The second video card made ??by Nvidia situated at the high-end level after GTX 580 is GTX 570 which is actually a version of the GTX 480 to which was added the true video chipset GF110. It is not easy to build a 3 billion transistor GPU on a 40nm fabrication process, Nvidia doing this the hard way with the GTX 480, GTX 470 and GTX 465, managing a balance between performance, noise and the heat released only with the GTX 470.

The package of NVIDIA GTX 570 contains:
-2 connectors adapters Molex to 6 pins
-1 DVI-VGA adapter
-Technical books plus DVD drivers
-Mini-HDMI cable to HDMI adapter

In terms of connectivity, Nvidia has used two dual-links DVI and a mini-HDMI, so it is not possible to connect three monitors to a single video card and if you want it you must choose SLI solutions. Since the GTX 570 has a lower TDP than 580 (219 W compared with 244 W), Nvidia is cutting the 2 auxiliary power pins. As I said, GTX 570 comes with 1.2GB of memory. The reference models are set at a frequency of 732 MHz core, 1464 MHz on shader processors and GDDR5 memory running at 950 MHz’s.

GeForce GTX 570 has a maximum power consumption of only 219W, as such; you will need a power supply 550-600W minimum two 6-pin PCIe. As with any high- end video card, Nvidia offers the multi GPU option for linking in SLI up to 3 video cards of this kind. The heat produced by the video card is discharged through specially designed slots under the connectors. Always make sure there is enough airflow in the case to ensure optimal operating temperature.

A storage unit is a device that is used to store computer data. Computer users can now choose from a variety of storage devices. Each drive has its own advantages and disadvantages. Technology has advanced greatly, and now companies come up with ingenious solutions to align with your needs in terms of storage units. Therefore, below you will find a detailed description of an elegant storage solution- the Wireless HDD.

Surely, you've always wanted a computer that does not have dozens of wires. At the desktop they may not be so annoying because, being in the back side, the wires are not visible. But the situation is dramatic when it comes to laptops. But there is a more elegant storage solution, so that you can get rid of wires and you also enjoy some additional advantages: the wireless storage unit. There are many such devices on the market. In fact, they are not only HDD wireless, but wireless routers with built-in HDD. So it give us the functions of a wireless router (802.11b/g/n, 4 LAN ports, control of security, online management system, etc.), plus some ways of storage and other specific applications.

Why would we want such a device in our house? there are several reasons for this. First of all, it can be used as a shared storage unit. If you have multiple laptops in the house and you want all of them to have direct access to your collection of movies, for instance, you can store the collection on your wireless HDD and each laptop can use it. Simple, easy and convenient. To that it can be used as a torrents manager. You will no longer have to leave your computer turned on to make ratio on torrent sites. In addition, those who have laptops with HDD with only 5400 rpm, you know what effect the torrents have on the performances of the laptop: it is starting to run slowly. With this device you get rid of both problems and this because the HDD from interior can be replaced easily with a better or larger storage capacity. Because it offers the functions of a wireless router. Because it's a device that eliminates the many cables and combines the functions of two different gadgets into one. So, there are a lot of reasons why we should love these toys.

There are also negative aspects, the main ones being:
-Low transfer speed of data through wireless. The 802.11g standard is allowing a maximum speed of 54 Mbps, while USB 2.0 has a theoretical top speed of 480 Mbps. In reality, the speeds are much lower; the rate of transfer of 2-3 MB / s being pertinent for this device, through wireless.
-The price is one negative aspect that can’t be neglected. One such device can cost about 295 dollars. All in all, these solutions are very interesting and useful. We have said what are the advantages and disadvantages of this device; if you buy it or not it is up to you. In my opinion, this is a device that is worth investing the money.

It is not a secret that computer manufacturers are constantly looking to improve hardware components and to come up with innovative models and a higher performance. Therefore, we are all anxiously looking towards the technology of the future. However, hard drives are a specific aspect that concerns us even more.

This because they are the only mechanical items from a computer, excepting the optical drives - that are not crucial for the overall capacities. We are probably hoping for a mind - blowing technology. Nevertheless, are we really going to get one?

Streaming Video
If you cannot picture the way that a streaming video would interfere with a hard drive, wait and see. The drives would be optimized in order to work at their very best quality together with a video streaming, the random access that we nowadays use being replaced. The first positive results would be a considerable decrease of the error checking processes and a significant improvement of the reading and writing speed of the hard drive.

