Traditional hard disk drives or HDDs, have moving parts that take time to get from point A to point B. Think of them aa Cassette tape, it takes time to get from the part of the song you were listening to, to the part you want to be at. While a HDD is many times faster than a cassette drive they are both loosely based on the same magnetic recording technology. Unlike a Cassette, a hard disk platter can spin up to 170 MPH to find the appropriate information you are looking for. This can vary based on the number of rotations per minute or RPM that the platter can do (between 3,000 all the way up to 15,000 for high performance servers). To improve performance even further people began defragmenting their hard disk drives in order to put the most important information on the “outside of the HDD” where the platter could find it the quickest. Despite what may seem like a fast way to do things, consumers have experienced the drag that even the fastest hard disk drive could not rectify. This is where Solid State Drives come in.
Solid State Drives
You’ve probably seen the flash drives everyone carries around. Solid State Drive is basically just a big versions of these that are used to boot and run your most important information. With USB 3.0 these drives can find information instantaneously and bring it to the user. This is because unlike traditional HDDs, solid state drives function without moving parts. No moving parts means: your computer and laptop are more energy efficient and have faster loading times, no risk of loosing data due to shock or suddent impact, and lastly SSDs produce absolutely no noise. The fact that SSDs are very energy efficient would be especially important for the laptop owners as it will increase the battery life. Most solid state drives come with a three year warranty as well. Manufacturers can offer this because SSD are much more durable than traditional HDD (they average around 2 million hours of run time before failure).
What’s the Fastest Solid State Drive of 2011?
Intel’s 510 series can read up to 500MB/s while using a Sata III connection, the fastest by far. This is because these SSD use Intel’s leading 34nm NAND flash memory technology. That is if we’re talking about affordable storage. On the other side of the spectrum you can get 1 and even 2 GB of SSD real estate linked in RAID0 on a PCI card (official OCZ site). OCZ is known for being a pioneer in delivering the fastest read and write speeds.

While it sounds great in theory to have a drive that can load everything much quicker than a HDD it does have its limitations. Most SDD are limited in their capacity and for their size are much more expensive than HDD. For example you can get a 2 TB HDD for under $100 whereas a 256 GB SDD will cost you $500 and up.
Why Do Solid State Drives Cost So Much?
Supply and Demand. SDD cost a lot because they use a NAND flash chip. In 2010, 11 exabytes of NAND memory was manufactured. Most of that went to other devices like tablets, MP3 Players, memory cards, and mobile phones. SSD comprises just 7% of that. Despite a growth of around 81% in the amount of these chips manufactured, there simply is just not enough to go around, yet.
What’s the Top 120 GB Solid State Drive?
OCZ has consistently had great feedback and ratings from consumers. Because of their low prices, they are hard to beat in the SSD market. Although the OCZ 120GB Vertex 2 series was voted “best of the best” by maximum PC magazine, the best selling 120GB SDD is still the Intel X25M. On the other hand, the OCZ vertex 2 at 120GB is $20 cheaper. While it’s more economical to go with the OCZ Vertex 2, the Intel X25M comes with a 3 year warranty.
