Pen Drive USB storage and transfer of data, it is simply

Pen Drive is a device for transferring data quickly and with confidentiality. This versatile device that provides high performance and ease of use. Of all these, USB Drive Pen is the most famous and best pen drive.

USB Drive Pen, the name of the device on them because of their size and shape to the user the impression that this is a pen. But in reality this is only the size of a pen and multi-utility device. These pen drives are very light objects. In general, only weighs about 21 grams and comes with internal memory up to 8 GB, which allows it to react very quickly. You can also by a different name, such as flash drives, pen. These units are specially designed without a hat to cover all possibilities of false or misleading. These pen drives are also very popular fashion statement among young people today, because they are usually around the neck to young children, in turn, in a statement of fashion. In addition, this spring discs are available in different colors.

There are also other flash pen drives on the market today, with the internal memory of 4 GB. This Pen Flash Drives are able to give the best results. You can very quickly because it is very little time to store music, video, documents and so on. There are small ways, divisions pen with a built-in 2 GB of memory. These pen drives are very efficient because they are compatible with all types of connected computers and laptops. Although people know that the Drive knob can be any type of data is still on the fundamental values of their size. If a device is small, so that the user data very easily without any problems, which had previously been impossible due to the fact that it is impossible for the user on his laptop and a personal computer to another. Thus, the development of pen drives, things became much easier for users.

There are many manufacturers of pen drives on the market today. Because we know that what is the meaning of pen drives today in people's lives and, therefore, constantly strive to maintain a high quality pen drive customers at affordable prices. Companies, such as a pen Drive, Kingston, San Disk, and many others. USB-pen drive these companies offer high quality at a reasonable price.

Thus, a device that provides a great service at very reasonable prices, but it depends solely on the discretion of the customer that the company Pen Drive is better, and that the capacity of the Organization USB Drive Pen to the needs of clients.

Buy External Hard Drives: How to find an external hard drive

Adding extra storage to your computer, it seems as easy as it seems. However, There are thousands of external hard drive, you and your needs.

Buy an external hard drive in the Apple Store, however, more than just control of the brand, or buy one with the lowest price. There are some important things you need to buy an external hard drive,

Below is a list of what to search for an external drive to get the most out of extra space:

Capacity: To decide on the possibility of an external hard drive that you buy, first, to determine that it is used to drive and additional memory is actually needed. They must use an external hard drive for storing data permanently? Or do you just a temporary backup for file transfer? Permanent storage of data, you can choose high-capacity external drive, 300 GB. Otherwise, simply transfer the files, you may not need much space.

Cache size: the size of the cache refers to the speed of external hard drive to copy files from the source computer. Generally, the larger the cache, or external hard drive, faster than the transfer of files from source to store, and vice versa. If speed is important to you, may also be that a large cache size. However, keep in mind that external hard drives with lots of space for the cache, usually costs more in one Apple Store.

Communications: External hard drives can be connected to a PC or laptop, especially in 2 ways, namely through the USB-connection cable or a FireWire port and cable. While some offer external connections - as well as greater flexibility for users - some come in only one of two options. In this context, is it necessary to use the Firewire connection is faster and faster, the speed of file transfer, assuming that your computer has one port FireWire. Otherwise, go with the USB-port, is compatible with most computers and laptops. For greater flexibility, you can select an external hard drive, which is equipped with two connection options.

Remember that before you buy an external drive to your Mac or PC with an Apple Store, it is always better to know that you need. External hard drives are not always from the manufacturer, brand or price! In most cases, you will need to assess the most important foods, such as capacity, connectivity and size of the cache.

Dual booting Windows and Linux: Single and multiple drives

Internet is full of technical articles, many of them are too complex for the average user who just wants to solve a simple problem. If you know the Internet is also a place where "gurus" a lot of time yelling for help in the discussion boards and forums. So do not feel bad, nobody has the answers to all questions.

