Information Communication Technology ICT – 3 Storage devices and media | e-Consult

Fixed SSDs, also known as internal SSDs, are designed to be installed inside a computer's motherboard. They typically come in standard sizes like 2.5-inch or M.2 form factors. Their primary use is as the main storage device for the operating system, applications, and data, leading to faster boot times and application loading compared to traditional hard disk drives (HDDs). Advantages include significantly faster read/write speeds, greater durability due to the absence of moving parts, and lower power consumption. Disadvantages are generally higher cost per gigabyte compared to HDDs and limited upgradability once installed.

Portable SSDs, often referred to as external SSDs, are self-contained units that connect to a computer via a USB port. They are typically smaller and more robust than fixed SSDs, making them ideal for data backup, file transfer, and on-the-go storage. Advantages include portability, ease of use, and fast data transfer speeds. Disadvantages include a potentially higher cost per gigabyte than internal SSDs and reliance on a USB connection.

Here's a table summarizing the key differences:
