Solid State Drives are the new solutions to permanent storage on devices from Personal Computers (PC) to PDA's (Personal Digital Assistant). They are much faster, lighter, contain no moving parts, smaller, no noise, shock resistant but little expensive. ;) They are built with memory chips (Flash Memory). This Presentation cover all of the advantages, disadvantages and comparison about SSD vs HDD.

3. What is SSD?
 Short for Solid-State Drive or Solid-State Disk, SSD is a drive that uses
non-volatile NAND Flash memory as a means of storing and accessing data,
much like computer RAM.
 SSD has no moving parts. 
 SSD uses SATA (Serial Advance Technology Attachment).
 No Defragmentation Needed. 
 Retains DATA without Power Supply.

6. 1. FASTER
 Access Speed Of 35 µs to 100 µs
 Instantaneous Data Access
 100 Times faster
 Quicker OS Boot Up
 Faster File Transfer, Read & Write
 Lower Latency

7. 2. RELIABLE
 Non-Mechanical Design
 NAND Flash Drives Mounted On PCB
 No Moving Parts
 Shock Resistant
 Immune To Magnetic Field

8. 3. LIGHTER
 Less Weight About ~ 75g
 No Spindle, Platters & Read-Write Head
 Lighter Than HDD (~750g)
 Easiness To Carry (Mobility)

9. 4. LOW POWER CONSUMPTION
 Uses Significantly Less Power
 SSD At Peak Load (2W)
 HDD At Peak Load (6W)
 Better Battery Life
 Less Power Strain
 Cooling Environment

10. 5. LESS HEAT
 Small Power To Operate
 Significant Reduction Heat Emission
 Energy Efficient
 Less Damage Due To Heat

11. 6. LOW NOISE
 No Spindle
 No Read-Write Head
 No Platters
 No Moving Parts
 Silent Operation

12. 1. HIGH COST
 Expensive Than HDD 
 Uses Flash Memory
 Manufacturing Cost
 Assembly is Complex
 Low Market Share

13. 1. LOW STORAGE CAPACITY
 A Single NAND Flash Memory Can Hold From
1GB to 64 GB
 Maximum Of 1GB For Notebooks
 Maximum Of 4GB For Desktops
 Anything over 512GB is Beyond The Budget
of Normal People 

14. 1. SHORT LIFE SPAN
 SSD’s wear out over TIME
 Each Cell in a FLASH Memory can be written
to and Erased a limited number of time
The More you USE the FASTER it will FAIL

15.  Desktop Computers
 Laptops
 Embedded Systems
 Servers
 Digital Camera

16.  Hard drives win on price, capacity, and
availability
 SSDs work best if speed, ruggedness, noise, or
fragmentation (technically part of speed) are
important factors to you.
 If it weren't for the price and capacity issues,
SSDs would be the hands-down winner.
