How a hard drive Works

The hard drive is connected to a series of magnetized discs with a spindle. The spindle rotates the disk at a very rapid pace, while a number of read / write heads scan both looking for information and writing. This information is used by a cable system or via a wireless connection to a hard disk controller to transfer in most systems on the motherboard or in some systems built and installed as an add-in card. The information comes from your hard drive through its controller is then placed at the disposal of computer components. The effectiveness of your hard drive (performance) will depend on how much of its capacity is unused, how well organized the data (known as fragmentation) and its transmission rate, which in turn depends on its type and connection speed of rotation of the drive.

Hard Drives

Most computers of most models of home base to the power of the servers have an internal hard drive installed. Today’s technology ensures that all are generally fast, reliable and offer storage capacity reliable. Most modern computers have installation slots and cabling to install additional hard drive. So you can your storage capacity without increasing your existing hard drive.

External Hard Drives

These drives are installed in essentially the same as those drives in computers, but in a pouch, carrying case. This is a good solution for people who work remotely and need to transport large quantities of data. When an external hard drive of your choice will ensure your computer is compatible with the interface that the hard drive used. An expansion card, such as a FireWire card can help enhance the capabilities of your computer. You can compare different brands of external hard drives Myshopping too easy. com. AU to seek the connection type, or other specifications.

Notebook Hard Drives

There have been many advances in the miniaturization of hardware components for laptop computers and hard disk technology has been out of the loop on the left. Laptop hard drives function in exactly the same way as internal hard drives and other computers, but they are designed to provide storage and maximum efficiency in the smallest package. Eligible for even more flexibility, some laptop computers with removable hard disks, which can be easily installed and removed. But before buying a hard drive of your laptop, make sure the hard disk specifications will meet the standards of the computer, as many portable hard drives are copyrighted and may not be compatible with other brands and models.

Size

The hard drive stores your operating system, programs (games and applications) to work your data and your digital music and movies. Most new computers bought at least 80 GB of hard drive space, many more. Disk space is one of those things when you’re there, you find ways to meet you soon enough. There is no real rule of thumb to consider, but the cost per gigabyte of storage as a way to make your purchase. When you work with large files such as music, videos and graphics, it pays to have a large storage space for your work. You may pay two hard drives, have a house that all your programs and applications, and another for storing your work and projects.

You can compare prices, say, a hard disk of 160 GB with two 80 GB disks. If one drive fails, all is not lost. Hard drives today, however, are very robust and they do not abuse the equipment you use for a longer period.

Interface

A key differentiator between hard drives, it’s how they connect to your computer. There are a number of basic types of connection schemes used with hard drives. Each connection has a number of differences in performance.

IDE (Integrated Drive Electronics)

These connection methods the most common. As the disk controller on the drive itself, rather than on the motherboard, it helps to keep costs down. There different IDE standards available. In most cases you want to be able to buy the fastest computer can support standard. On most computers, a standard that is faster than the computer currently supports, so that you can buy a medium faster hard drive, and update your computer at a later date. Different EDI standards to base for more rapid are:

ATA (Basic). Supports up to two hard drives and has a 16-bit interface, handling transfer speeds up to 8 3 MB per second.

ATA-2 or EIDE (Enhanced IDE). Supports transfer rates up to 13 3 MB per second.

ATA-3. A minor upgrade to ATA-2 and offers transfer speeds up to 16 6 MB per second.

Ultra ATA (Ultra DMA ATA-33 or DMA-33). Significant improvements in speed, with transfer rates up to 33 MB per second.

ATA-66. A version of ATA that doubles transfer rates up to 66 MB per second.

ATA-100. An upgrade to the ATA standard supports data rates up to 100 MB per second.

ATA-133. Mainly in systems based on AMD (not supported by Intel), with transfer rates up to 133 MB per second.

IDE / EIDE Hard Drives

Serial ATA Hard Drives

Ultra DMA 100 hard drives

SCSI (Small Computer System Interface)

This is the hard disk interface is used by many high-end PCs are used, networks and servers, and Apple Macintosh computers, except the Mac first and latest iMacs. While some systems support SCSI controllers on their motherboards, most with a SCSI controller add-in card. SCSI drives are generally faster and more reliable, and the SCSI interface allows you to connect more than IDE drives. While SCSI drives in various standards, including a large number of them are mutually incompatible. Therefore, it is important to know that your computer is the drive you want to install support. The different SCSI connections are:

SCSI-1. A simple connection to a 25-pin connector and supports data rates up to 4 MB per second.

