This should speed performance, particularly for writing small random bits of data.įor notebook computer users the write cache is an interesting option, not supported at present by today’s generation of hybrid HDD (that contains some flash memory in addition to the hard disk drive) that can do read caching but not write caching.
As the buffer fills the older write data is transferred to the HDD in a sequential manner, optimized for HDD storage.
A write buffer stores writes of new data on the flash memory and speeds up writes that can fit comfortably on the buffer. Another interesting feature-and one that could be a benefit to many computer users is the use of 4 GB of the flash memory to act as a write buffer. This is because the operating system and pre-loaded software are all on the flash memory. The flash memory in this combo offers a faster boot up and launch of pre-loaded applications. The combination storage offering will combine 128 GB of NAND flash memory with either a 1 TB or 3 TB hard disk drive (HDD). The desktop Apple computers, the iMac and Mac mini, will include a combination of hard disk drives and flash memory called a Fusion drive. At the latest Apple product announcement, besides announcing the iPad mini Apple said that they were updating their Mac computer line-up as well.
