What is Solid State Technology?

What is Solid State Technology? I am sure you all very curious about solid state drive technology and its implications on USB flash drives. In this post, you will find information about solid state technology and usage of this powerful technology on future USB drives.

What is Solid State Technology?

A new storage technology Solid State has emerged in the data environment. This new storage technology has changed some storage parameters like size, capacity or performance fundamentally. In fact, the SSD technology was not new but it was too expensive to use in common device like USB drives.

After the Apple products, which uses some form of solid state technology, the solid-state technology has begun to spread. Then the manufacturers have begun to develop solid-state technology for creating Solid State Drives or shortly SSD. When you look at the storage devices the appearance was same, I mean the shape or usage of Hard Disk Drives (HDD) or USB Drives were same. But inside technology and the performance was totally different.

Basically, the HDDs uses a mechanical part to read the data on the disk. When it starts to work you can hear the spinning and the reading sound. In contrast, SSD is a stable memory, there is no any moving part inside. That specialty gives ”Solid State” to the technology. This stable feature gives a very important advantage to the SSDs. They are less fragile than any other HHDs. That’s why today the solid state technology is very widespread in the smartphone or digital camera environment.

As like HDDs, the Solid State Drives have three main parts. These are storage part, a controller for manage, and a host interface.

How a Solid State Drive Works?

After learning what is Solid State Technology now let’s look at the basic work principle of an SSD. On most SSDs an electron-based trapped charge storage media called NAND is being used. NAND is a type of nonvolatile memory that retains data when power is lost. Basically, the NAND cell stores electrons on a capacitor indefinitely in a no-power state. The charge is then sensed by circuitry on the NAND chip.

Writing to NAND flash is accomplished by either adding electrons to (programming) or removing electrons from (erasing) the memory cell using high-voltage pulses.

Features of SSDs

There are basic differences between HDDs or classic USB drives and SSD drives. Below you can find these basic advantages and disadvantages.


  • No moving part inside,
  • No sound while working,
  • More durable than HDDs and have resistance to physical shocks,
  • More speedy operating system.


  • More expensive than other counterparts.

Solid State USB Drives

Nowadays the solid state technology has begun to be incorporated USB flash drives. Some giant USB drive companies now trying to use full benefit of solid-state technology in their products.

For example, Sandisk recently revealed its new Solid State USB drive, SanDisk Extreme PRO USB 3.1 Solid State Flash DriveIt was released to the market as the fastest USB flash drive with its super fast solid state technology. With its 420MB/s read speeds and up to 380MB/s write speeds the SanDisk Extreme PRO USB 3.1 Solid State Flash Drive is really impressed the USB drive world. In order to understand that amazing speed, I can say you can transfer a 4K movie to drive in less than 15 seconds. You can reach the more features of this fastest USB flash drive by clicking on the link.

Another example can be VisionTek USB 3.0 Pocket Solid State Drive. This solid-state USB drive also has solid state technology with SuperSpeed USB 3.0 performance and it is almost 10 times faster than USB 2.0.  

Although there are lots of external SSD hard drives, you cannot find enough Solid State USB Flash Drive products in the market. After Sandisk’s introduction of SanDisk Extreme PRO USB 3.1 Solid State Flash Drive I am sure other USB drive companies will speed up for their own Solid State USB Drives. Maybe in the near future, we will see a different mark and model solid-state USB drive products.
