These devices are attached to your computer using dedicated SATA cables, replaced by SAS cables for big servers and workstations. HDDs are the cheaper option but suffer from slower transfer speeds, while SDDs are their superior counterparts but are more expensive.

PCs use 2 common types of internal storage devices: hard disk drives (HDDs) and solid-state drives (SDDs). Unlike RAM, a storage device’s content is secured in non-volatile memory, meaning that data is saved permanently inside its memory bank, preserving them even after you turn off the PC (unless manually deleted or uninstalled). Storage deviceĪ storage device provides the memory for installing programs and saving files. Nevertheless, depending on your computing activities, you might not use all RAM, so you need to understand how much RAM is ideal for your PC according to its primary use (work, gaming, etc.).Īlthough a damaged RAM stick might not necessarily disrupt your computer from working properly, it will hinder its performance over time, resulting in program crashes, unexpected decrease in RAM, and failure to boot, among others. This allows the device to quickly absorb new data immediately during the next session, prompting quicker loading processes.Īlmost all mainstream computers can be upgraded with more RAM by buying a better RAM device - or RAM stick - that offers bigger storage capacity, including mini laptops. RAM is a volatile type of memory, meaning all stored memory is refreshed after turning off the PC. A RAM device keeps important currently-used data and codes on standby, loading them instantly when respective programs or apps are opened. Computers have different forms of memory that store information and data, and the more prominently discussed is random-access memory (RAM).
