WHAT IDE HARD DISK FOR SALE?
Integrated Drive Electronics (IDE) hard disks have been around for quite a few years. Prior to these drives, hard disks were interfaced to a PC motherboard via an expansion board known as a hard disk controller. The drive did most of the mechanical stuff and performed basic electronic/servo functions; the controller told it in detail what to do. The development of the IDE hard moved most of the electronics and firmware (low-level software on a chip) from the controller to a printed circuit board on the drive itself. In the process, a buffer/cache' memory was added to the electronics to speed-up the process of reading and writing hard disk drive data. The drive got "smarter." Overall costs went down and performance went up.
A much simpler board, commonly known as an IDE Controller, interfaced the IDE hard disk to the motherboard bus. The term IDE Controller is a misnomer. It is actually nothing more than a bus interface and an interface and connector for the IDE cable going to the drive. The actual controller is on the drive. In most cases when a computer says it has a problem with the hard disk controller, it has a problem with the electronics on the drive. Subsequently, the IDE Controller expansion board electronics and the connector for the drive cable were incorporated into most motherboards. Most of these motherboards have two IDE interfaces--a Primary and a Secondary--each of which can support two IDE devices. The term Integrated Drive Electronics (IDE) is owned by Western Digital. Other companies, such as Maxtor, Quantum, and Seagate, use the term ATA (AT Attachment). IDE and ATA are the same thing. Several standards have subsequently been developed to improve upon the IDE drive and incorporate other devices, such as CD-ROMs which can operate off the IDE interfaces: Enhanced IDE (EIDE), ATAPI (ATA Packet Interface), Ultra-ATA, etc. Today, most hard disk drives manufactured for PCs are ATA/66 drives (ATA/100 is proably around the corner). These drives use Bus Mastering and Direct Memory Access to transfer data back and forth between the disk drive and the computer memory with burst speeds up to a theoretical 66 Mega Bytes per second (MBs) without going through the processor. Older ATA/33 (Ultra DMA) drives do the same thing at 33 MBs. Many existing motherboards still have ATA/33 or even older IDE interfaces. Most ATA/66 drives will work on the older IDE interfaces, but, of course, not as fast. The other major category of disk drives use variations of the Small Computer System Interface (SCSI) and will not be covered in the first publication of this guide.
WHAT IS SATA HARD DISK FOR SALE
The ATA hard disk drives or the Advanced Technology Attachment hard disk drives usually come in Serial as well as the Parallel IDE formats. The Serial ATA is called as the SATA. The concept of the SATA was introduced in the year of 1986. A simple definition of the SATA can be that it can be called as the serial version of the ATA or the IDE interface. This concept of the SATA was ratified by the ANSI in year of 2002. it can be considered as the next generation technology.
The advantage of the SATA is that it has the capability to provide point to point channel communication between mother board or the main board and the drive. Where as in the Parallel ATA that can be termed as the PATA the architecture of the master slave combination is supported on a single cable for the two drives it supports.
The SATA is also used in the implementation of the RAID. The primary reason for the design of the SATA is for the transfer of the data from and to the hard disk drives. The SATA is actually a bus that gives a high performance of data transfer. The data transmission is achieved in the in the half duplex channel.
The speed of the data transmission is about 1.5 giga bits per second or 150 mega bytes per second. This is a unidirectional. Eventually the SATA II was introduced in the year of 2003 that has the speed of about 3 giga bits per second or 300 mega bytes per second. The Parallel ATA hard disk drive uses the flat cable that has the width of around 18’’. But in the case of the Serial ATA a four wire cable is used that has a length of one meter.
This is advantageous in comparison with the Parallel ATA since the cables and the connectors that are used take less space than their counterparts in the Parallel ATA. There are also the External SATA’s or the external hard disk drives that are available. They can be termed as the eSATA. The External SATA is also known as the External Direct Attached Storage for notebook computers or the laptops.
