What is SSD (Solid State Drive) and How It Works

Solid State Drives are usually the lighting new fast kid on the hard drive block; however are they a good match for you?  Please, read on as I discuss about it.

We have seen a mark raise in the amount of SSDs in the last few years and less expensive (although it specifically could not sense that way when you compare prices between solid state disk (SSDs) and traditional HDDs). What is an SSD? How do we benefit the most from paying the premium to get an SSD? What do you really want to do differently if any with an SSD? Please, continue to read.

What Is a Solid State Drive?

Although this could be hard to believe however Solid State Drives are fairly old technology. Solid State Drives for many decades now have been around in various forms, the earliest of this were RAM-based and which were very expensive that it only make appearances in super  computers and ultra-high-end. In the 1990ѕ. Flash-based SSDs made an appearance however were again still far costly for the consumer market and create hardly a blip that are outside of specialized computing circles.

An SSD uses a kind of memory known as “flash memory” that is the same with RAM. But, unlike RAM, that clears whenever the computer is put off, Solid State Drive memory remains even as it loses power.

If perhaps you were supposed to take break a form of hard disk, you would see a magnetic stack plates on an axis with a needle–kind of like a vinyl record player. This needle could write or read to the plate only before it pin around to the rights pot. Solid State Drives, you can also use a grid of electrical cells to quickly receive and send data. Grids are usually separated into section known as “pages,” and the pages are where the data is been stored. Pages are usually clumped together to from what is called “blocks.”

Advantages of Solid State Drives

  • Fast boot time.
  • Fast data access. Up to 550 MB read and write per second. Ten time faster than HDD.
  • Working silent.
  • Less power usage and heat.
  • Less space than HDD.
  • Less mistakes writing and reading data.

How Does Solid State Drives Work

The reason this is important to know is due to the fact that SSDs can just write to empty pages in a block. In a hard disk, data could be written to location anywhere and anytime on the plate, which means data could be overwritten with ease. Solid State Drives could not overwrite data directly. Rather, SSD ought to first of all find an empty page in a block which will then write to that empty page.

Therefore how does a Solid State Drives handle data deletion? Whenever sufficient pages in a block are marked as unread, this solid state drive will take the whole content of that particular block, subject it to a memory, and erase the whole block.

Does it mean the SSD become slower with time?

Whenever you a new SSD, it’s full totally with blocks loaded with blank pages. Whenever you lоаd a fresh data to it, the SSD, it could instantly write it into those empty pages with blazing speeds.  But as you put it to use, you will at the end run out of empty pages and which will make you to be left with scattered and random pages that are useless.
