One of the most confusing sets of terms in everyday computer usage is “‘Memory’ & ‘Storage’.” People often use one term when they mean to refer to the other thing. It can be confusing because both memory and storage are measured in the same units: bytes, kilobytes, megabytes, etc. This is because both memory and storage are places to hold your data, but they do very different things with it. The two components that ‘memory’ & ‘storage’ refer to are RAM & the hard drive. The memory is known as RAM. It is is a part of your computer that it uses while it’s powered on. Your computer stores everything that it’s thinking about in RAM. If you’re running a program, it’s in RAM. If you’re looking at a webpage, it’s in RAM. RAM contains everything that’s currently going on with your computer. And when RAM is in a computer that isn’t powered, the RAM is empty. It’s just waiting for something to think about. The more memory your computer has, the more it’s able to think about at the same time. More RAM allows you to use more complex programs and more of them. Storage’ refers to long-term storage. Everything that your computer knows, but isn’t thinking about, is in storage, written on the Hard Disk Drive (HDD). This is a permanent type of storage: hard drives can be unplugged and contain the same information as when they’re plugged in or turned on. Nothing actually gets changed on the hard drive: it gets pulled off the hard drive, into RAM/Memory. While it’s in memory, you as the user can change it. When you save the information, it gets sent back to the hard drive storage in a different version. More hard drive storage allows you to store more things on your computer. However, it rarely affects your computer’s performance. A computer with 1 gigabyte of RAM will work at the same speed whether it has 2 gigabytes of storage or 2000 gigabytes.

Memory (RAM) and storage are both required to run a computer. They both store data,the difference is in how long the data is stored.
The main difference between computer memory and storage is that memory stores data short-term for immediate access. A computer's moment-to-moment operations are performed using short-term data access — loading applications, browsing the Web, or editing a spreadsheet. Memory is volatile storage, which means that when you turn the computer off, the data disappears. For more information on what RAM does, read here. Storage (either a hard drive or a solid state drive) stores data long-term for permanent access. It's the component that accesses and stores your files, applications, and operating system. The storage drive is non-volatile, which means the data is stored even if you turn off the computer. For more information about solid state drives, read here. Memory and storage work in tandem with your computer's processor (CPU) to access and use data.
The three components work together to display the program and file you want, and record your changes.
Because of how your system accesses data, the speed of your memory and storage drive plays a big role in how fast your processor is able to convert data to and from the different data types and make it usable. Because slower memory and storage components can cause data bottlenecks, it's best to upgrade one or both components. If your system seems slow, unresponsive, or sluggish compared to when you first bought it, we recommend upgrading your memory, storage, or both for optimal performance gains. |
