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 March 24, 2011Solid State Drive Technology - Mayuresh Varerkar2

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 March 24, 2011Solid State Drive Technology - Mayuresh Varerkar3 Source: http://www.followsteph.com/2008/02/14/solid-state- drive-ssd-review/

4. Architecture of SSD March 24, 2011Solid State Drive Technology - Mayuresh Varerkar4 Source: http://www.storagereview.com/ssd_architecture

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 March 24, 2011Solid State Drive Technology - Mayuresh Varerkar5

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 March 24, 2011Solid State Drive Technology - Mayuresh Varerkar6

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 March 24, 2011Solid State Drive Technology - Mayuresh Varerkar7

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 March 24, 2011Solid State Drive Technology - Mayuresh Varerkar8

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 March 24, 2011Solid State Drive Technology - Mayuresh Varerkar9
