What is SSD?
These three letters appeared in the computer world for quite some time. But they began to gain popularity only now. Namely, in the moments of the release of new laptops with SSD-drives and players with it. So what was the benefit of using SSDs? This is what I will try to tell you.
Initially Solid State Disk – SSD was designed to replace a regular hard disk. But in the years of its creation, few people made a bet on the future and really thought about installing them into their devices. At that time, the price was high, and the development did not attract much attention.
A dozen years later, finally began to produce devices in which instead of the usual hard drives used SSD. And when the year 2008 came, the manufacturers again recalled the existence of the Solid State Disk. Now these hard drives are used in many new technological developments.
Why did you still remember about SSD hard drives? First, the price dropped. Now one gigabyte is worth such a hard drive worth about 14-18 dollars. It turns out the 64 GB drive is currently worth about $ 700. All the same, it is expensive, but prices are not as exorbitant as they were before. They reached several thousand.
Secondly, in the development of compact devices, these hard drives fit just right. They are small and their weight is quite small. But the biggest plus is their protection against data loss. If during the fall of the usual hard drive you could almost say one hundred percent that you would lose information, then the SSD hard drive will not allow this.
In the production of SSD has its own characteristics. There are two technologies that are used for the production of NAND-flash memory – SLC and MLC.
SLC – single-level-cell is a chip-based technology with single-bit data recording technology. This means that for a single cell is used to store one bit of data.
MLC – single-level-cell is a multi-level charge technology. This means that for one cell it is capable of storing not one, but as many as 4 bits of data.
Thanks to these technologies, the user wins in the speed of recording and rewriting information. At this stage, the only minus is reading the data. But in the future, developers hope to fix this flaw.
The undoubted disadvantage of the SSD is that their service life is limited. It depends on the number of entries and overwrites. So far it has been said that such a hard disk can withstand about 2 million rewrites. Although the figure is large, but if you work with documents, then I think it may seem rather small. I hope the developers will also deal with this problem.
