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. Architecture of SSD
SSD consists of
basically three
elements:
• SSD Controller
• SSD Flash
• SSD Interface

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. 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.
