storage
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,
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
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.
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.
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
