Exploring solid state drives

  1. 1. E XPLORING S OLID S TATE D RIVES by: Michael Brown
  2. 2. Questions? <ul><li>What are SSD’s? </li></ul><ul><li>Do SSD’s have History? </li></ul><ul><li>Are they compatible? </li></ul><ul><li>What makes them Special? </li></ul>
  3. 3. Introduction <ul><li>W e all know hard drive’s by their mechanical features as well as their electrical, but what if we could run an operating system off nothing but electronical components. </li></ul><ul><li>S olid state drives are a technology that has undergone many an operation to weed out any and most complications that users have with standard mechanical drives. </li></ul>
  4. 4. HDD (Hard Disk Drives) <ul><li>Traditional hard disk drives use mechanical servos and actuator arms to scan magnetic media and then decode that information into an understandable language that operating systems can read. </li></ul>
  5. 5. What are SSD’s? <ul><li>A solid state drive is a high-performance plug-and-play storage device that contains no moving parts. SSD components include either DRAM or EEPROM memory boards, a memory bus board, a CPU, and a battery card. </li></ul><ul><li>Like HDD’s, solid state drives use binary, a series of 1s and 0s, to represent data. Except, a 0 is represented by a transistor that cannot accept an electrical current, while a 1 is represented by one that allows the flow of electricity. </li></ul>
  6. 6. Do SSD’s have History? <ul><li>As we all know technology doesn’t just happen over night. SSD’s originated in the 1970’s through government funded programs, but didn’t succeed. </li></ul><ul><li>Through to 2001 companies such as Quantum, Imperial Technology, SEEK Systems, and Solid Data Systems worked diligently to reintroduce SSD back into the market. They were successful! </li></ul>
  7. 7. Do SSD’s have History? Cont. <ul><li>In 2002 the terabyte SSD became commercially available. And from this point forward, research and development have taken even further initiative to mass fabricate SSD technology as well as make them faster and more reliable. Currently they are for purchase in many sizes and speeds. </li></ul>
  8. 8. Are they compatible? <ul><li>SSD’s conform to the same physical dimensions as hard drives, so they can fit in the standard drive bays and enclosures used by millions of computers. And SSD’s use the same Serial ATA (SATA) or IDE interface as hard drives, making them functionally identical. </li></ul>
  9. 9. What makes them Special? <ul><li>Power usage - Mechanical functions consume too much power on laptops. Now you can merely send a charge to and from transistors and retrieve faster results. </li></ul><ul><li>Speed - data access is nearly 50x’s faster simply because there are fewer steps in both reading and writing the data. </li></ul><ul><li>Ruggedness – Because of the minimal moving parts, SSD’s have been known to take a beating if damaged by either an impact or from being dropped, ultimately reducing drive crashes significantly </li></ul>
  10. 10. What makes them Special? Cont. Comparison Table (SSD vs. HDD)
  11. 11. Conclusion <ul><li>Solid State Drives have evolved over the years, and have slowly made their way into the consumer market. </li></ul><ul><li>The biggest draw back that I have found is that SSD technology has yet to become affordable. </li></ul><ul><li>If fabrication and affordability increase, we will definitely see bigger and better things through SSD technology. </li></ul>