SCSI-2. Uses a 50 pin connector and supports multiple devices with a transfer rate of 4MB per second.

Wide SCSI. These units have a wider cable and a 68-pin connection that supports data transfer 16-bit.

Fast SCSI. Uses an 8-bit bus but transfers data at 10MB per second.

Fast Wide SCSI. ) Double or by bus (16 bits) and the transmission rate (20MB per second.

Ultra SCSI or Ultra Wide SCSI. Uses an 8-bit bus and transfers data at 20MB per second.

SCSI-3. Has a 16-bit bus and transfers data at 40MB per second.

Ultra2 SCSI. Uses an 8-bit bus and transfers data at speeds of 40 megabytes per second.

Ultra2 Wide SCSI. Uses a 16-bit bus and supports data rates of 80MB per second.

FIREWIRE (IEEE 1394)

FireWire is popular in portable hard drives because it can be connected and removed without restarting the computer. It supports data rates of 50MB per second, which means it suitable for video, audio and multimedia applications. FireWire requires a dedicated add-in card and hard drive in an external power source required, but the interface supports up to 63 devices simultaneously.

FireWire Hard Drives

USB 1 1 (Universal Serial Bus)

Virtually all computers today have USB ports on their motherboards. (On older models, you install an expansion card.) USB controller can be used to connect external hard drives and can support up to 127 devices simultaneously either port USB hubs or a related way garland. USB controller is also part of the power supply for connected devices, but many hard drives still use an external power source. USB is characterized by its speed of data transmission, while the maximum of over 1. 5 MB per second.

USB Hard Drives

USB-2. 0 (Hi-Speed USB)

A study recently put in place, and far better connection standard for backward compatibility and rate of data transfer up to 60MB per second. Can use USB 1-1 System, a USB-2. 0-unit requires a USB-2. 0-control board to achieve data rates higher.

USB-2. Disk 0

Fiber Channel

The fiber cable is used mainly for servers broadband network and workstations, offering fares very fast data transfer (up to 106MB per second), and the wired connection to long distances, but it is expensive and you need a special interface card. reinstall

Rotational Speed

Rate of data transfer is crucial to how your computer performs for you. Besides the above types of connections, the performance of your hard drive depends on the speed measured in RPM. RPM usually means higher faster data transfer rates. The lowest speed spin in the calculation is now acceptable at 5400 rpm. The common standard is now 7200 rpm. But higher speeds are SCSI drives available, and it is an area of technology computer system that is constantly being developed.

3600 RPM hard drives

4200 RPM hard drives

5400 rpm Hard Drives

7200 rpm Hard Drives

10000 RPM Hard Drives

15000 RPM Hard Drives

A larger hard drive capacity will not necessarily make your system work faster if you run out of disk space with your existing drive. But with an Ultra ATA/100 hard drive or ATA/133 and 7200 rpm, a speed of rotation will be pretty hard offer improved performance.

Other considerations

CACHE

Cache (pronounced “cash”) is an additional temporary memory that acts as a buffer between the system and the reader. Frequently accessed data is stored in the cache for quick access. Cache sizes range from 512 KB to 16 MB on some SCSI drives. The larger cache you have on your hard drive, more disk, the data transfer. Do you work with large files such as videos, images and audio files, it is the largest cache you can have contacts (8 MB or more).

Seek Time

The data on your hard disk are stored in tracks and sectors, and if you entrust your hard disk controller to retrieve data, it fetches. The search time is a measure of how long it takes to find the hard drive on a track on a disc. Search time can be anything from the hard disk to the hard disk drive with a faster each time always looking for better performance.

Internal transfer prices and external

These two rates tell how fast a drive actually reads data and transmits to the system. Internal Transfer Rate refers to the time it takes for a head-disk drives to read data from disk and it goes into the disk cache. External Transfer Rate (and sometimes the rate of data transmission rate or the burst transfer) is a measure of the time it takes to send data from the cache, all the way into the computer memory. Of course, transfer rates faster to provide better performance.

SMART (Self-Monitoring Analysis and Reporting Technology)

This is a nice built-in function in some disk drives that help you have a problem of hardware Can. The BIOS of your computer must support them so that the SMART function it to work, but the disk itself is still in a system without working.

