Solid/Magnetic/Optical Memory

Solid Memory

Solid Memory is also known as Solid State Storage (SSS) is a type pf computer storage which stores data electronically or magnetically like magnetic memory. For example USB drives, which act like hard disks, are a example of solid state memory. For example when you save your data on a USB it saves it on a little chip inside of the USB so next time when you need it, it loads up a lot faster.


1) No moving parts so nothing

much will happen if you drop it

2) Portable

3) Faster then a Hard disk drive

to access data

4) Can store up to 128GB +


1) Very expensive

2) Can Transfer viruses

3) Slower then main RAM on a computer

Magnetic Memory

Magnetic Memory is Non-Volatile which means it will Save what you've done. Magnetic Memory is one of the oldest types of technologies and ways to save the memory. Some Example Magnetic Memory is Floppy disks, Hard drives and Tapes. Magnetic Memory works when they are read by a moving head inside the disk drive. With Magnetic Memory there is a little laser that reads disc drive, so anything like scratches, fingerprints, hair etc will slow it down even more.


1) Cheap

2) Easy to carry


1) Moving parts will make the media slow and will not be able to read from or write

2) Magnet media Is very weak and therefore can be broken very easliy

Optical Memory

Optical Memory is any storage method that is read or written by lasers. These includes stuff like DVD's CD's etc. Also Optical Memory works when the disc is put in and read but the lasers if there is a slightest dust on it it might lag.


1) Storage is non volatile

2) Last longs with proper care

3) Cheap to make


1) Require special drives to read/write

2) Slower access time
