Samsung to show first hybrid hard drive prototype
Samsung has announced that it will show the
first commercial hybrid hard drive prototype that combines
traditional magnetic platters and NAND flash memory at the WinHEC
conference next week. The prototype drive will sport between 128 MB and
256 MB of high-speed OneNAND flash memory, which promises 108 MB/s read
and 18 MB/s write speeds, as well as a 300 MB/s Serial ATA interface
with support for Native Command Queuing. Samsung's prototype is based on Microsoft's
ReadyDrive, a technology that caches parts of the operating system
along with commonly used applications to quicken startup time, increase
performance, and lower power consumption.
According to Samsung, the new prototype cuts down boot times by up to 25
seconds and can increase battery life by a whopping 10%. To achieve
these kinds of power savings, the drive spins up "only a few seconds"
every 10 to 20 minutes to transfer data to or from the cache. Samsung
plans to ship the first commercial hybrid hard drives in January 2007,
coinciding with the expected launch of Windows Vista. Intel's Santa Rosa
mobile platform is also due to harness
hybrid hard drives when it ships in mid-2007. Thanks to Engadget
