  1. Solid State Device Technology Mayuresh Varerkar ECEN 5613 Current Topics Presentation March 30, 2011

  2. Topics- Presented and Researched • Topic to be presented • Solid State Device Technology • 5 more Relevant and Interesting Topics • Intel Atom Processor • Avoiding malloc()/free() APIs in military and aerospace embedded code • System awareness improves SOC power management • Embedded Multimedia Card (e.MMC) • Embedded Microcontroller Upgrade Solid State Drive Technology - Mayuresh Varerkar

  3. What is a SSD ? • SSD stands for Solid State Drive • SSD is a data storage device which stores data in microchips • No moving parts but same interface as hard disks • Quieter, Lower access time and latency • Uses NAND-based flash memory Source: http://www.followsteph.com/2008/02/14/solid-state-drive-ssd-review/ Solid State Drive Technology - Mayuresh Varerkar

  4. Architecture of SSD Source: http://www.storagereview.com/ssd_architecture Solid State Drive Technology - Mayuresh Varerkar

  5. Features of SSD • Improved Performance: • Transaction Workload- 1 SSD equivalent to 100 Hard Drives • Input/ Output Per Sec – 80,000 IOPS compared to 350 for HD • Space Reduction: • Fewer Drives • Power Saving: • Less cooling cost due to fewer drives • Enhanced Reliability: • No head crash as in HDs Solid State Drive Technology - Mayuresh Varerkar

  6. SSD Specifications (Toshiba) • Capacity: 64GB – 512GB • Interface: Sata 2.6 • Voltage: 5V or 3.3V • Maximum Read and Write Speed: 220MBps and 180MBps respectively • Mean Time to Failure: 1 million hours Solid State Drive Technology - Mayuresh Varerkar

  7. Applications of SSD • Database and OLTP • Data in demand stored in SSDs • Email • Email servers for quick responses • Virtualization • Reduction in boot storms and login storms • Cloud Computing • Incorporated in storage architectures to service multiple users Solid State Drive Technology - Mayuresh Varerkar

  8. SSD in Embedded Systems • Growth of HD content on Embedded Devices • Required higher bit rate for fast access of data - SSDs • Digital Cameras and Recorders • Make use of Flash Memories which are fast but limited in capacity • SSDs provide higher capacity along with good speed • Portability in Embedded Devices • Currently make use of Hard Disks for large capacity storage • SSDs would provide similar capacity with greater portability Solid State Drive Technology - Mayuresh Varerkar

  9. SSD in Embedded Systems • Moving Parts with Capacity • Embedded Devices require minimal moving parts -rugged use and avoid disturbance to closely spaced components • Power Consumption in Embedded Systems • One of the major considerations for hand held devices • SSD consumes very less power due to fewer drives • Improves battery life Solid State Drive Technology - Mayuresh Varerkar
