FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Even here the typical maximum rotational rate used is around 5000 rpm.

Detailed explanation-2: -SATA hard drives are incredibly fast compared to their predecessor, the PATA hard drive, and can write to the disk with an interface rate of 6 Gb/s with a throughput of 600 MB/s. A single drive can range from 500 GB to 16 TB and are available at a lower cost than any of the other drive types discussed here.

Detailed explanation-3: -With no moving parts, they can read, write, and access data faster than HDDs. Many computers and tablets are now equipped with an SSD pre-installed instead of a traditional hard drive. Solid state drives typically access data faster, accelerate apps, and speed-up a computer’s boot-up time.

Detailed explanation-4: -Rotational latency (in milliseconds) describes the time required to position a specific sector under the read–write head. Average latency is typically given as the time it takes the drive to perform half a rotation of the platter, and is directly dependent on its RPM rating.
