Hard Drives- Choosing the Right One

Hard drives come in many different sizes and configurations. How much data a hard drive can hold is measured in gigabytes (GB). The latest hard drives can hold anywhere from 80 GB to 1000 GB (1 TB)! When buying a hard drive, size isn't the only factor to look at, however. By choosing the right hard drive for your needs, you'll enjoy your computer more. Hard drives are inexpensive and you should never skimp on one to save money. For business or basic home use, an 80 GB hard drive should suffice. If you plan on downloading music, movies, or installing a lot of games on your computer, your hard drive should be at least 160 GB. For laptop users, the same space requirements apply, however, many laptops come with small hard drives. Many laptop users choose to keep the small hard drive and buy an external hard drive for excess files to keep costs down. You can have a huge hard drive, but it will be worthless if it doesn't move data fast enough for your computer! To find data, hard drives have platters on spindles that spin, similar to a CD. How fast a hard drive spins is measured in RPM (revolutions per minute). The higher a hard drive's RPM is, the faster it will perform. Desktop hard drives almost always have 7200 RPM hard drives. Laptop hard drives can range from 4200 RPM to 5400 RPM for budget and midrange uses and 7200 RPM for high end use. Hard drives with RPMs of 10,000 or more are available, but those are mainly for gamers, computer enthusiasts, and servers. If you are computer user looking for performance, you should know about RAID. RAID lets you put 2 or more hard drives of the same brand and model together and run them at once, which results in faster performance. You can also use RAID so the second hard drives automatically backs up data from the first hard drive, so you always have a backup of your data. There are numerous possible RAID configurations out there, too many to mention in this article. A hard drive's cache is also another important performance indicator. A hard drive's cache will hold frequently accessed data for faster access by the computer. A good hard drive will have at least 8 MB of cache. As with RPM, the more cache a hard drive has, the better. Hard drives generally have either an SATA or IDE connection. Both connections are for attaching the hard drive to the motherboard via a cable so that data can be sent and received to and from the computer and drive. SATA is the newest connection and is better than IDE in that it can be faster and uses a much smaller cable. IDE, however, is just as fast as IDE in real world performance testa and hard drives that use IDE are cheaper than SATA hard drives. However, IDE hard drives use large cables that can restrict airflow. Fortunately, you can buy a rounded IDE cable that is not as big for $5-$10 at almost any computer supply store or online computer part retailer, such as Newegg.com or Fry's Electronics.

The Urge To Download

If you've been hearing the buzz on Urge recently, it's not about a deep desire or compulsion - it's about MTV's offering to the world of online music downloads and streaming. Urge is a subscription based music download service in which its patrons can subscribe for a monthly fee of $10 and listen to as many of the 2 million songs in MTV's coffers as they like. If they'd like to download that song, then it costs 99 cents each. But it's not just MTV behind the latest addition to the world of online music. Microsoft and MTV are working together on this one. Bill Gates must have seen the success of similar sites like Napster and Rhapsody and decided to jump on the bandwagon. Urge's challenge will be to convince all those music lovers who prefer to buy songs and download them through sites like the incredibly popular iTunes, owned by Apple computers, that subscribing to a site and being able to listen to whatever songs you like, in whatever order and as often as you like is just as good or better than buying them one by one. It's just one more battle to add to the long running conflict between Microsoft and Apple. Does Bill have anything different to offer through Urge? Anything that makes this latest venture stand out from similar sites? Not really. Should you choose to become an Urge subscriber, you won't find any music that you wouldn't find on any other download - subscription site. The prices are even pretty much the same. What they do offer is a aesthetics - their site looks good. Plus, there's the camaraderie. Subscribers can post on blogs and converse with one another. But that's about it. But with Microsoft powering the marketing and advertising engine behind Urge, it's sure to do well. Even the latest incarnation of Microsoft's Windows Media Player has Urge built in. Everyone with a PC has access to this free player and therefore easy access to Urge. What PC users won't have is the portability provided by the wildly popular iPod. Current owners of iPods, should they decide to subscribe to Urge, will have to buy songs through the site, download them, burn them onto CDs and then convert the music files to mp3s in order to be compatible. Other portable devices are compatible with the service, however, and those are listed on the site. This all may change in the Christmas of 2006, as buzz indicates Microsoft plans to release their "iPod Killer". Based on the Xbox brand, and including additional features like gaming, this media player is aimed right at Apple's heart, and could quickly make "Urge" a household name, assuming the two products are closely linked. Each of the music download sites has their own strengths and weaknesses. Urge fully divides and subdivides genres so that its subscribers can easily find what they're looking for while exploring other bands that they might like. Yahoo Music Unlimited personalizes the start page to include suggestions based on the subscribers previous downloads and offers a cheaper subscription rate. Rhapsody has the best radio services, providing specialized stations that stream a pre-set list of music. If you can't decide, then try one or try them all. Each of them offers a free trial subscription. You can experiment with all of them and decide which one suits you best.
