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.