If you have never bought an external hard drive before then, there are a few tips that have on your shopping list before going to help May the final purchase decision. 1. Buy a brand do yourself a favor and buy a brand that you recognize easily. Sure, it costs a little more x-mark is, but with accessories, as you do this really what you paid. If a cost Maxtor 100GB external hard drive $ 200 and another mark x 100GB hard drive costs $ 80, why do you think that? As the company you love? Because they do, how to obtain smaller gains? No, because it is a cheaper player with inferior parts that will break much sooner than you think to do. The other aspect of joining a brand is your guarantee. For example, Maxtor, Western Digital and Iomega and reliable companies are known for their external hard drives. If something goes wrong with your drive, you can find out. With Brand X, you probably will not be able to e-mail that you can find contact information for parents. Saving a few dollars worth risk? 2. When it comes to connectivity, external hard drives, you must choose carefully selecting your connection type. Your external hard drive or via USB or Firewire support. FireWire is the fastest option available at the moment but your computer can not support it. The vast majority of modern computers, however, with a USB port. The next question is: what kind of connection USB – 1st have 0 or 2 0? If your computer has only a USB-1. 0-connection and the external hard drive to transfer data very slowly. USB-2. 0, the minimum, you should consider when connectivity to your computer and your account external hard drive. If you do not have a USB-2. 0-port (also Cal

3. Google it What is the make or model you choose, make sure you do some research before buying. Still, Google still had the brand and exact model of drive you are considering. Based on the above comments and feedback on the reliability of a disk. You will be surprised that some companies have a particularly bad reputation for the reliability of the system and what is “click of death” known in the industry external hard drive. Spend time in Google to check your potential purchase. You not regret it. leading Hi-Speed USB) on your computer, you may need a USB-2. 0-card equipped.

4. Now, of course, speed, we need to talk about speed. More hard drive is working, the speed of data transfer to your computer and vice versa preserved. Without you with jargon comptuer surprisingly, there are some technical things that you include on your shopping list. Search time -) to be 10 ms (milliseconds or less the buffer size – more is better. Get a disk with 4 MB buffer. RPMs – the highest possible. 5400 rpm minimum. 7200 rpm, are preferred. Follow the basic instructions above and you are exactly right. 5. This size is the easy part of the whole “buying an external hard drive” equation. So, buy what you can pay . If you get 100GB. However, if you can afford 200GB then search. And then, if you’ve amassed a few dollars more you could afford 300GB then you do. This is not an argument sale. Far from it. There is simply no such thing as too much data storage space. Filled with a hard disk of 160 GB that I’m here until a little less of one month. Currently, an option terabye sounds good to my future needs. Add more than 50% on your needs for data storage. Honest. They are themselves in the first 90 days of purchase of your external hard drive. We hope you’ll be better prepared for the purchase of your new external hard disk drive. It is one of the best purchases you ever made.

So you’ve finally decided to buy an external hard drive as a backup option for your computer. This is a good choice for you because you save your data to make it faster and easier than you ever imagined. They are also your data much more portable in larger quantities than before. They are saving a few hundred megabytes, or even multi-gigabyte limit. No. Now you can expect a portable storage capacity and reliable terabytes. It’s frustrating computer or use file system backup server even easier by far.

A Universal Serial Bus or USB is a serial bus device which is used to interface various electronic gadgets. A USB devices such as shippers, and allows printers to be connected to devices through a single standardized interface socket. This helps to improve the capacity Plug and Play devices as they can be easily connected and disconnected without rebooting the gadgets. A USB power supply also features low power consumption. USBs were originally intended to be used on personal computers. But thanks to advances in technology, these devices are now widely used in devices such as personal digital assistants (PDAs) and video game consoles. A USB has become a standard connection method for most of these devices. Several variants of USB drives are available in markets. These variants have been developed for specific use on various electronic devices. This variant is a 500GB USB hard drive. A USB provides links to various storage devices using a set of standards called Standards of Class USB Mass Storage Device. 500 GB USB hard drive can store up to 500 GB of electronic data about them. A USB is not acting primarily as a bus to the memory of a computer. This work is best done with buses like SCSI and ATA. A number of manufacturers offer high performance external USB hard drives for consumers these days. These external drives usually contain a device that is the translation of readers of conventional technology with USB interfaces. A USB supports three data rates – Low-speed (187 Kbps), full speed (1. 5 MB / sec) and high speed (60 Mbps). Researchers working on a USB key that data at a speed “Super” transmission (600 Mb / s is). A 500 MB USB disk must be disseminated widely used in many modern computers. Technological advances have made possible the market for these devices at lower prices.
