| Storage Mediums |
Many know about these already but for those that don't here they are.
This page will get updated when i get ahold of different storage mediums.
1) In the first picture you see a 3.5" floppy(diskette) and a cd, the floppy
is there for size comparison.
The CD disks storage ranged from roughly 650Mb to 1.2Gb on
a sony drive that wasn't too common, normal sizes were 650 and 700Mb.
2) Picture two contains different sized floppy discs.
From left to right, aka oldest to newest:
The earliest floppy disks, invented in the late 1960s by David L. Noble at
IBM, were 8" (200 mm) in diameter.
IBM introduced the diskette commercially in 1971.
This floppy has a max capacity of 1.2Mb and is then a double-density
floppy.
In 1976 Shugart Associates introduced the first 5.25" (5.¼") FDD and
associated media.
The max they could
store was 1.2Mb of storage.
This was a high-density floppy's.
By making a notch on the left side of the floppy you could double the
storage for drives that could not use the two sides at once.
The two to the right are the 3.5" standards.
There is minor changes to these two that separates them.
The first one can store up to 1Mb unformatted
and about 720Kb formatted.
Were called a double-density floppy.
The floppy has one hole less on the right side than the 1.44Mb variant.
The last floppy is the most recent one.
2Mb unformatted and 1.44Mb
formatted, also called a high-density floppy.
The Distribution Media Format (DMF) was later introduced permitting 1680 Kb
to fit onto an otherwise standard 3.5" floppy, utilities appeared allowing
floppies to be formatted to this capacity.
There was also a 2.88Mb sized floppy and drives but these were not too
common, was called a extended-density floppy.
3) Cassette tape.
Most used these for music and sound in all type of media but they were also
used for storage in less expensive computers like the Commodore 64 among
others in the 70's and 80's.
4) SyQuest 44 MB removable disk cartridge.
SyQuest Technology, Inc., now known as SYQT, Inc., was an early entrant into
the removable hard disk market for personal computers. The company was
started in 1982 by Syed Iftikar; it was named partially after himself
because of a company meeting wherein it was decided that "SyQuest" ought to
be a shortened name for "Sy's Quest". Its earliest products were 3.9"
(100mm) removable hard drives, and 3.9" (100mm) ruggedized hard drives for
IBM XT compatibles and military applications.
The disk itself is like a hard drive's platter.
The last size of these from SyQuest were at 4.7Gb just like todays DVD's.
5) The Zip drive is a medium-capacity removable disk storage system that was
introduced by Iomega in late 1994.
Originally, Zip disks launched with capacities of 100 MB, but later versions
increased this to first 250 MB and then 750 MB.
The format became the most popular of the super-floppy type products which
filled a niche in the late 1990s portable storage market.
However it was never popular enough to replace the 3.5-inch floppy disk nor
could ever match the storage size available on rewritable CDs and later
rewritable DVDs.
USB flash drives ultimately proved to be the better rewritable storage
medium among the general public due to common availability of USB ports
built into most models of personal computer.
Zip drives fell out of favor for mass portable storage during the early
2000s.
The Zip brand later covered internal and external CD writers known as
Zip-650 or Zip-CD, which had no relation to the Zip drive. |
