There is almost a hard written rule that replacing computers, laptops smartphones and other mobile devices need to be done within x number of years and that number is usually less than 5 years. Either office workers are used to snappy results and fast load times or that slowing speeds is a sign of being less productive and impatient finger tapping ensues. It is also a much more profitable solution to replace entire systems than small upgrades. The questions that needs to be asked is, is it going to enhance productivity, improve efficiency and improve workflow. The other major concern can be newer apps and software not working on older hardware which can especially be true for Operating Systems that just won’t run well on older systems. Apple is good at simply not allowing newer OS releases from even downloading and installing on older systems. This again can lead to users feeling left behind in a fast paced cyber world of connected devices, fast internet speeds and busy schedules.
Most notably the first part of a laptop that slows down is the hard drive since more and more data is being stored on the drive. Since data recording starts on the outside of the drive, the farther the data moves inwards to the inner part of the drive the slower the drive becomes. This is because physically, the hard drive is actually spinning at a faster rate (which is the drives maximum speed) than towards the center of that drive. Also, there is no need for as much efficient data placement on the physical drive since 1’s and 0’s can be placed almost anywhere within the outer part of a drive. Solid State Drives are much faster and store data a little differently so it is much less noticeable.
