Solid-state drives (SSDs) are storage devices that use solid-state flash memory instead of rotating disks. SSDs have no moving parts, faster access times than hard disk drives, lower power consumption, and can withstand physical shock better than hard drives. However, SSDs are currently more expensive than hard drives and offer less storage capacity. SSDs are commonly found in servers, desktop and laptop computers, camcorders, gaming consoles, smartphones, and other portable electronic devices.

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.
