Okay, this may be a slightly ‘geeky subject’ but I enjoyed compiling this and hope you enjoy reading it!…
Computers are indisputably an integral part of not only modern business but modern life in general. Although the internet is an excellent tool for the sharing of information and media through email, file sharing services and Peer 2 Peer- physical media is essential for the distribution and safe storage of files of all sorts. Much like the computers themselves, media storage devices and methods have developed in line with technological progress and are consistently growing in terms of memory capacity, flexibility and speed whilst decreasing in physical size.
In honour of the often underappreciated world of recordable media we’ve taken a look at the changes this industry has undertaken from its first incarnation for personal use through to the modern day:
The Floppy Disk
Storage capacity (formatted) – From 79.7kb (8 inch 1971) up to 200mb (3 ½ inch 1999)
Year of commercial launch- 1971
The floppy disk ruled the roost for almost three decades; from its initial 8 inch form unveiled by IBM in 1971 through to the 3 ½ inch sized floppy which dominated until the late 1990s. The floppy disk had no substantial competition for the majority of its time and despite challenges from formats such as the Iomega Zip Drive; remained the most popular form of data storage and an essential piece of office equipment until the recordable compact disk became affordable enough to become its successor. The floppy disk is now virtual obsolete with floppy disk drives (FDDs) absent for new computers. It is however possible to get external USB floppy disk drives if nostalgia kicks in.
CD-R and CD-RW
Storage capacity- 650mb-870mb
Year of commercial launch- 1988/90
The appropriate hardware required for saving to a Recordable CD or CD-R was initially prohibitively expensive to the extreme. In 1990 for instance the most affordable means of writing to a CD came in at around £25,000 for a hugely bulky piece of equipment. It was a further 5 years until the first CD recorder available for under $1000US was made available. From that point however, the hardware rapidly became more affordable until the point where CD-Rs and their re-writable counterparts overtook floppy disks as the storage medium of choice before the end of the 21st century. The major benefit of the recordable CD compared to the floppy disk was a combination of the considerably larger storage capacity and compatibility with audio and video CD players. The launch of the CD-RW secured the usurping of the floppy disk as it offered a re-writable alternative to the conventional CD-R and in doing so served to rectify the recordable CD’s major perceived flaw (that it could
only be recorded onto once).
The recordable CD grew to such an extent (not least due to the advent of file sharing websites allowing users to download music from the internet and create their own audio CDs) that in 2001 sales of recordable CDs outstripped recorded CDs for the first time (182 million compared to 172 million). This dominance continued to grow until the recordable DVD came along and things got a little more interesting.
This part of the story is a little less clean cut than the previous instalment, not least because the CD-R is still with us (unlike the floppy disk for the most part). Despite the continued usage of CD-Rs and CD-RWs they are no longer the most prevalent means of removable data storage, that accolade is divided between a number of different types of media. It is fair to say however, that the rightful successor to the recordable CD is the recordable DVD given the close similarities between the two forms and that the CD compatible DVD reader/recorder is to be found in the vast majority of modern computers.
Recordable DVD
Storage capacity- 4.7GB-8.5GB
Year of commercial launch- 1997
The DVD was first unveiled in Japan in 1996 as a medium for pre-recorded video and the concept was gradually rolled out internationally. In 1997 Pioneer developed the DVD-R format which began the process of bringing home recording to the masses. The major upside of the DVD over the CD is the considerably more substantial memory capacity, whilst the standard CD can store 700MB of information; the standard DVD is capable of storing 4.71GB. This marked difference in capacity is well demonstrated by their different uses in the entertainment industry, i.e.: the CD is used for music whilst the DVD caters for video.
The recordable DVD is useful for backing up data, transferring large files and also converting and storing films and computer games for use in other DVD compatible devices. Despite the availability of re-writable DVDs however, it is by no means the most popular form of portable data storage for day to day use.
USB Flash Drive
Storage capacity- 8MB (2000) 64MB-256GB (Present day)
Year of commercial launch- 2000
The USB or Universal Serial Bus is a means of communication between a computer and all manner of peripherals and other devices. This small, rectangular port serves as a way to connect a mouse or keyboard to a computer as well as serving as a power source and means of data connection for a whole host of external devices. One of the most simple and common of these devices is the USB flash drive.
The very first USB flash drives were launched in 2000 and offered storage capacity up to 8MB,the capacity of top end flash drives today is up to 256GB: showing an absolutely vast growth in the industry. The device, also known as the pen drive is the closest replacement to the floppy disk, in that it is simply inserted-the data transferred-then it is removed, whereas the CD and DVD tend to take longer to complete the saving process. Flash memory is now present in a whole host of other portable items which require data storage.
The Modern Face of Portable Media Storage
New means of experiencing media such as the IPod, MP3 and MP4 player have brought about a serious shift in the world of portable data storage. This change is also highly reliant upon the USB port found in all modern computers. Not only do we now have the option to plug in a small device and quickly transfer information onto it for storage purposes, but also to transfer files directly from a computer onto a personal entertainment device which ultimately means that a huge number of the devices we use for portable data storage, double up as autonomous devices in their own right…a huge leap indeed from the 8 inch floppy disk.
