2. Abstract
 A solid-state drive (SSD) (also known as a solid-state
disk or electronic disk, though it contains no actual "disk" of any
kind or motors to "drive" the disks) is a data storage
device using integrated circuit assemblies as memory to store
data persistently.
 SSD technology uses electronic interfaces compatible with
traditional block input/output (I/O) hard disk drives, thus permitting
simple replacement in common applications.
 Also, new I/O interfaces like SATA Express are created to keep up
with speed advancements in SSD technology.
 SSDs have no moving mechanical components.

7. Overview of HDD
 Magnetic Storage Media.
 Stores data in Magnetic Disks.
 Read/Write Head for Storing and Retrieval of data.
 Spindle and Motor to rotate disk.
 Actuator arm.
 Fragile Disk makes it prone to
damage.

8. Overview of HDD (contd.)
 40% annual increase in capacity of HDDs.
 But Only 2% annual increase in random I/O performance.
 Failure in today’s requirement.

9. Overview of SSD
 NAND-based Flash Storage Media.
 Stores data in Multi-Level Cell(MLC) NAND.
 Performance and Power consumption enhancement.
 Unlike HDD, SSD has no moving parts.

14. HDD vs. SSD
 Startup-up time (Windows 7): 22 seconds(SSD), 40
seconds(HDD).
 Data read-write speed: 510-550 MB/second(SSD), 50-150
MB/second(HDD).
 Noise: Silent(SSD), Noise from moving parts(HDD).
 Temperature control: No cooling system(SSD), Require if
temperature exceed it limit(HDD).
 Excel file open speed: 4 seconds(SSD), 14 seconds(HDD).Dept. of CSE, NCET
