As the controller will make decision to where it will store, retrieve, cache and clean up data that can determine the overall SSD performance. The controller is a very important factor in determining the SSD read and write speed. An SSD does not have any mechanical components to read and write data, instead it relies on an embedded processor called a controller to perform operations related to reading and writing data. A non-volatile memory is that it will not forget where the data is store when the disk is off. A typical SSD uses what is called NAND-based flash memory, which is a non-volatile type of memory. Storing data on a chip is what makes the SSD so much faster. Like a USB memory drive, there are no moving parts, and the data is stored in microchips. SSD stands for Solid State Drive, and it’s like an oversized, more sophisticated version of a USB memory stick. SSD is also way faster – 10 times faster than an HDD.
SSD is also considerably smaller and takes up less space in a PC case, in some instances even mounted directly to the motherboard.
What’s the difference between SSD and Mechanical HDD? The simple answer is that SSD has no moving parts and functions similarly to USB memory sticks, while the Mechanical HDD has a magnetic tape and a lot of moving parts. What’s the difference between SSD and Mechanical HDD?
