WD's hybrid technology works in conjunction with the PC operatingsystem to deliver higher performance than current hybrid offerings while minimizing NAND wear to allow the use of less expensive MLC NAND.
Using a combination of HDD and flash memory in either a hybrid HDD or a dual storage notebook computer, where frequently used data (and possibly the operatingsystem and application software) is kept in the flash memory, while the bulk of user content is kept on the HDD, has been shown to provide about 80% of the performance improvements of a pure SSD-based computer.
These approaches can combine a smaller SSD that stores the operatingsystem and applications and a larger HDD that is used for user data, or a hybrid HDD that has flash memory inside a HDD that is used to store frequently accessed data on the flash with less used data kept available on the HDD.