Want to dual boot Windows and Linux on one computerit very simple. I only enough space here to say that the most common way to do this in one or more hard disk drives. Clearly, there are many ways to do the job, but there are some basic things you should know. Let's begin with some important information.

Windows and Linux: the same drive
In the operating system Windows, if the master boot record (MBR). Linux, on the other hand do not. In this case, you must first install Windows! After Windows is installed correctly, you can install Linux. This is important! In the Linux boot loader "is called GRUB. LinuxMAKE When installing do not install the boot loader for Linux is in the MBR.

Set boot Windows: in two phases
You can also GRUB to dual boot Windows and Linux on the same block, but it is more complexthe boot into Windows, it will be. The following commands will create a copy of Linux boot sector and then save it in a file on the highest level in a directory of Windows (C:).

Step 1: Linux
From the shell in your Linux installation (boot from the installation CD):
Run the following command, replacing / dev/hda3 with the location of your boot Linux.

Shell # DD if = / dev/hda3 of = / bootsect.lnx BS = 512 count = 1

Copy the new filebootsect.lnxto floppy disk and restart Windows.

Step 2: Windows
Bootsect.lnx copy of C: in Windows. Then run the following command in DOS.

C:> Attrib-H-R-S Boot.ini

Edit Boot.ini to the fact that the first two lines:

[boot loader]
Timeout = 30

After last line add:

C: bootsect.lnx = "Start Linux"

This means that you have done! Restart your computer and you will see a menu that allows you to select either Windows or Linux. Congratulations.

Windows and Linux: Two Disc
It is also very simple. In this case, the device will boot Linux. We will install Windows on a Linux boot loader (eg, GRUB). GRUB is my favorite downloader.

Edit the file / boot / GRUB / grub.conf file. One of the first lines:

Timeout = 30

After last line add:

Title Windows Start
Map (hd1) (hd0)
Map (hd0) (hd1)
rootnoverify (hd1, 0)
makeactive
chainloader +1

Restart the computer with the Linux drive and you will see that the menu you can choose between Linux or Windows. Good job!

This article is, of course, very short and has no explanation of how these work. There are differences, what I have here, depending on the hardware, but I think this is the most common and should work well. I would like to obtain additional resources if it does not work for you.

Against ATA SATA

Hard Disk Drives: compared with the ATA SATA
The results of the computer system was faster processor, memory and video cards are currently being developed. An important component is often ignored, if they focus on improving the performance of a computer system is the hard drive. HDD manufacturers is constantly changing the basic hard drive used in modern computer systems in the past 25 years, and over the past few years there have been some interesting developments, faster, larger caches, better reliability and speed of data transmission.

The disk is used in most computers, is the degree of consumer wealth ATA type drive (usually one IDE disk). ATA standard dates back to 1986 and is based on a 16-bit parallel interface has a lot of changes since its introduction in the speed and size of units that can support it. The final standard ATA-7 (for the first time in 2001, the Technical Committee T13 (a group responsible for the standard ATA)), for data transfer rates up to 133MB/sec. It was expected that last updated the parallel ATA standard.

Already in 2000, it was found that the Parallel ATA standard was up to its limits, that they can. With data transfer rates with the 133MB/sec mark on the parallel cable, you will be invited to all sorts of problems because of signal timing, EMI (electromagnetic interference) and other questions about the integrity of the data, so that the leaders of the industry to meet and develop a new standard, known as Serial ATA (SATA). SATA has been around a few years, but is destined to be "the norm", since a number of advantages, which are used in the Technical Board of Appeal.

Both technologies are: ATA (Advanced Technology Application), 16-bit parallel interface for computer control. Introduced in 1986, has a lot of changes over the past 18 years, with the latter option is the ATA-7. If any question as ATA device as a parallel ATA device. ATA devices, also known as IDE, EIDE, Ultra ATA, Ultra DMA, ATAPI, PATA, etc. (all of these acronyms actually refer to very specific, but they are often used interchangeably) SATA (Serial Advanced Technology Application) 1 - Participation in physical development with the Parallel ATA storage interface.

