Marvell HyperDuo
Storing all consumer data on SSDs is costly and using the hybrid approach of manually combining an HDD and SSD doesn’t offer a true solution for achieving consistent performance acceleration in applications like gaming, video and rich media or I/O intensive programs.
Marvell HyperDuo solves this dilemma. A breakthrough embedded technology for 6Gb/s SATA controllers, HyperDuo is configured with at least 1 hard disk drive (HDD) and up to 3 solid state drives (SSD). By embedding automated tiering technology into the chipset that goes into the world’s leading motherboards, home network attached storage (NAS), set-top boxes and desktop HBAs, HyperDuo achieves immediate performance value from day one. The technology uses intelligent algorithms to automatically migrate hot data to SSDs, while enabling all data to be safely stored on larger capacity SATA HDDs. Thus HyperDuo enables near-SSD performance at HDD capacities.
Features:
Enables over 80% of SSD performance at less than 1/3 the cost
RAID: RAID 0/1 firmware running on ARM-based CPU
Enables two modes:
Safe Mode: Automated mirroring from SSD to HDD for maximum protection
Capacity Mode: SSD capacity augments the hard drive to optimize cost efficiency
GUI: Flexible, intuitive administration console for power users
For 88SE9230 series and higher:
Multiple SSD’s (up to 3 SSDs + 1 HDD) to scale to higher IOPS, throughput, and capacity
Concurrent HyperDuo with RAID 0/1 on HDDs for capacity and data protection (ie. 2 SSDs + RAID0/1 on dual HDDs)
On-the-fly AES 128/256-bit encryption for connected SATA SSD/HDD devices
Once the two drives are set up, the card itself will detect frequently used data (hot files) and move them to the SSD part. However, there's also a software application that allows users to proactively move any portion of the data to the SSD, as long as it's smaller than the total capacity of the SSD. For example, you can choose to move an entire Office suite if you want Word, Excel, and so on to load really fast. And by "moving," all you have to do is add that suite to the list of prioritized applications; there's no actual data copying/moving involved from the user's perspective.
In essence, this solution allows users to use the SSD most of the time while keeping the hard drive as just a storage space for idle files and documents, which don't need to load very fast. In other words, most of the time, you use the computer as though it only had an SSD drive, hence the much-improved performance. The demo showed that the read and write speeds of the hybrid solution, in Capacity Mode, are basically those of the SSD drive. The larger the SSD is, the less frequently you'll need to access the hard drive.
