A hybrid hard drive (HHD) is a standard hard drive fitted with a large buffer or memory cache that does not require a spinning disk to record data. This “non volatile” form of flash memory is included in the HHD in increments of up to one gigabyte, resulting in a hard drive that basically functions to back up the memory cache.
The “platters,” or discs in a hybrid hard drive are thus required to crank up and spin only when the buffer memory is filled or when the computer operator is moving extremely large files around. The result is that for normal computer operators, the hard drive is actually spinning a fraction of the time that the computer is in operation, compared with one hundred percent of the time for a standard hard drive.
The advantages of this format are several. Because the HHD is actually turning only ten percent of the time or less, the computer consumes far less power and generates far less heat. These features are particularly valuable in a laptop that is operating on battery power. It is also true that laptops have been somewhat limited in the video horsepower they can handle due to heat generation. Any reduction in heat for...
