Samsung’s award-winning new Hybrid Hard Drive (HHD) combines a hard disk drive with OneNAND™ Flash memory, representing a next-generation approach to storage that offers faster boot and resume times, increased battery life and greater reliability compared to traditional magnetic media technology, an easy way to speed up Vista. The OneNAND Flash from memory leader Samsung functions in the HHD as a write cache during normal operation, saving power and reducing the chance of drive failure. It also acts as a read cache during boot/resume and when specific applications are launched to accelerate system performance. |

Samsung’s OneNAND Flash is an optimal choice for the HHD as the result of its industry-leading read/write performance and the superior reliability of its SLC cell structure. This single-chip flash combines the ultra-high density of NAND with the simplified interface of NOR at very attractive price points. The flash memory is integrated into the hard drive architecture, storing write data and thus enabling the spindle motor to be kept idle most of the time. When this flash-based write cache is filled, the data is automatically written to the disc. The HHD is enhanced with Windows® Ready- Drive™, one of the new performance features in the upcoming Windows Vista™ operating environment. The Samsung HHD is a 2.5-inch drive with 256 megabytes of flash memory. |
| The OneNAND Flash-based write cache within the HHD allows the platters to be kept idle 99% of the time; they spin briefly when this cache is full and the data is then automatically saved to the disc. Besides reducing power and increasing reliability, the inclusion of solid-state memory in the drive significantly cuts boot and resume times. |

HHD Offers Cost-Saving Features
Since the HHD’s platters are idle 99% of the time, they are much less susceptible to shock damage. In addition, the HHD operates at a lower temperature than a traditional hard drive, which also reduces the likelihood of damage. This helps improve reliability by a factor of five, reducing the incidence of hard drive failures so common in mobile PCs and also lowering repair and maintenance costs. Another advantage is 70-90% less power consumption, which extends battery life by 30 minutes before a recharge is needed.
Better Responsiveness - Speed Up Vista
The HDD’s nonvolatile flash cache can be populated with key data before a shutdown or suspend, which reappears within a second or less after a resume or reboot. By writing portions of the S4 suspend file to this cache, resume times can be reduced by up to 50%. Keeping key portions of the operating system resident in the cache can also reduce start-up time by 50%.
Application Acceleration Can be Customized
The quick responsiveness resulting from the OneNAND Flash cache can be applied to specific applications selected by an OEM or end user. These applications can be “pinned” into the HHD’s cache, improving responsiveness by a factor of three to four. This enables OEMs to determine which features – such as media screens, support information or others – they would like to make instantly available to end users.
The Future of Flash for Storage
The HHD demonstrates the expanding use of NAND flash for storage applications. While flash memory brings increased speed, performance and reliability to mobile PC storage, another advantage is the promise of ever-greater density within a small space. NAND flash density has been doubling every year, compared to a doubling every two years for magnetic storage. As densities continue to climb while costs decrease, the use of NAND flash for storage solutions will undoubtedly grow well beyond the current level. |
