Ever heard of a hardisk without a spinning motor inside? Yes, there is already a hardisk without a physical motor spinning inside…

They called it SSD..meaning “SOLID STATE DEVICE”. Although this technology was already implemented since 1970’s, it was not so popular due to high price. In analogy to USB flash, you can say SSD is a bigger USB flash drive as the technology is almost similar to it.

Some of the advantages of SSD:

• faster reading of files as there is no spinning motor
• low power consumption
• no vibration and sound
• longer failure time as no moving mechanical parts inside
• high resistance to shock as there is no moving parts making it useful for mobile use such as laptops

Although a lot of advantages, it also has disadvantages:

• lower capacity compared to normal hardisk. currently 80 gb as commercial product from Intel
• limited write erase cycles just like the USB flash drive. based on the Intel X25-M data sheet, it has a write endurance of 1 petabyte of lifetime random writes equalling to around 1000 terabytes.. huh ..
• Mean Time Before Failure(MTBF) is also measured as 2,000,000 hours.

As of to date, only Intel has the best SSD product in the market today..
