RAM
1. RAM (pronounced ramm) is an acronym for random access memory, a type of computer memory that can be accessed randomly
2. Silent: since there are no moving parts RAM operation is completely silent.
3. Volatile: a power outage will cause irrecoverable data loss,
ROM
1. Pronounced rahm, acronym for read-only memory, computer memory on which data has been prerecorded
2. The Custom ROMs takes up less space than most Stock Roms and also allow you to integrate SD storage fully.
3. it is easy to scratch the surface of the CD and it won't work properly after that
Solid state drive
1. A solid-state drive (SSD) is a nonvolatile storage device that stores persistent data on solid-state flash memory.
2. The SSD drive has no moving parts. It uses flash memory to store data,
3. Smaller storage capacity than magnetic hard disks.
Hard disk drive
1. disk drive used to read from and write to a hard disk.
2. More affordable than SSD: One of the primary advantages of a hard disk drive is that it is more affordable than SSD in terms of dollar per gigabit
3. Hard disks can crash which stop the computer from working.
Optical CD, DVD, Blu-ray
1. Data is recorded by making marks in a pattern that can be read back with the aid of light, usually a beam of laser light precisely focused on a spinning optical disc. An older example of optical storage that does not require the use of computers, is microform.
2. Mass storage capacity (on the order of gigabytes)
3. Slower to access than the hard disk
