Computers and other electronic devices involve multiple functions. In their operation, it is inevitable to store data like document files, photos, music, applications, videos, and other more. In computers and similar electronic devices, varied components are utilized stacking data. Basically, there is the Ram or Random Access Memory, the HDD or Hard Disk Drive, and the SSD or Solid State Drive. Older versions of the foregoing devices make use of the RAM or Random Access Memory.
A RAM is located in the motherboard. They appear to be a set of magnetic plates with a reading needle. The Random Access Memory is a component for storing data to the extent of about 8 gigabytes. Meanwhile, the HDD is used for as a massive storage component. It can hold data up to 500 gigabytes. HDD is present in all laptops and computers. An HDD can however be replaced with a more powerful storage device which is the SDD.
The SDD is commonly flash-based. A flash-memory based SSD hosting device is a non-volatile memory which allows retention of all sorts of data even without power. The flash-memory based SSD hosting device is not mechanical and has excellent semiconductor properties. This is why SSD hosting devices operates efficiently and without making any unnecessary noise while in operation. Aesthetically, an SSD hosting component looks akin to an HDD. They are rectangular in shape and couched in a metal shell following the standard form for hard drives. SSD hosting components are typically small and fit perfectly in computers, laptops, and tablets. Beneath the casing, you can find an array of cells or chips fixed on a board. This allows the SSD to be more stable and operate quietly.
An SSD hosting device operates with two classes of flash memory. This is the NOR and NAND. Both types of flash memory contain cells, pages, and blocks. There is a difference only with respect to how they are designed. The NOR flash contains parallel cells, unlike the NAND flash wherein the cells are arranged in a series. Of both memory types, the NOR flash memory appears to be more complicated since it is comprised of multiple wires. It is also bigger than NAND flash. On the other hand, a NAND flash’ series of cells allows a more rapid process of reading, writing, and storing of data. Of the two types, the NAND flash memory is more convenient and the predominant class. NOR flash can also be used though for slow paced read-only applications.
