Storage Devices, News

For many years the development of storage devices is constantly improving its quality.

The market is in constant competition, as well as all companies are always trying to take the lead. Using the CD-ROM, in 1979 and replaced the floppy disk format. The most common form of CD-ROM can 80minutes/700 MB.

Then the DVD format is very popular, it can store much more data, often a layer DVD can hold 4.7 GB of dual-level, and 17 GB dual layer DVD can be.
Another mechanism is very useful, USB Drive Pen, which is now largely in the world. This type of device has a storage capacity varies, USB pen drive can store up to 16 GB, but there are also some that can store 128 GB. In the Pen Drive can be found with many forms and colors that are less burdensome than the CD and run faster in the process of data transmission.
Latest news on the storage devices is the creation of a new type of DVD, DVD High Definition (HD DVD), but primarily through its direct competitor, Blu-Ray or BD.

These two new formats to improve the quality of audio and video are more detailed and for the public to live a realistic experience.
BD high capacity. With the blue laser is able to store up to 54 GB of data, almost 12 times more than the simple single-layer disc. This potential is enormous, but the drives are used in MPEG-2 video producers tend to restrict themselves for about two hours of high definition content of one layer BD-ROM. This requires the creation of two discs (50 GB), as well as new advanced codecs such as MPEG-4.

In July 2008, also announced that the 16-layer 400GB Blu-Ray, but not yet commercialized.
Today there is no doubt that the battle was won BD, and in February 2008, Toshiba, who owns the rights to the rival format, announced that they no longer develop, manufacture, or market HD DVD players and recorders in force until the format war.
Sony PlayStation 3 has proved a catalyst for Blu-Ray discs, PlayStation 3 uses Blu-Ray disc as the primary means of information storage, without the console, users must have a BD-player, as well as, perhaps, a new kind of TV screen with high resolution for these types of disks.
This is certainly an obstacle to the mass dissemination of this technology, at least in the beginning of the year.
Although each film production company has already announced its support for the format of BD, and has already begun, the release of the film in this format.

The big question is whether this format will be able to save the low production costs, but low prices for consumers.
So far, it seems that CDs cost more or less the same as a normal DVD. The real problem is that sales of BD players are much less than expected. This is because consumers believe that the DVD quality is quite good, often at the cost of BD players are still too high, and consumers are not in the vast majority see improvements in the quality of audio or video for the purchase of this new device. And still no one can say that they are wrong.
