3. 3. What is a Solid-State Drive? • A SSD (solid-state drive or solid-state disk) is a storage device that stores persistent data on solid-state flash memory. • No moving parts in SSD compared to a hard disk drive. • Connections: IDE, SATA, mSATA, ExpressCard, PCI Express • Hybrid drive
4. 4. Architecture of SSD SSD consists of basically three elements: • SSD Controller • SSD Flash • SSD Interface
5. 5. Advantages of SSDs  High performance – significantly faster than a standard HDD  Faster seek time – up to 60x faster than HDD  Lower power – Lesser power consumption ,cooler operation  Silent operation  Lighter weight – perfect for portable devices.  Ability to endure extreme shock, high altitude, vibration and extremes of temperature.  Immune to magnets.
6. 6. Disadvantages of SSDs  They are more expensive than traditional hard drives.  They currently offer less storage space than traditional hard drives.  Solid-state drives slow down as you fill them up. Fill your solid-state drive to near-capacity and its write performance will decrease dramatically. The reason why lies in the way SSDs and NAND Flash storage work.
7. 7. Where SSDs are found: Solid-State Drives • Servers • Desktops • Laptops • HD camcorders • Smart TV • CCTV Digital Video Recorder (DVR) • Gaming Consoles Solid-State Storage • Smart phones • USB flash drives • SD and Micro SD cards • Tablets • MP3 players
