Buying Data Storage Media
One of the most important requirements for any consumer is technology that provides a medium for the purpose of placement, storage and retrieving of data. The medium is a component used in conveying messages. The messages on a storage medium are in the mode of data that is poised for use as required. The more pictures you take and the more music and videos you download, the more storage you need.
Most consumers opt for a digital camera able to record to SD cards because this type of camera is very affordable. SD cards make this type of small, portable and handheld camera cheaper. These cards have enough storage for videos.
An SD card also happens to be very hard wearing. There are no moving parts and this allows for a longer live. This is made possible by the flash based retrieval and storage arrangement. These cards also have a higher resistance than DV tape and hard drives to temperature changes.
You will find SD cards make video shot simple to prep in mix down, sort and sift due to software and easy indexing and searching.
There are some negatives regarding SD. For example there is a need for a deep bag of additional cards for video recordings of a few hours daily. 8GB SD cards have sufficient storage to keep approximately one hundred and twenty minutes of video. 32GB SD cards keep about six hours of standard resolution video. High quality uses up more storage.
These cards keep in check large amounts of video on small areas but do affect the quality of video. You tend to get the lowest video quality from digitals.
SD cameras do not give the high quality of lenses on more expensive models. This is seen in low light and tight zooms.
CD / DVD
Consumers have a wide variety of optical drives to choose from. Some only read CDs but can not write new data. Some drives have CD-R (recordable) and CD-RW (rewritable). DVD drives are sold in a similar way. Some DVD drives are DVD+R/-R while others are DVD+RW/-RW. There are drives that can read + and – formats i.e. they are dual format. When you buy a disc it must be compatible with your exact drive.
The life of a CD or DVD could be anything from twenty to two hundred years. It all depends on what the manufacturer purports. A big plus for optical discs is the resistance of damage caused by electromagnetic that is common on other means of bulk storage and hard drives. It is important to note that optical discs must have their reflective side protected and the discs must not be exposed to the extremes of temperature.
External Hard Disc
If your computer can not hold more drives then an external hard disc is useful due to the extra provision of storage space. Another big positive for this kind of storage is portability. However, there also some negatives.
Due to its portability, the external hard drive is easy to steal. All it takes is to unplug the tiny device and it is gone.
Some external hard drives are bundled with software by the manufacturer. To release storage taken up by the surplus software the device must be formatted.
As this type of device is mainly out in the open it is easy to damage by shock. For example, knocks and spilled drinks could easily damage the platter.
