The conventional harddisks we are using today are using platter to store data, this type of harddisk will consume more power if compared to memory-ship based harddisk.

So, to reduce the power consumption and increase the read/write speed, Samsung is going to launch a flash memory based replacement for conventional hard disk drives. The solid-state disk (SSD) uses NAND memory chips instead of a mechanical recording system, this ensures lower power consumption and high data rates.

Quoted:
The first SSD with parallel Advanced Technology Attachment interface will ship in capacities up to 16GB. Such a device will feature sixteen 8Gb NAND memory chips and will cost approx. $900 with the current market prices of these chips.

One of the big advantages of SSD is its power usage, it requires only 5 percent of the power used by a normal HDD and it weights less than half as much. The SSD can read up to 57MB per second and write up to 32MB per second.
