The more random access memory (RAM) your computer has, the faster its performance is likely to be. Computers and other devices that utilize 80GB or 200GB of RAM generally are not available to the average consumer, at the time of publication. Technical specifications referencing those memory sizes are likely referring to a device's hard drive.
The amount of RAM on a device is typically much smaller than that of its permanent storage, or hard drive. Hard drives can be found featuring more than 1 terabyte of storage space (1TB equals 1,000GB) on computers sold at retail outlets. RAM, on the other hand, generally is available in sizes up to 32GB in high-end, performance-intensive gaming computers from Alienware, according to the company's website, as of the date of publication. Although RAM is most commonly referred to in conjunction with computers, it is used with many types of electronics, including smartphones and video game systems.
Computers typically afford you the ability to upgrade the amount of RAM in the system, above and beyond the initial amount included at retail, with the limitation being the operating system that the computer is running. If your system is running the X64, or 64-bit versions of Windows 7 Ultimate, Enterprise or Professional, for example, its RAM can be expanded to 192GB. Windows Server 2008 R2 allows you to expand your system's RAM up to 2TB on some versions, according to Microsoft. These large amounts of RAM are necessary only if you're running a large server for a business network or website, or if you're attempting to build a supercomputer. With most new PCs still shipping with less than 10GB of RAM as of the date of publication, it will likely be several years before retail systems have 80GB to 200GB of RAM.
Simply put, 200GB of RAM can hold a significant amount of additional information in comparison to 80GB. An additional 120GB of memory can provide the storage space for 23,100 more MP3 files or 210 more hours of video footage, according to CFgear.com. This additional space can improve your computer's performance by allowing it to run more programs simultaneously, as opposed to having to potentially access the files multiple times from the hard drive due to insufficient RAM. Install a larger amount of RAM if you intend to run multiple programs that heavily tax your system, including video games.
The amount of RAM doesn't tell the entire story of how it can affect your computer's performance. RAM comes in different types, including single data rate (SDRAM), double data rate (DDR), DDR2 and DDR3, which signify different generations of RAM technology. Check the type of RAM your device uses or that you intend to purchase to ensure it is using the newest technology possible. The DDR3 type of RAM is the newest generation, with SDRAM being the oldest commonly used type, as of the date of publication. DDR3 offers improved access speed, allowing your computer to access files stored in its RAM much quicker than prior generations. So while 200GB of RAM offers a significantly larger storage space, 80GB of RAM using newer technology may let you access information quicker.
