How an SSD works?

Recently, you hear about the innovative use of SSD. In this article, we will try to familiarize you with the topic of SSD itself as well as we will look in more detail at one of the mass storage devices used in laptops and PCs, namely to the hard drive. Manufacturers such as: Samsung, or WD are outdoing each other in the production of SSD drives. More and more often this technology can be found, but it is still expensive and the memory size is not as large as in the case of ordinary disks so far not superseded by newer solutions.

First, let's try to explain the very concept of SSD. A storage device built on the basis of flash memory - this is the simplest definition of SSD itself. In English, the abbreviation SSD expands as a solid-state drive or also a solid-state disk. The very "solid-state" refers to solid state physics. Means the use of transistors in the device, unlike technologies that use vacuum tubes. When referring to SSD, this term additionally emphasizes the use of only stationary elements in the device, as opposed to hard drives containing movable mechanisms..

So let's check how SSD works. The principle of operation is similar to this, which is used in flash memory. As we mentioned before, the main advantage of SSD is the lack of moving parts. SSD disks are characterized by significantly shorter data access time. Also, quieter operation and much greater resistance to mechanical damage are the advantages of SSD technology. It is different from the point of view of industrial computers, where memory size does not count, and most of all, reliable operation and shock resistance. Branded SSD media are characterized by advanced technologies, which improve work and increase the lifespan of the entire memory, thanks to highly advanced data scattering algorithms on the disk surface.

A very important feature is the wide range of operating temperatures, which magnetic disks couldn't stand. SSD devices can operate constantly at temperatures ranging from -40 degrees Celsius up to 85 degrees. However, this is true for NAND Flash SLC drives. Industrial applications are often located in halls or in boxes outside the building, therefore, this feature is so important in the case of SSD drives. The main goal of SSD in such solutions is reliable operation. Therefore, resistance to low and high temperatures is a very advantageous feature for these devices. It is in industrial applications that SSDs are increasingly replacing ordinary HDDs.

The implementation of SSD memory for mass production will certainly result in a change in flash memory prices. It is directly related to the development of the Multi Level Cell technology, which is the basis for the development of SSD technology. These are some of the many properties, which has SSD memory. There are also some minor downside to the positives of this technology, but that's for you.
