What Is SSD

Everywhere I look for information on SSD drives I am bombarded with reviews and statistics. What I am really looking for is a brief explanation about SSD and how it might be better than conventional hard disk drives. What is SSD?

What is SSD

I want to know about the the primary differences between the two. Are their physical components different? Do they both do the job in the same way?

What is SSD?

Is it because SSD rely on memory chips that they have no moving parts? If there is nothing moving around inside the case, can SSD drives suffer from mechanical breakdown? If not, isn't this is good news for us? I ask you again, what is ssd?

I read an article on PCWORLD that said HDD manufacturers claim a .88% annual failure rate. But there was a study that found that 2%-4% was a more realistic number. One of the things that really got my attention was the fact that there was up to a 13% failure rate on some systems!

Once I read that it became clear why some people have begun to focus on SDD technology. It would only make sense that getting rid of the moving parts inside of the drive, you can alleviated a bunch of headaches!

So if there are no moving parts, what is in there? From what I can tell, there isn't too much. So what is SSD? They are made up of two main parts, memory chips and a controller.

I guess most of today’s SSD memory chips are NAND Flash non-volatile type. When they say non-volatile I guess they mean that they are unlike RAM chips. SSD memory does not forget what is stored when the drive loses power. Imagine that, a hard drive that that actually store files regardless of losing power. Maybe I answered my own question of what is ssd.
