Thickness of notebooks and tablets is reducing by the day so it is important for component makers to change design of their components in order to cater to the hot ultra-thin segment. Western Digital understands this and has therefore developed a 5mm thin hard disk drive featuring hybrid technology. Thanks to its slim profile, the WD hybrid drive can be integrated into today’s thinnest notebook PCs, providing high-capacity storage and robustness while featuring instant-on and application performance similar to solid state drives.
WD’s innovative hybrid technology pairs MLC NAND flash storage for fast SSD-like data throughput and instant-on responsiveness with magnetic disks for efficient, high-capacity storage.
Similar to the practice of multi-million dollar enterprise systems, WD’s hybrid technology utilizes the concept of tiered storage. Data accessed most frequently (often referred to as ‘hot’ data) is managed using speedy NAND flash to ensure fast response times, while data accessed less often (‘cold’ data) resides on the robust magnetic disks.
The tiered design of hybrid hard drives, compared to current dual-drive solutions, also provides a redundancy benefit for users. The magnetic disk backs up all files residing in the NAND, protecting the user from inevitable NAND wear and preserving it for the more hot data handling.
WD’s hybrid technology works in conjunction with the PC operating system to deliver higher performance than current hybrid offerings while minimizing NAND wear to allow the use of less expensive MLC NAND.