Key features and links

SATA drives easy to distinguish from their ATA cousins in different data and power connections on the back of the device. A side-by-side comparison of the two interfaces can be found in this PDF from Maxtor, and the following covers many of the differences

ATA-standard, as this model is 200 GB Western Digital, are a bit bulky, two inches wide and 40-pin data cable and 5V to the familiar 4-pin connector. The basic data cables for these drives have been around for many years. This change was the introduction of ATA-5 standard to improve the quality of the signal through a cable 80 in a 40-pin connector (they are usually referred to as 40-pin/80-wire cable). To improve the airflow in the computer system some manufacturers have taken literally folding over the cable, and the inclusion of this position. Another recent physical change also with the advent of rounded cables. The performance of the rounded cables is equal to the apartment, but many prefer the improved air circulation, ease of wire, and cooler appearance that they are.

SATA, as this model is 120 GB Western Digital, have half an inch width 7 "and width of the blade" data connections, resulting in a much thinner and easier to process the data cable. These cables, the convenience of the ATA rounded cables to the next level by using smaller, more flexible and can not, without fear of data loss. SATA cables have a maximum length of 1 meter (39.37 cm), which is significantly higher than the recommended 18-inch cable for ATA drives. Reducing the impact of SATA data space on motherboards, potentially more space for convenience and more functions on board!

A 15-pin connector provides 250mV of necessary power to SATA drives. 15-pin SATA device appears much greater than the power cord 4-pin ATA device, but in reality the two power connectors are nearly the same height. Currently, many SATA drives also equipped with a legacy 4-pin power connector for convenience.

Many modern motherboards, such as a chain of tech motherboard with on board hard disk SATA (many of ATA ports and legacy drive compatibility), and new food sources, such as this Ultra X - a connection, as a rule, some of the necessary 15-pin power connectors, the use of these devices in new systems. Older systems can easily switch from SATA drives using adapters such as PCI-SATA controller and 4-pin 15-pin SATA adapter.

Optical drives are also more easily with SATA connections. Units of measurement, such as the PLEXTOR PX-712SA, to use the new interface, although no more than a comparable optical drives with ATA connection.

Performance

In addition, more convenient to install and drawing less power, SATA performance gains, in fact, that is different from the ATA.

The most interesting feature of SATA power is the greatest possible bandwidth. As we have already determined the evolution of ATA drives, data transfer rate reaches its maximum of 133 MB / sec, where the current SATA standard provides data transfers up to 150 MB / sec. Increase the overall efficiency of ATA SATA can now be expected that up to 5% (by Seagate), but improvements in SATA technology will improve in this regard.

SATA is the future of great things for those who want even greater speed, as well as a device with 300 MB / s transfer rate (SATA II) in 2005 and 2008 at speeds up to 600 MB / sec can be expected. These incredible speed and it is difficult to predict at this time.

Another advantage of the performance of SATA drives is built-in hot swap capabilities. SATA and offline, without a break in the system, for those who can not afford the time and you want to move in and out of operation quickly. The largest number of wires in the power supply part of the same, while six out of fifteen for the cable, the hot swap function.

Price
Comparison of ATA to the SATA can be tricky, since all the variables, but, as the case that SATA drives will still cost only slightly more than in the ATA-compatible disks. The gap quickly, but as SATA drives gain popularity and availability of price changes can be expected. Taking into account the advantages of SATA over ATA, the potential difference of a few dollars can be justified when you upgrade. Geeks group currently has only a limited selection of disks SATA, but several technical sites, such as equipment and technology room, we present a real-time prices, to see how comparable units.

Final words
The current SATA standard provides significant benefits in the ATA in terms of comfort, and especially energy efficiency. Main ATA is on their side this time is history, as it is the norm for so long that they do not disappear in the near future. The future of SATA will be even more interesting to increase the speed of the hard drive to develop along with other system components.
