SATA Hard Drive

SATA stands for Serial Advanced Technology Attachment and is the newest technology for connecting internal hard drives to motherboards. In the past, Parallel ATAs Attachments were the standard, but SATAs have eclipsed the PATAs in both performance and the fact that SATAs do not contain wires. SATA technology also costs less.

SATAs are designed for easy installation. Each disk drive has a cable that connects to the device, which you connect to your motherboard. If your motherboard supports it or if you have the proper adapter, you can have PATAs and SATAs coexist on your motherboard. You can use SATAs in either Windows or Macintosh operating systems. To install, you will need your motherboard and SATA, a compatible power adapter, an interface cable, four 6-32 UNC drive mounting screws, and a Philip’s screwdriver.

Shopping for a SATA hard drive can be confusing if you don’t have all of the information. It is essential to know of the various drives before hitting the stores. SATAs are faster performing and are well suited for applications that require a large amount of bandwidth. SATAs can be connected and disconnected without having to shut down, wait and restart the computer. They are also easier to install without causing damage to the fragile insides of a computer.

The insides of a computer are very fragile. Be sure to turn the device off while you install, and do not jiggle or drop the disk drives. More importantly, removing these drives voids any warranty you may have on the computer. After attaching one end of the device to the motherboard, all you must do is attach the interface and power cables, then screw in the mount screws. You will also have restart your computer and configure the BIOS. After the computer starts, you have to run the system set-up program, instruct the system to detect the new drive, then you must save settings then exit.

If you need an extreme amount of space or need to immediately back up your information (or both), you may want to consider the Redundant Array of Independent Disks (RAID) system, which hooks up two or more drives at once. There are different systems to use, depending on id you are looking for speed, data protection or both.

SATA is now the prevailing format of internal hard drives. Below are some favorites:

  • The Western Digital Caviar Green 2TB is a good pick for those Earth-friendly computers that run on less power. Cache sizes include 32 MB and 16 MB and capacities include 1-2 TB and 500-750 GB. Power consumption of this device is about 40% less than that if its competitors. Features include IntelliSeek, NoTouch and Intellipower. With this device, you can have an external hard drive without the need for a fan. IntelliPower is a combination of spin speed, transfer rate and caching algorithms. InteliSeek determines the optimum speed to get the job done and uses only that. The NoTouch feature endures that the device never touches the disc, meaning less wear and tear. Perpendicular Magnetic Recording (PMR) promotes a larger areal density and StableTrac secures the motor shaft to stabilize the device. Because the spin is lower powered, more energy is saved.
  • The Hitachi DeskstarTM 7K1000.B 1TB is also a good model for those who are trying to lower their power consumption; it is very power efficient and sports the ENERGY STAR seal given by the Environmental Protection Agency. This device boasts up to 43% in power savings on idle compared to similar non-efficient products. The device’s full encryption protects your data. The device also promises a strong performance for both home and office use.
  • The Western Digital VelociRaptor 300GB boasts of speeds up to 35% faster than those of competitors, with 10,000 RPM, 3 GB/s and a 16 MB cache. With such a high capacity and 1.4 million hours MTBF, this device promises high reliability. An IcePack mounting frame cools the drive and NoTouch technology ensures that the device never touches the desk. This is a good device for computer enthusiasts, work stations and servers on the lower end.
  • The Western Digital Enterprise RE3 1TB offers a 32 MB cache at a speed of 3 Gb/s. Dual processing improves the performance of this device by 20% compared to its previous version. A StavleTrac feature secures the motor shaft on both ends to promote stability, and a RAFF features monitors vibration, yielding a 60% improvement from previous versions of the device. This device also has the IntelliSeek and NoTouch features. This is a great device for servers, video surveillance and other intensive writing applications.
  • The Western Digital Caviar Black 640GB boasts a dual processor, a 32 MB cache, the StableTrac, NoTouch and ShockGuard features and a 5-year limited warranty. A LifeGuard feature protects the device from shock and other environmental issues. his is a great device for computers that incorporate multimedia, video and photo editing and gaming.
