to 3GB. This should also be determined by the OS you use. Some use more RAM than others.

You can also consider additional space as found in custom USB. This form of storage is flexible, designed to meet your storage needs and can be bigger than the 4GB maximum in RAM. It is a good investment because in case of sudden shut downs, your files will be safely stored in the USB memory.
