Choosing The Best Hard Drive

September 11th, 2011

Choosing The Best Hard DriveAlmost all personal computers today contain hard drives, generally with many gigabytes of storage space. Hard drives are able to store a lot of information permanently using electromagnetic surfaces to record digital data. You can write on them and rewrite on them, which is what makes them so versatile in computers. It holds records of characters in text files, pixel coloring in images, and executable programs for software. It’s what makes storing programs, music, photos, and other items possible. There are many different kinds of hard drives available, and it can be difficult to choose between them all. Here’s a breakdown of the different aspects that you should consider.

Storage space

These days, you can get a reasonably inexpensive hard drive with about 250GB, which is plenty for most people. However, paying a bit more can get you a lot more space. It depends on your needs. If you plan to install many large programs, or have large music or video collections, think about getting a hard drive with more space. You can also compare cost per gigabyte for various sizes. You’ll find that you usually pay less per gigabyte if you get a hard drive with more storage space. You don’t want to end up getting a hard drive with limited space if you plan to use it up quickly. It’s more efficient to spend a little more initially, so you don’t have to go to the trouble of upgrading later.

Motherboard specification

There are a few different types motherboard controllers that you’ll find in the standard personal computer. These give you the ability to connect your motherboard to various types of storage devices, including hard drives. Serial ATA (SATA) and Parallel ATA (PATA) interfaces are the two main types. You can look for information about connection capability in your computer manual, or by physically checking for the ports. Motherboards with SATA connections use a hard drive with SATA specifications. Likewise, those with PATA connections require a PATA hard drive. Sometimes, you’ll find that the motherboard supports both forms. In that case, you can use either a SATA or PATA hard drive, although most people choose SATA, as they tend to be less expensive and access data more quickly.

Performance

Rotations per minute (rpm) influence a hard drive’s performance, i.e. how fast the hard drive can read or write digital information. A hard drive with a higher rpm will perform better. Most old computers will be fitted with PATA hard drives, while newer ones tend to use SATA. A SATA hard drive is slightly better performance-wise, being about 5% faster than PATA. There are also SATA2 hard drives, which perform operations even faster. However, these are usually unnecessary unless you are using a demanding program like a graphic-intensive video game. If you plan to go with a SATA2 hard drive, you’ll probably have to also get new components for your computer so the format is supported. As you’d expect, the faster models are more expensive. The common SATA interface is acceptable for most computer processes.

Physical size

You’ll find several different sizes of hard drives available. 5.25” hard drives were the standard in the past. Today, most computers accept 3.5” hard drives, and notebooks have 2.5” hard drives. If you have an old computer with a 5.25” bay, you can fit a smaller hard drive using special rails. In terms of cable size, the old PATA hard drive connector cables take up more space, as they’re thicker. SATA hard drive cables are narrower, and easier to connect.

Noise level

In general, the faster the rotation speed of the hard drive, the louder it will be. Larger hard disks also tend to be noisier. All hard drives make noises, although different brands have various methods to reduce these sounds. As a result, you’ll find that some hard drives are quieter than others. You should look for notes about how it is designed to reduce these noises when you’re searching for a new hard drive. If you’d find a noisy hard drive annoying, it’s probably worth paying a little more to get a quieter one.

Warranties

Manufacturers often offer warranty periods for their products if sold by authorized businesses. It’s up to you whether you believe extra insurance is worth the extra cost. If you’re buying a hard drive from a discount store, it’s probably more important to get a warranty. If a hard drive crashes, chances are you won’t get your data back anyway. The best insurance is to back up everything on it regularly.

Thinking about these elements of hard drives can help you find the best hard drive for your purposes. Some people are happy with inexpensive small and relatively slow hard drives. Others need more space or faster processing speeds. Choosing the right hard drive for you can seem daunting, but with a little research you can get the best one for the least amount of money.

