This document discusses and compares different types of flash memory storage devices: solid state drives (SSD), memory cards, and USB flash drives. It provides details on what each type is, their specifications like size and storage capacity, advantages like portability and speed, and disadvantages like cost and durability. SSDs use flash memory and have no moving parts, providing faster access and transfer times than hard disks. Memory cards are used for media transfer between devices and come in formats like SD and microSD. USB flash drives simply plug into ports for convenient portable storage.

USB FLASH DRIVE

3. SOLID STATE DRIVES
 A solid state drive (SSD) is a storage device that
typically uses flash memory to store data,
instructions, and information.

4. Flash Memory Chips
 Flash memory chips are a type of solid state
media, which means they consist entirely of electronic
components, such as integrated circuits, and contain
no moving parts.

5.  Introduced in 1995.
 Capacity 1TB ( Maximum )
 High speed as compared to normal physical hard disk.

6. Available Sizes
 3.5 inches
 2.5 inches
 1.8 inches
SSDs are used in all types of computers including
servers, desktop computers, and mobile computers
and devices such as portable media players and digital
video cameras.

7.  Access times of SSDs are about 0.1 ms, which is more
than 80 times faster than a hard disk.
 Transfer rates of SSDs are faster than comparable hard
disks.
 SSDs generate less heat and consume less power than
hard disks.
Why SSDs are preferred over
Magnetic Hard Disk?

9. MEMORY CARD
 A memory card is
a removable flash memory device, that you
insert and remove from a slot in a computer, mobile
device, or card reader/writer

10. Types of Memory Card
 CompactFlash (CF)
 Secure Digital (SD)
 Secure Digital High Capacity (SDHC)
 Micro SD
 Micro SDHC
 xD Picture Card
 Memory Stick
 Memory Stick Micro (M2).

11.  Size normally 1.5 inches.
 Normally used for transferring media between
computer and cell phone.
 Memory cards enable mobile users easily to transport
digital photos, music, or files to and from
mobile devices and computers or other devices.

13. USB Flash Drive
 A USB flash drive, sometimes called a thumb drive, is
a flash memory storage device that plugs
in a USB port on a computer or mobile device

14. Convenient source of storage
 USB flash drives are convenient for
mobile users because they are small and lightweight
enough to be transported on a keychain or in a
pocket.

15. Advantages
