Currently, efforts in the SSD industry are focusing on making higher-capacity SSDs. For example, Other World Computing is working on developing a 2 TB SSD to be used in Mac Pros. These drives generally have a maximum capacity of 512 MB are larger in size than those used in laptops.
Modern devices that employ SSDs include computers, video game consoles, memory sticks, cell phones, MP3 players and memory cards for digital cameras.
Furthermore, HDDs rely on a small arm that writes information onto the spinning disc which stores information. So, not only is the spinning disc used to contain the information delicate in HDDs, the arm used to write the information is also prone to malfunctions.
The first SSD was developed by Dataram in 1976. It was called the Bulk Core and had 2 MB of storage capacity. The Bulk Core retailed for $9700 when it was first released.
Along with speed, another advantage of SSDs in comparison to HDDs is durability. Because HDDs utilize spinning magnetic discs, they are susceptible to damage. SSDs, on the other hand, have no moving components and are therefor more durable.
HDD devices such as early iPods were susceptible to damage from impacts such as being dropped, vibrations and the movements associated with running and exercising. New iTouches, though, are Flash based so they are able to be used with minimal fear of damage during exercise and other physical activities.
Though SSDs are more expensive and have less overall storage capacity compared to HDDs, they are superior to HDDs when it comes to speed. Computers and other devices equipped with SSDs can boot-up in seconds and transfer files and other information much faster than devices equipped with HDDs.
Another disadvantage of SSDs when compared to HDDs is the overall storage capacity. While SSDs generally max out at 1TB of storage space, HDDs can have over 4TB of capacity.
The main downfall of SSDs is price. While hard disc drives (HDDs) which have been around for years cost approximately 10-30 cents per gigabyte of storage capacity depending on the dimensions of the hard drive, SSDs can cost up to $3 per gigabyte of capacity.
SSDs work via semiconductors which rely solely on electronic connections to store and transfer information. Semiconductors were first used in radios and similar electronic devices.
Solid state drives are devices used for storing information in electronic devices such as computers and MP3 players. They replace the older style hard drives which used spinning, magnetic discs to store information.
