The difference between SSD and HDD

[mouakter13]

In 2003, Transcend introduced inexpensive flash SSDs with a Parallel Advanced Technology Attachment (ATA) connector that cost as little as $50. The PATA connector connected hard drives to computers.

It was not until 2006 that flash SSDs were mass marketed by Samsung with 32 GB capacity and a PATA interface. In 2009, OCZ Technology introduced a 1 TB flash-based SSD, while Virident Systems developed a second generation of flash-based SSDs with up to 2.2 TB of storage in 2012.

In late 2012, we saw reliable enterprise flash drives for high-performance applications, such as Intel's SDD DC S3700 . The increasing need for speed, high performance and reliability are critical factors for the growth and advancement of SSDs over HDDs.

To understand the hype around SSDs, you first need to understand how they work and how they differ from legacy storage technology like HDDs. Although SSDs and HDDs are both used to store data, they thailand whatsapp number data function differently.

How the hard drive works
HDDs have been around longer than SSDs. You can find them in various electronic devices such as desktop computers, laptops, gaming consoles, mobile phones, and tablets. However, it is now considered an old technology for storing data due to its method of operation.
