Storage Media
Paper
Advantages
-
Less energy required to store the paper just needs to be stored in a dry loctation - no server costs
Accessible - Doesn't need technology to access it, don't need to know how to use a computer
We use paper for things such as maps, shopping lists tickets for buses, trains and events etc.
Disadvantages
Very heavy and bulky to store; may need a large warehouse or archive whereas the same of amount for information could fit on a hard drive
Difficult to edit and update - the information could be inaccurate paper, ink and toner are expensive and have high environmental costs.
Time consuming to physically locate the correct paperwork - needs a robust filling system - whereas digital information can be retrieved in seconds
**
Even though we have GPS and satnav devices, many of us still use paper maps, either a road atlas in our cars or
an Ordnance Survey map when out walking or cycling. Mountain rescue teams take a very dim view of anyone
stranded without a backup paper map after the batteries in their GPS died or they didn’t have a phone signal to

Magnetic
Advantages
Large-capacity drives are available, holding many
terabytes
-
Good for servers, where special disks can spin at
15,000 RPM for fast access speed (a typical
consumer drive might spin at 7,200 RPM)
Disadvantages
Use mechanical parts, including motors, which can
eventually fail
The head can ‘crash’ into the platter if dropped,
destroying the drive
Consumer drives may spin at only 5,400 RPM – a

the disk, hovering just above the surface (but doesn’t touch the
surface). If the head does touch the surface, the drive can be ruined.

Optical
Advantages
-
-
No moving parts, so long-lasting if
stored correctly
Disadvantages
-
Recordable media can break down if stored in sunlight, heat
or humidity
Lots of plastic used – might be used only temporarily, especially
for CD-R and DVD+/-R
-
declined in recent years, and most consumer computers and laptops no
-
Home users can purchase writable (and rewritable) media such as CD-R and DVD-R or DVD+R (there are two
different ways that the data can be written to by the laser for DVDs, but most drives can read and write both
-
Solid State
Advantages
Very fast file access, boot times and software installation times
Very durable as no moving parts and not susceptible to shock or vibration - could last longer than mechanical drives when archiving data
Can get large sizes - a terabyte or more - allowing replacement for hard disks and shooting for 4k video
-
Solid state - a high end modern device and has many portable devices, use flash memory - there are no moving parts, hence the name solid sate this memory retains the data when switched off ( non-volatile) and cab be used in place of a mechanical drive.
