storage

1. RAM

   • RAM (pronounced ramm) is an acronym for random access memory, a type of computer memory that can be accessed randomly
   • Silent: since there are no moving parts RAM operation is completely silent.
   • Volatile: a power outage will cause irrecoverable data loss,

2. ROM

   • Pronounced rahm, acronym for read-only memory, computer memory on which data has been prerecorded
   • The Custom ROMs takes up less space than most Stock Roms and also allow you to integrate SD storage fully.
   • it is easy to scratch the surface of the CD and it won't work properly after that

3. Solid state drive

   • A solid-state drive (SSD) is a nonvolatile storage device that stores persistent data on solid-state flash memory.
   • The SSD drive has no moving parts. It uses flash memory to store data,
   • Smaller storage capacity than magnetic hard disks.

4. Hard disk drive

   • disk drive used to read from and write to a hard disk.
   • 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
   • Hard disks can crash which stop the computer from working.

5. Optical CD, DVD, Blu-ray

   • 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.
   • Mass storage capacity (on the order of gigabytes)
   • Slower to access than the hard disk
