SSD (Solid State Drive)

What they are/ how they work

Solid state drives are storage device that stores data on NAND-based flash memory. They are nonvolatile, which means they work without power, and data can be stored up to 200 years, outliving people. It can thought as a far more advanced and sophistacated USB drive for comparison. Solid state drives aren't traditional hard drives because there are no moving parts. A HDD consists of a spinning disk, which the SSD does not contain. A SSD is an array of semiconductor microchips used for memory organized as a disk drive using integrated circuits, not using magnetic storage, which makes it not susceptible to magnetism. The SSD has an embedded processor or “brain” called a controller to perform operations such as reading and writing data. The Controller is a crucial component of what makes the SSD so fast. The decisions it makes regarding how to store, casche, cleam etc. determine the overall speed of the SSD, the better the controller in the SSD, the faster the SSD will be. Operation the SSD performs are:


SSD began in the early 1950’s when Dataram produced a large, slow, and expensive solid state drive. It was popular because of its high price for low quality. In the 1970’s it began to slowly get smaller and faster, but the price did not go down and it only had a ten year life span.Th push for faster and cheaper SSD’s grew and more companies donated resources to it. More models began being released, each evolving from the last. The first primary SSd came in the early 2000s with the rise of netbooks. The SSd chip could have a permanent fixed position and could replace the hard drive, saving space and time. A Current SSD on the market the miniPCI SSD card has the capacity of 1TB. SSD have changed widely since their beginning, opposed to HDD’s. This offers a more promising future than HDD’s.

Why is SSD better?

A HDD consists of a spinning disk, which the SSD does not contain. The HDD uses a mechanical arm with a read or write head and read information from the right location on the stprage platter. An analogy for this is put perfectly by the website “storage

"Having to walk across the room to retrieve a book to get information or simply magically having that book open in front of you when you need it? That’s how an HDD compares to an SSD; it simply requires more physical labor (mechanical movement) to get information."

What makes the SSD more desirable is because, it is faster, quieter, uses less power, admites less heat, and no vibration. HDD’s are cheaper and can store more data, but with the downside its workings. A HDD is aproxomitley $0.03 per gigabyte, a SSD is aproximtely $0.20. HDD are more widely ued because of the larger stoarge capabilities and cost, but the SSD mechanically is far superior.