More storage
More storage is something we all gladly accept, no matter how much we already have. One possibility is about perpendicular recording. The present technology is based on magnetic bits that are lie flat. Making the bits to “stand up”, they will occupy a smaller surface on the disk, allowing a larger storage capacity. Another possible adjustment will imply using a laser beam to warm up the magnetic bits soon before they are about to be written – this makes them more stable and reliable for holding data. Nevertheless, consumers seem to be looking for more generous storage rooms but for smaller drives in the same time, which will not seem to be a problem.

Solid State Drives
Solid State Drives are shortly known as SSDs. Their main characteristic is that they use a non – volatile memory for storage. The procedure is similar with the one of USB flash drives. SSDs access information without moving parts of the stored data, making you to suddenly benefit from an increased performance. The operations will be done in a shorter time, with fewer failures. Good – bye mechanical parts, good – bye drive crashes. With no physical pieces in movement, there is nothing to go wrong with your hard drive. If you have little knowledge about the volatile memory, you are probably already asking yourself how will the data be kept on this support. Volatile means that once you turn off the computer, it goes away. Only that your new hard drive will have a battery, so it will be supplied with power even when your computer is not working. Problem solved.

New grains
Grains are the little magnetic cells, of no more than 10 nm in size, forming the magnetic field of any hard drive that we currently use. A single bit can be made by up to 100 pieces of cobalt – platinum grains.

The computer hardware of each PC represents the collection of components which can be touched. These are the main components which are located inside the computer case and all of them work together in order to make the computer run properly. The computer software on the other hand, represents the total of computer programs which are to be installed on the computer. The hardware will function properly only if the proper software is installed on the computer. As you can imagine, the software can not be touched, as it is only computer data.



There are different components which form the computer hardware and in what follows I am going to present them to you. It is only suitable to start with the beginning and that should be the motherboard. The motherboard is the component on which all the other components connect. In order to make the connection between all the components, the motherboard uses different integrated circuits. It is important to know that certain components are only compatible with certain motherboards, and in many cases a change of the components might require a change of the motherboard as well.



One of the most important components which connects to the motherboard is the “brain of the computer”, which is the processor. It can also be called the CPU or the central processing unit. This component makes all the proper calculations which assure that the computer works in a proper manner. The processor communicates with all the other components as well and that is done through the chipset. The CPU connects to the chipset which then connects to the motherboard.



Another important component of each computer is the memory. The RAM or Random Access Memory will store all the data which is provided by the processor, motherboard, video card, and so on. This data is lost as soon as the computer is reset. It is advisable to have as much memory on the computer as possible because the more RAM you have the more data it will be able to store and the better the computer will work.

The video card is an important component as well because it creates the output for the computer monitor. Every computer has a video card, whether an integrated one which is included in the motherboard, or an external one which connects to the motherboard. The external ones are able to produce a much better performance than the integrated ones and because of this they are suitable mostly for gaming computers. The hard drive is the component which stores all the computer data, which is somewhat similar to the RAM, the difference being that the data is kept even after the computer is reset.

In this article I am going to talk about the computer storage external hard drives. As it is natural, I am going to start with the beginning. The computer storage refers to various computer devices, components, and recording media which are used in order to retain digital data. The computer storage device is one of the most important components of a computer. The original computer contained only the hard drive or the CPU, or the processor. The external hard drive is a type of computer storage devices such as a hard disk, but which is external meaning that it is connected to the computer by an USB cable in most of the cases.

There are many types of external hard drives, each having various interfaces such as SATA, IDE, FireWire, USB, and so on. There are many things you need to take in consideration before deciding to buy the external hard drive. First of all you should know what type of data you would like to store on it. If you would like to store movies or games then you should opt for buying a larger hard drive which would be able to store large amounts of data. On the other hand if you would like to store only photos or documents, buying a very large external hard drive would be a bad choice.

The brand can be very important just like in the case of other devices and machines. It is not always advisable to buy depending on the brand but sometimes it is worth it. There are many brands which are specialized in this domain, and as you can imagine, the hard drives offered by these brands are better than the ones of an unknown brand. If you like a certain brand, and if you know that their products are great, then you should go with it.

Once you have identified the hard drive that you want to purchase you should look for the best price offer for it. Visit various stores or browse various websites that sell the model that you wish to buy. There is no reason to pay extra money for the same products just because you did not want to waste some time. Always read reviews for the products that you intend to buy. If the reviews are mainly positive then you should not worry when it comes to buying the product. On the other hand, a product which has received mainly negative reviews it will most likely be bad. I would not advise you to buy such a product which has received negative reviews, but it is your choice. These are just some of the facts about the computer storage external hard drives.
