We've said this many times before, but the big problem with old hard drive technology is that it doesn't always store your data in one continuous block, making it easier for your drive head to locate and load the relevant files. This is made worse when you have a large hard drive with lots of small files that you constantly write and delete from your drive. Over time, your drive will become fragmented with the data located in different areas, causing your system to spend more time loading data.03 Dec 2008
