Data Transfer Rates
Data written on a hard drive is encoded not as human readable language but rather a series of 1s and 0s that represent a Bit or Binary Digit. This is the only language that the computer understands that is why it is commonly referred to as machine language. Commonly, files have a property size of xx KB (kilobytes) or xx Byte, a byte consists of eight bits which represents a character. Data transfer rates is the velocity at which data is transmitted from one device to another.
In IDE hard disk specifications, it is commonly seen that a data transfer rate is xx ms (microsecond). Essential, the lower the data transfer rate, the faster the hard disk can read and write on the media and retrieve data that is requested by the user or a software application. The data transfer rate allows for faster execution of tasks sent by the user to the computer system.

The normal process of the platters is to spin up once the hard disk is started and keep spinning. The spinning course is the most tiring part on the spindle motor of the hard disk. A lot less effort is require maintaining the speed of the spindle. To get the maximum performance of the hard disk is the keep it on spinning. Before the hard disk can read or write it need to spin up on full speed.
When the hard drive is spinning down it doesn’t only reduce power consumption at the same time it reduces the thermal output. Thus, spinning down the spindle increases the longevity of the hard disk.

With the growing popularity of portable devices, IDE hard drives are also following suit. With the development of External Hard Drive Enclosures, anyone can carry around his hard drive and have the capability of connecting it to any computer system via the Universal Serial Bus (USB) port. This type of enclosure is compatible with USB 2.0 as well as the USB 1.1 standard. Major operating systems like Microsoft Windows and Mac are compatible with the device which allows for easy identification and integration. The enclosure is capable of transferring data with speeds of as high as 480 Mbps and can accommodate all 3.5” types of hard disks. This device is also fitted with an LED indicator to help the user monitor hard disk activity.
Compact Flash Adapter
With the introduction of the Compact Flash Adapter, anyone can now make use of a CompactFlash memory as a primary hard drive function for a computer system. As opposed to the traditional hard drive, this has no moving parts like spinning disks or wobbling bearings. This gadget provides the functionality of replacing traditional hard drives with economical and rugged CompactFlash cards that uses the same IDE motherboard interface like regular hard drives. Any system equipped with a standard 40-pin IDE connector can use this technology. This solution does not require the installation of additional hardware drivers and can be used as a primary boot device that contains the computer’s operating system.
Epson QX-10 IDE Drive
There was a development undertaken a few years back that was geared towards creating a control chip to be utilized by system independent IDE host adapters. The Epson QX-10 was one of the devices used in this experimentation wherein it was fitted with an IDE hard drive. The developed interfaces were primarily simple in order to make some minor BIOS setting changes easy. A Western Digital WD1002-HDO was used with 95% of its driver routines being able to correctly control the function of the hard drive. The minor revisions done included the addition of a single sector number to the IDE where it starts at sector 1 instead of the default sector 0.
Hard Disk Role in Computer System
The hard disk possesses a major role in the various aspects relative to the operation of a computer system that includes:
Performance hard disk is important in determining overall computer system performance because the speed of boot up and loading of software applications are directly affected by the speed of the hard disk. It is equally vital during multi-tasking operations or processing large amounts of data;
Storage Capacity obviously, being the main storage device, a higher capacity allows for storage of more data and programs;
Software Support with inflated operating system files and software applications, the hard disk provides critical support to their stable performance;
Reliability good quality coupled with smart maintenance and back up will help protect your data.
WD Notebook IDE Drive
The Western Digital Scorpio is a 120 GB IDE hard drive which measures a measly 2.5” but delivers world class performance with very little power needs as compared to slower types of notebook hard drives. This drive is characterized by its 5400RPM lightning quick performance which has the power requirements of a 4200 RPM drive that translates to better readability. With the use of the exclusive WhisperDrive expertise coupled with SoftSeek algorithms, it produces the quietest performance for any drive in its class.
The WD developed ShockGuard protection prevents damage to the platter and drive mechanics that may be sustained from unavoidable shocks. The heads are locked in a secure position with the DuraStep Ramp technology of WD.
