3. Introduction
 A solid-state drive (SSD) is
a data storage
 Circuit assemblies as memory to
store data persistently.
 SSD technology uses electronic
interfaces compatible with
traditional block input/output
(I/O) hard disk drives.
Brief introduction SSD.. Form force

4. Mechanism SSD
Concept Storage generation
HDD
 The key components of an
SSD are the controller and
the memory to store the data
 The primary memory Flash memory
component in an SSD had
been DRAM volatile
memory
 Other components play a less
significant role in the
operation of the SSD

5. Attribute SSD (Solid State Drive) HDD (Hard Disk Drive)
Power Draw Less power draw, More power draw
CostSSD vs. HDD Expensive Only around $0.10 per
gigabyte.
Capacity Not larger than 512GB Not larger then 2TB for
for notebook size notebook size drives
drive Around 40 second
Boot up time Around 22 second Spinning can be
Noise No moving part heard
Still some vibration
Vibration No vibration HDD doesn’t produce
Heat Produced It produce little heat much heat, but it will
Because there is lower have a measurable
power draw amount more heat
than an SSD due to
moving parts and
higher power draw

6.  Failure Rate  Mean time between  Mean time between
failure rate of 2.0 failure rate of 1.5
million hours million hours
 File Copy / Write Speed  Generally above 200  The range can be
MB/s and up to 500 anywhere from 50 –
MB/s for cutting edge 120MB / s
drives
 Encryption  Full Disk Encryption  Full Disk Encryption
 File Opening Speed  Up to 30% faster than  Slower the SSD
HDD
 Magnetism Affected  An SSD is safe from  Magnets can erase
any effects of data
magnetism

7. Advantages
 Reliability
in portable environments
and no noise
 No moving parts
 Faster start up
 Does not need spin up
 Extremely low read latency
 No seek time (25 us per page/4KB)
 Deterministic read performance
 The performance does not depends on the
location of data

8. Disadvantage
 Cost significantly more per unit capacity
 Limited write erase time
 Slower write speeds because of the erase
blocks are becoming larger and
larger
 for low capacity flash SSDs
 low power consumption
 heat production when in active use
 High capacity SSDs may have significant
higher power requirements

9. Drive read performance

10. Effect over computer
system
 SSD is more faster then any other data
storage devices
 Read / Write speed of SSD is 30% faster
then HDD means if you need a faster
workstation for your work this device
make is revolution on your personal
computer
 It makes a noise free system and save 20%
to 50% energy.
 SSD does not create heat. This is very
good for processer.
