Name three types of hard drives, including their respective speeds and sizes.

There are several types of hard drives, each with different speeds and sizes. Here are three common types:

1.Hard Disk Drive (HDD):

• Speed: HDDs generally have rotational speeds measured in RPM (Revolutions Per Minute). They commonly range from 5,400 RPM to 7,200 RPM for consumer-grade drives, with higher-end models reaching 10,000 RPM or more.
• Size: HDDs are available in various sizes, commonly ranging from 500GB to multiple terabytes (TB) in storage capacity for consumer-grade models. Enterprise-grade HDDs can offer even larger capacities, reaching tens of terabytes.

2.Solid State Drive (SSD):

• Speed: SSDs are known for their significantly faster read and write speeds compared to HDDs. They utilize NAND flash memory and have no moving parts, resulting in faster data access and transfer speeds.
• Size: SSDs come in various sizes, often ranging from 120GB to 4TB for consumer-grade models. Some enterprise-grade SSDs offer larger capacities, reaching even higher terabytes.

3.Solid State Hybrid Drive (SSHD):

• Speed: SSHDs combine the features of both HDDs and SSDs. They have a traditional spinning HDD with a smaller integrated SSD cache. This cache allows frequently accessed data to be stored on the faster SSD portion, providing a balance between speed and storage capacity.
• Size: SSHDs typically have storage capacities similar to regular HDDs, ranging from around 500GB to multiple terabytes, with the added benefit of faster access to frequently used data stored in the SSD cache.

These sizes and speeds can vary depending on the specific models and advancements in technology. As technology evolves, newer models of hard drives with different capacities and improved speeds may become available in the market.