Advances In Display Screen Technology

August 2nd, 2011

Advances In Display Screen TechnologyDisplay screens are a relatively new invention, with new technologies emerging all the time. The television offered one of the first widely used display screens. With the invention of the cathode ray tube, it was possible to create moving images in black and white. In time, they developed color television, movie screens, computer monitors, and many other display screens. Today, these technologies are being developed at an unprecedented rate, and sold worldwide on a large scale. We now see new kinds of screens being developed which allow for novel product designs. Here are the descriptions of some of the common display screen technologies used currently.

Light-emitting Diode (LED) Display

A light-emitting diode is a type of light source produced by encouraging electrons to release controlled energy in the form of photons. These tiny lights are arranged into LED panels, which can act as a small display screen or as a component of a larger display. Red, green, and blue diodes are arranged in clusters to produce color images. LED displays are commonly used outdoors. They are often used on store signs or billboards, for example. Indoor LED screen technology is slightly different. The diodes are set very close together, and mounted on a board, reducing the maximum viewing distance.

Organic LED Display (OLED)

OLED technology follows the same general principles as the LED displays. However, the luminescent layer is comprised of organic compounds, which are electrified to produce light. This technology works well in computer monitors, television screens, cell phones, and watches. The OLED is able to function without a backlight, unlike the traditional LED displays. This means that that OLEDs are able to display dark colors better. Also, since there are fewer components, the physical screens can be less bulky. One drawback of this technology is that it is particular susceptible to water damage. The biggest issue is that of the lifetime of the organic components. These screens have color fading faster than other designs due to this degradation.

Liquid Crystal Display (LCD)

LCDs work by utilizing electric fields to manipulate liquid crystals within these screens. The orientation of these crystal molecules changes the way light moves through them. This property is harnessed to develop images. This technology is far ranging, found in everything from televisions and computers to digital clocks and calculators. It is popular because it allows screens to be thinner and more energy-efficient than some other technologies.

Plasma Display Panel (PDP)

This technology is commonly seen in flat screen televisions. The image is created when gases trapped between glass plates are excited with electricity. The gas turns to plasma and emits ultraviolet light, which in turn excites phosphors to emit the colors that you see. It is able to create high quality pictures with good color reproduction. Plasma screens are also able to handle video displays with a lot of fast action, since they have a high refresh rate. The more power the screen draws, the brighter it will be. However, older models are susceptible to becoming duller as they age, although newer ones have mainly corrected this problem.

Video projector

A typical video projector displays a video signal input on a screen using lenses and lights. Modern projectors are able to improve the displayed image with manual settings that eliminate blurriness and inconsistencies. Video projectors are very useful in a classroom setting as they make material large enough for the entire class to view easily. They’re also commonly used in other types of presentations, and within home theater systems. Cathode ray tube systems utilize red, green, and blue tubes to produce the image. Other projectors use LCD lights, which allow for a less expensive system. LED projectors are similar, but they use light-emitting diodes.

Touch screen

A touch screen is an electronic display that can be manipulated through pressure by using a finger or other object. This technology eliminates the need to use a mouse or touch pad to interact with the displayed information. More and more, it is being integrated into PDAs, cell phones, video games and computers. A common way to design touch screens is by using resistive information. The outermost layer is made of polyester with a metallic coating on the bottom. Next, there is an adhesive spacer. The third layer contains another conductive metal coating. When someone touches the screen, there is electrical activity between the metal coatings. These changes are then recorded by the system, and used as the basis for programming the interaction.

Electronic paper

E-paper or electronic paper is designed to mimic real ink and paper. It does not illuminate pixels from the back, and is able to display images for a long period of time without requiring electricity. There are several different technologies that contribute to electronic paper design. Electrophoretic displays create images by manipulating particles with electric fields. In an extension of that, electrowetting applies voltage to an oil/water interface to produce a display. There are endless possible uses for this technology. It can be used to read books and newspapers, and may even replace paper in schools eventually.
