Every hard disk is interfaced in the motherboard through a disk controller. This disk controller is the one that plays bridge between the hard disk and the operating system. For the user to access data from the hard disk, there is a data bus connecting the hard disk and the motherboard. The data bus is like a pipe where bytes of data are being transmitted.
There are two kinds of data buses, Serial ATA and Parallel ATA, which are used in SATA hard disk and IDE hard disk respectively.
IDE is the abbreviation of Integrated Device Electronics. The Parallel ATA was earlier called IDE. Thatís why hard disks that use Parallel ATA are called IDE hard disks.

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 extension board known as a hard disk controller.¬† The drive did most of the mechanical stuff and performed essential 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, usually identified as an IDE Controller, interfaced the IDE hard disk to the motherboard bus.¬† The term IDE Controller is a misnomer.¬† It is really 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.¬†¬†
Knowing the different parts of your computer is essential especially if you come across some problems while using your computer. Even if your computer is broken, at least you still know how to recover your files and documents through the hard disk.
What is a hard disk? This is commonly known as the disk drive where large amounts of data are stored. With recent developments in technology, computers have gigabtyes of storage. It only means that you can now store more files, documents and other data. This unit has a set rotation speed. It varies from 4500 to 7200 rpm whereby the access time is measured using milliseconds.
When you computer crashes down, you can still retrieve the pertinent data files that you have. It is just crucial that the hard disk is still working and intact. You can remove the hard disk and place it another computer for you to recover the files.Filed under Information | Comment (0)
Seagate, the big American data storage company has recently announced that they are launching one of their best products to date, they said that it is the industry’s first ever 4TB video hard disk drive. This hard disk drive is 3.5 inches and it will cater to people who need video applications. These applications include surveillance systems, digital video recorders, STPs, etc.
The company said “Purpose-built for video solutions, the Video 3.5 HDD can store up to 480 hours of HD content making it the industry’s highest-capacity drive designed specifically for video,”¬†What is impressive about this product is that it can support up to 16 HD video streams which is equivalent to 20 standard video streams, which makes it bigger than their competition.
There is no exact date as to when this will be available in the market, pricing has also not been announced but it is expected soon. For more information on this product, click on this page.
Western Digital, one of the world’s computer hard drive manufacturer has reported that they had better third quarter revenue, better than what the company has expected. They said that the increase was made possible by the high demand of enterprise customers. It has now dominated the hard disk market. The need for hard drives has been surging continuously because the demand for computers does not stop. It just increases in time.
Analyst have predicted something generally less because people have been choosing the use of smart phones instead of personal computers but it seems that that Western Digital will still be doing a lot of business. PC sales fell to 14 percent during the first quarter of 2013, this makes it the biggest dip for at least two decades but it doesn’t affect the sales of the hard drives. People who are not buying computers already have theirs at home and they still need more storage.¬†
Here’s something completely impressive. A different style that has a purpose.¬†¬†If you’re interested in having four very unusual terabytes sitting on your desktop, then Lacie’s Blade Runner Drive is exactly what you are looking for. This special hard disk drive was designed by Philippe Starck. Starck is a famous French product designer whose¬†notable designs include an optical mousse¬†for Microsoft and¬†several yachts including the $300¬†million A¬†and even new packaging for a beer company.
The custom-biult 4 TB USB 3.0 drives are being produced in only in a limited edition so if interested, you must be fast to order one. When asked about the product, designer Starck said :¬†”The warm interior electronics are encased in a mystifying shell, and the blades are the radiator that cools it down.¬†The suspension gives space for air to circulate around the hard drive, and the metal material increases the temperature conduction.” The product will be for a retail price of $299.
A normal computer today would normally come with one or more hard disks. These hard disks do one very important thing which is necessary for majority if computer users, it stores digital information. It also provides access to to large amounts of data. It works as simply as a cassette tape, wherein files/data can be erased, re-written and can even remember what has already been stored in the past. All data that are stored in a disk are in the form of files. A file is a string of bytes. It can be in a form of different things such as images, texts, software application and so on. When a program running on the computer requests a file, the hard disk retrieves it and sends them to the central processing unit one at a time to be accessed. The bigger the capacity of the disk drive, the more files you can store. The bigger the capacity of the drive, the faster the computer can run as well.Filed under Information | Comment (0)
This year has been the unveiling of 4TB hard disk drives. Companies have been pushing for better and bigger storage and better performance. Both Toshiba and Western Digital has released their new products towards the end of the year.
Toshiba said “The range has been developed with the storage challenges presented by big data and cloud services in mind,” It is 50% increase in storage capacity than the last ones they have produced and 18% faster too!¬† The sample shipments will be available beginning this month and a bulk produce by the New Year.
Western Digital 4TB WD Black drives have maximum capacity, says Matt Rutledge, VP of Western Digital’s client storage group. He continued on ‚ÄúMaximizing the features and functionality of power computing applications such as gaming, multimedia and video editing, the new WD Black 4 TB hard drives offer capacity and performance ‚Äď without compromise.”
Both of these products are expected to drive sales by next year, making the future of hard drives more impressive.Filed under Information | Comment (0)
Laptop and Notebooks are making strides like never before this year. Therefore, one of its major components needs to change or, in this case, shrink but retain its memory size.
HDDs apparently represent the most expensive component in a netbook system, as CPUs, LCD panels, optical disc drives and batteries mostly fall between US$20 and US$25 each, while a 2.5-inch HDD can go for as much as US$43-45, a perfectly good reason for trying to lower the cost of these specific components. The three storage companies are said to be focusing on minimizing the cost of the drive’s ICs, magnetic platters, and pick-up heads. Storage capacities for the lower priced hard drives are to fall between 80GB to 120GB, on the condition that the price cut is effective.

I’m no longer surprised whenever something so advanced and high tech comes up. I’m always impressed but no longer surprised. Just this month in Singapore, researchers have developed one of the world’s thinnest hybrid hard disk drives with storage capacity of over 1 terabyte. Woah, right? A typical hard drive is 7mm thick but this one is only 5mm thick. It has bigger capacity too since the typical ones can only store 500 gigabytes. Its perfect for tablets and ultrabooks.
It is called “A-Drive” is a hybrid hard disk drive. It costs less and provides more storage space. How much more? Well it can easily store 250,000 songs!¬† It is expected to cost around $60 when it comes out soon. There are no exact dates when this product will be available in the market.been developed by a team of researchers from the Data Storage Institute (DSI) of the Agency for Science, Technology and Research.Filed under Information | Comment (0)
