A 10,000 RPM hard drive is the fastest drive available. They're more expensive but they provide great support for your disk I/O operations. Notice here that if we have a 10,000 RPM drive, we are spinning the disks inside the hard disk drive at about twice the speed of the 5400 RPM drive. That means that the disk can read and write dataalmost twice as fast as a low end 5400 RPM drive. Now it doesn't seem like this would make that big of a difference but it really does. If your system is using currently a 5400 RPM drive, you can dramatically increase the performance of your storage system by upgrading to the fastest hard disk rotational speed possible. Upgrade the Disk Interface 2:32-3:07 The second thing you can do to optimize the performance of your storage system is to use the fastest interface. You should consider upgrading your disk interface and your hard disks. The reason for this is that the slowest SATA standard transfers data at 150 megabytes per second. SATA 2.0 can transfer data at 300 megabytes per second. And SATA 3.0 can transfer data at 600 megabytes per second. So from a hardware perspective, you should upgrade your hard disk to disks with the fastest rotational speed that you can afford, and you should also consider upgrading your disk interface. You should be using the fastest version of SATA available. Software 3:08-3:12 Now let's take a look at how we can optimize our storage devices using software. Use Disk Cleanup 3:13-5:44 The first thing we need to do is to keep the hard disk clean. When I say keep your disk clean, I'm not talking about dusting it off every now and then, although it's not a bad idea. I'm talk about getting rid of the stuff on your hard drive that you don't need because a drive that is mostly full is slower.

The hard disk interface must search all over the hard disk drive to find pieces of that file that you're trying to open. Or if you were trying to save a file, the hard disk interface must search for an empty space to save it. Now this isn't a huge performance issue but it is there and it can be noticeable,especially if the hard disk is getting full. Therefore, you should try to keep your devices as clean as possible. There are a lot of things on your hard disk that you can get rid of. Every time you open up a web browser and visit a website on the Internet, the webpage that your browser downloads is cached on your hard disk drive. Both the webpage itself, along with the all graphics that are referenced in that page are cached in your hard disk drive and over time, it adds up. One webpage is not that big of a deal, but you're probably looking at anywhere from about 20 to maybe 100 kilobytes of data consumed on your hard disk drive for a single webpage. If you start having hundreds or even thousands of webpages cached on your hard disk drive, then it can take up a lot of disk space.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
