What is a Solid State Disk (SSD)?
Solid state disks are NAND flash-based memory drives. This concept isn’t entirely new. Digital cameras use flash memory to store pictures, as do many MP3 players to store songs. The main problem with flash-based drives is larger capacities are very expensive and they have limited write cycles. These issues are being overcome though and flash memory has several advantages over hard disk drives like lower power consumption, more durability, more compact size, less heat dissipation, quieter operation and faster speed. The SSD reads 300 percent faster (53MB/s) and writes 150 percent quicker (28MB/s) than normal hard drives. As a result, multiple application programs can operate simultaneously and large volumes of data can be edited and reproduced more efficiently. Microsoft Windows XP will boot up 25-50% faster on the SSD than on other drives. Moreover, the typical 1.8-inch hard disk drive weighs around 50 grams; whereas the SSD is 20 to 30 grams lighter, depending on the package type. Mor
