what is a ssd
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

features of ssd
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

applications of ssd
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

ssd in embedded systems
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

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
