how does hard disk affect the performance of a computer

Using a faster disk, such as an SSD, will typically give you better read and write performance compared to an older HDD, but how does this affect PC gaming? On a computer with a fast CPU but a slow hard drive, reading a compressed file might actually be faster. The hard disk performance directly affects everything else on the computer and is therefore the weakest link. The faster the platters of hard disk spin, the less time the hard drive will take to pull upon a certain data. Such a feature greatly improves disk performance. Some SATA II and later hard disk drives support staggered spin-up, allowing the computer to spin up the drives in sequence to reduce load on the power supply when booting. There's a chance your page file is largely fragmented (depending on when you last defragmented, which is best done monthly), and also that your game data is all over the disk. TLDR: It depends If we are talking the difference in frame rates of a 5K rpm drive vs 7.2K rpm drive then no. I use an utility called "WinContig". Two major factors that impacts computer performance related to the hard disk drive are how the file is/files are scattered across the hard drive (known as fragmenting) and the location on the drive. The only disk based factor (along with actual drive performance) that would affect performance is how much fragmented your drive is. This can affect your computer's overall speed, since the computer's pretty much just waiting on data while those platters spin, regardless of the speed of the computer… When you load a compressed file, the CPU has to do more work decompressing it. Well, that depends. However, reformatting a hard drive deletes all files on a computer, including the harmful ones, and returns the system to peak performance. To keep your PC’s hard drive working at maximum efficiency, it should be regularly defragmented. Disk -- Because of the limited page fault activity, disk I/O bandwidth would be minimally impacted Now in other aspects it can. Freeing up disk space does not speed up computers, but reduces file fragmentation chances. However, that compressed file is smaller on the disk, so your computer can load the compressed data from disk faster. Spyware and viruses can be very harmful to a computer's overall performance, and although virus scanners and other utility programs can help to remove these malicious items, they are not always successful. In fact frame rates are hardly effect your frame rates. The moral of this story is that fragmentation is a good and necessary thing.
