Drive Features
The WD6400AAKS boasts of a huge 640 GB capacity - large enough to store everything you throw in it. The large capacity is advantageous also because of the growing size of operating systems - Vista takes over 6 GB in the basic install, while the upcoming version of Windows may take even more. Versions of Linux also take huge amounts of space.
We also tend to dump everything we get from friends or download TV shows, movies, games, and software (thanks to our "Broadband" connections) onto the hard drive and never bother to delete it, so a smaller hard drive always ends up running out of disk space. It is therefore logical to go for a huge capacity hard drive like this when you purchase a hard drive.
This 3.5-inch drive features perpendicular recording technology, meaning a greater areal density - more data per given area of the platter, thus reducing the number of platters, which in turn, reduces the amount of heat it generates. Speaking of platters, we have two in here, each with a huge 320GB. The spindle has a rotational speed of 7,200 rpm and the drive has a large 16 MB buffer for uninterrupted data transfer.
As you can see in the above photo, the drive features a SATA interface - this is the faster and now common 3.0 Gb/s SATA-II.
A very small part of the green PCB is exposed from below as you can see in the above picture.
This drive features ShockGuard technology to protect the drive mechanics and platter surfaces from shocks. In addition to this, there is the NoTouch ramp load technology that parks the recording heads while the drive is spinning up or down or when it is off, thus eliminating the chances of the recording head touching the disk surface. This improves the life of the drive and makes it more reliable.
To enhance the reliability of the drive, there is Data Lifeguard - a set of data protection features that include shock protection, environmental data protection and real-time embedded error detection and repair. Data Lifeguard technology automatically finds, isolates and corrects problems that may develop over the life of the drive.
The drive features WhisperDrive advanced acoustic and power-reducing technologies that make it operate very silently even during the high-stress mode of operation while benchmarking. To cut seek noise even further; there is the SoftSeek technology that streamlines read/write seeking algorithms, resulting in more efficient operation.
Like most WD drives, it too features Intelliseek - an algorithm that calculates the optimum seek speeds to lower the power consumption, noise and vibration. All this translates to a lower power consumption, to help keep down your electricity bills, especially if the PC is on 24/7, and a silent hard drive that is a boon for any HTPC.
