FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A typical 7200 RPM HDD will deliver a read/write speed of 80-160MB/s. On the other hand, a standard SATA SSD will provide a read/write speed of between 200 MB/s to 550 MB/s.

Detailed explanation-2: -Although nowadays, you can find hard drives spinning up to 15000 RPM, the most popular ones for desktops and laptops are between 5400 and 7200 RPM.

Detailed explanation-3: -Spindle speed, measured in rotations per minute (RPM), is one metric used to gauge disk drive performance. Spindle speed can affect seek time, which is the speed at which a drive can locate a single bit of information, as well as the sustained rate at which data can be read from, or written to, a disk.

Detailed explanation-4: -A hard drive with a 5, 400 RPM will have a speed of around 100MBps. On the other hand, an HDD with 7, 200 RPM will have speeds of around 150MBps. An SSD, on the other hand, has no RPM to consider since it doesn’t have moving parts. With a SATA III connection, an SSD can read data at 550MPbs and write at 520MBps.

Detailed explanation-5: -In 1992, Seagate introduced the first ever 7200-RPM spindle speed hard drive, the Barracuda 1, sold in capacity of 1.7 GB with a size of 3.5 inches. On July 24, 1995, Seagate has shipped over one million Barracuda hard drives.