There application is also found in the desktop computer systems, consumer electronics and entry servers. The external hard disk drives whether it may be the External SATA or other drives; presently they use the USB or the IEEE 1394. The usage of these interfaces can compromise on the performance of the drive because they are not as faster as the actual SATA in terms of the peak values.
The important benefits of using the external SATA are explained below. It is very much faster than the other presently available storage devices like the USB 2 or the IEEE 1394 etc. In comparison it is about six times faster. The External SATA is quite robust and also has a connection that is considered as user friendly.
The External SATA also has a high performance. It is also considered as the cost effective expansion storage device. The real advantage is the portability and ease of handling that is provided with the two meter long connectors and the shielded cables that come along with it. The overall performance makes it a popular storage device.
Why hard disks became so expensive from other suppliers..
BANG PA-IN, Thailand — In the neck-deep floodwaters of an industrial zone here, workers are using Jet Skis and wooden skiffs to transport stacks of computer components out of waterlogged factories.

Factories in Pathum Thani Province outside Bangkok last month. Pumps are expected to begin lowering water levels on Monday.
Three weeks after monsoon run-off swamped more than 1,000 factories across central Thailand, the brown, corrosive floodwaters have only slightly receded, leaving the world’s largest computer makers without a reliable forecast about when crucial parts will be available once again.
Consumers worldwide could see increases of at least 10 percent in the price of external hard drives because of the flooding, according to Fang Zhang, an analyst at IHS iSuppli, a market research company. The effect will be less noticeable for laptops and desktop computers, he estimated, because demand has been weakened by the current global economic malaise.
The image of Thailand as a land of temples, beaches and smiles has over the years been reinforced by the country’s tourism advertising campaigns. But the flooding here, the worst in at least five decades, has revealed to the world the scale of Thailand’s industrialization and the extent to which two global industries, computers and cars, rely on components made here.
The world’s biggest names in hard-drive manufacturing, for example, operate from Thailand, where suppliers and customers come together.
Until the floodwaters came, a single facility in Bang Pa-In owned by Western Digital produced one-quarter of the world’s supply of “sliders,” an integral part of hard-disk drives. Over the weekend, workers in bright orange life jackets salvaged what they could from the top floors of the complex. The ground floor resembled an aquarium and the loading bays were home to jumping fish.
“Surely one of the inevitable impacts of this is that never again will so much be concentrated in so few places,” said John Monroe, an expert on storage devices at Gartner, a technology research firm. He estimated it would take a full year for hard-drive production to return to preflood levels.
The shortage is not entirely bad news for the disk-drive business, especially for those companies whose facilities were not damaged, such as Seagate, which has a factory high and dry on a plateau in northeastern Thailand. Mr. Monroe said price increases will help lift industry profit margin to about 30 percent from about 20 percent before the floods.
The flooding, which is now spreading through the northern reaches of Bangkok, is the second reminder this year of the vulnerability of global supply chains, coming just a few months after the earthquake and tsunami that struck Japan and shut down facilities that produce crucial car electronic components.
Thailand became a hub for Japanese car manufacturers in the 1980s and 1990s, partly because car makers sought to escape the punishing effect of a rising Japanese yen.
Today, as a measure of Thailand’s importance to the global automotive supply chain, the flooding has forced Toyota to slow production in factories in Indonesia, Japan, Malaysia, North America, Pakistan, the Philippines, South Africa and Vietnam. Honda, the carmaker most affected by the Thai floods, has also slowed production at factories in several countries.
The initial forecasts of damage to the auto industry were too optimistic, said Hajime Yamamoto, the Thailand director of IHS Automotive, an automotive market forecasting company based in Detroit. “It’s getting even more serious than what we expected,” he said. “Every week we actually revise our estimate for the scale of losses.”
Mr. Yamamoto predicted that car manufacturers and their suppliers would seek to diversify their operations to other countries.
“They will try to balance their expansion so they don’t have concentration of risk in Thailand,” said Mr. Yamamoto, who named Indonesia as a place Japanese suppliers were likely to expand.
