2. What is a SSD? SSD = Solid State Drive Data storage device
Solid state memory to store persistent data
NAND-based flash memory or DRAM
Same interfaces developed for HDDs

3. Advantages High performance Faster seek time No moving parts Low power
High reliability
Silent operation
Low power

4. Disadvantages More expensive than traditional HDDs Less storage space
Short lifetime

5. Comparison Solid State Drive Hard Disk Drive Access time <0.1ms

6. Why A SSD? Three things that dictate the speed of your PC/Server:
CPU, DRAM, and HDD

7. Applications Servers Desktop computers Laptops, ultrabooks
Mobile devices (smartphones and tablets)
Similar technology

8. Conclusion SSDs are more superior than HDDs
Due to the cost and the capacity limit, others may choose HDD over SSD
SSDs will replace HDDs
