Hybrid Hard Drive Aims to Extend Laptop Battery Life
Samsung has built a new hybrid hard disk drive. This new hard disk has a flash memory chip built into the drive. A traditional hard disk will spin once the computer is turned on and will continue to so until the computer is switched off. This causes hard disk drives to be power hungry. In the case of laptops, this eats into the battery life very quickly.
Samsung Electronics is the world leader in advanced memory technology. It's OneNAND flash memory is incorporated into the design of Microsoft's prototype Hybrid Hard Disk Drive. Since 2003, Microsoft and Samsung have been working together to produce ultra-low power disk drives for laptops.
Traditionally, the disks spin whilst data is written to and read from. The flash memory has a write buffer and a boot buffer. Data is written to the flash memory and when the write buffer becomes full the disks are spun and is written to the drive from this buffer. The mechanical drive is spun down and is kept idle whilst data is written to the flash memory. This saves considerable power.
The CPU is able to read from and write to the flash memory at a higher rate. Booting up the computer is a much faster process as the CPU does not need to wait for the drive to be spun up to the optimum speed.
Consumers can expect a considerable power saving by using these hybrid hard disk drives.
