Media Storage Devices
Storage Devices are the data storage devices that are used in the computers to store the data. The computer has many types of data storage devices. Some of them can be classified as the removable data Storage Devices and the others as the non removable data Storage Devices.
The data Storage Devices come in many sizes and shapes. And more over the technology used for the storage of the data over them is also altogether different. The storage devices are one of the most important components of the computer system. The memory is of two types; one is the primary memory and the other one is the secondary memory.
The primary memory is the volatile memory and the secondary memory is the non volatile memory. The volatile memory is the kind of the memory that is erasable and the non volatile memory is the one where in the contents cannot be erased. Basically when we talk about the data storage devices it is generally assumed to be the secondary memory.
The secondary memory is used to store the data permanently in the computer. The secondary storage devices are usually as follows: hard disk drives – this is the most common type of storage device that is used in almost all the computer systems. The other ones include the floppy disk drives, the CD ROM, and the DVD ROM. The flash memory, the USB data card etc.
The storage devices are used to record the data over any storage surface. The memories may also be of different types depending upon the architecture and the design like the optical data storage memory, magnetic media storage and the mechanical storage media etc and also the flash memory devices etc.
The storage devices are actually defined as the peripheral unit which holds the data like the tape, disk, or flash memory card etc. The most of the drives that are used for the purpose of data storage are fragile and the data can be easily corrupted in them. The data storage devices are the ones that are also used for the backup and the archiving of the data. The data storage devices were at a time in the past used to be too costly and expensive. But these days the data storage devices are becoming cheap day by day. Hence the data storage devices price is falling. So, we are in a position to get a storage device for a comparatively cheaper price than the earlier drive. The technology is improving a lot and now the memory storage capacity has gone up TB.
The data in the storage devices can be in the form of the files, databases, digital video and the audio etc. The storage devices that are called as the non volatile can store the data permanently until otherwise erased purposely. This is in the case of the hard disk drives or the floppy disk drives.
The other kinds of the storage media like for example the CD and the DVD can even have again two types of the storage; the first one is that in which the data once written cannot be erased. It is stored permanently over it. While the second type of the CD’s or the DVD’s are called as the rewritable; where in the data that is once written can be erased completely and the same storage device can be used again for storing the different data.

So, we are in a position to get a storage device for a comparatively cheaper price than the earlier drive. The technology is improving a lot and now the memory storage capacity has gone up TB.
The data in the storage devices can be in the form of the files, data bases, digital video and the audio etc. The storage devices that are called as the non volatile can store the data permanently until otherwise erased purposely. This is in the case of the hard disk drives or the floppy disk drives.
The other kinds of the storage media like for example the CD and the DVD can even have again two types of the storage; the first one is that in which the data once written cannot be erased.

Removable Storage Media
The Removable Storage Media are the types of storage devices that are used for the storage of the data. The main reason for using the removable storage media is the ease of portability. That is the ease with which the data can be transferred. The data is of importance and is necessary for the movement in some cases.
Here the case of portability of the storage device comes into the picture. The removable storage media serves the same purpose. More over there are many application of the storage of the data over the removable media. The first and the foremost is the portability that is already discussed above. The next is the issue of the backup and archiving of the data that is important and also sensitive in nature. The backup of data is as important as the storage of data is important.
The CD and the DVD are key players in the removable storage types that are used for the purpose of backup and archiving of the data. The main reason for storing the data over the removable devices is that the data can be easily moved physically from one place to another at the time of any disaster or any other casualty.
The floppy disk drive was the removable storage media that was used for the purpose of storing the data over the disk for the backup. This was the case in the 80’s; but as the pace has increased in the technology the CD’s and the DVD’s had gained momentum for the purpose of providing backup to the data. The floppy disk drives that are available even today do not provide enough memory capacity. And now the concept of the flash memory devices is doing rounds for providing data transfer from place to another.
There are some situations where in the normal data transfer through the networking is not possible. But as in the case of the removal storage media the data transfer can be easily done. Hence the main advantage regarding the removal storage media is the data transfer from the computers to the other computers where there is no existence of the network. The data transfer facility is important even in case; when the network actually exists but there is a failure of the network. In such situations the external data transfer is quite useful.
Also in some cases the data from one system is required to be used through the other system. Here the network connections are not at all possible. Hence the data has to be physically moved from one place to the other. The example for this may be the regular video or the audio. If it is so desired that the video or the audio is to be used through the mode of the large panel television; but the digital video or the audio is in the computer. Hence in such a situation it is not possible to connect the two different types of systems that are the computer and the television. In such a situation the removable data storage devices come into the play.
The solution to this problem is that the digital video or the audio should be burned over the CD or the DVD in the format that is supported by the VCD player associated with the television. And after that is done the video could be used through the television. Similar is the case with the audio also. The removable storage media has one more example of the Zip drives.
non Removable Storage Media
The storage media is generally referred to the secondary memory devices such as the hard disk and the floppy disk drive, CD drive, DVD disk drive, USB drives and the flash memory devices and also to the Zip drives. But apart from the hard disk, none of them are the devices that are non removable in nature. It means that the hard disk is the only mentioned device that is considered as the Non-Removable Storage Media. All the rest are the removable storage media.
Another example that can be used for the Non-Removable Storage Media is the RAM. But it is a volatile memory that cannot be used for permanently storing the data. It is just the primary memory that is of utmost importance to the system but at the same time cannot be used for the backup or the archiving of the data.
The non removable storage media is fixed permanently in to the computer case and can also be used for the backup or the archiving of the data. The hard disk drives are the best suitable example for this type of storage media.
It also important to mention here that the hard disk drive can also either be internal or the external disk drive. In the internal hard disk; the drive is fixed permanently to the computer case. Where as, in the case of the external disk drive the hard drive can be moved from one place to another. Such a drive has a hard casing made over the normal disk drive. It is made to with stand the shocks in case of any physical damage. The external hard disk drive’s case acts as shield and a shock absorber in case of any physical damage. The external hard drive is provided with a USB cable that is plugged into the computer case for the ease of usage. Hence this type of the external hard disk becomes the removal type of data storage. The discussion matters here only with the non removable storage media. Hence the internal hard disks and its types can be discussed elaborately.
The internal hard disk drive is usually fixed in the computer case. The type of hard disk controller gives the name for the different types of the hard disks. The IDE hard disk is the normal hard disk that is used in the regular computers. The IDE controller is used for the purpose of providing connections to this type of the hard disk drive.
The SCSI controllers are used to provide the connections for the SCSI hard disk. The other technology that can be implemented by the internal hard disk drives is the RAID. The RAID is the Redundant Array of Independent (or Inexpensive) disks. In the regular cases the hard disk or mostly the internal hard disk is connected to the motherboard. The motherboard has the IDE connector where in the bus from the hard disk drive is to be plugged in.
If two or more than two hard disk drives are used, then in such case the hard disk drive should clearly be specified as which one is used as the master drive and the other one should also clearly be specified as the slave. The hard disk drive has the jumper settings, by which it can be determined or specified. The internal hard disk is specifically used as the secondary memory. And most importantly the secondary memory that is used in the computer is the non removable storage media. The removal storage media is not used as the secondary memory.
