Why is RAM more expensive than SSD?

Hard disks use spinning metal platters with a reading head moving along the surface, while RAM uses solid state technology. The design cost, as well as manufacturing cost, is significantly higher than that for a hard disk. Hence, the high cost.

What is ROM used for?

Short for read-only memory, ROM is a storage medium that is used with computers and other electronic devices. As the name indicates, data stored in ROM may only be read. It is either modified with extreme difficulty or not at all. ROM is mostly used for firmware updates.

Is SSD RAM or ROM?

SSDs use a special type of memory circuitry called non-volatile RAM (NVRAM) to store data, so everything stays in place even when the computer is turned off. Even though SSDs use memory chips instead of a mechanical platter that has to be read sequentially, they’re still slower than the computer’s RAM.

Why is RAM needed?

The more RAM your CPU has access to, the easier its job becomes, which enables a faster computer. If you do not have a sufficient amount of RAM than your CPU has to work much, much harder to transfer data, which severally damages the computer’s performance. Random access memory also helps your system support software.
