Cheapest External Hard Drive 1TB

What is a 1TB hard drive Good For?

Hard drives in the computer store data and let you get it back whenever you need.A 1TB hard drive is a special variation of this device, it lets you store 1 Terabytes of data, or 1000 gigabytes.

Hard drives have been using a magnetic principal to store data for the last few decades. It involves a metal disc coated in a layer that holds magnetic status set by the head hovering just a whisker above the surfaces.

These heads are able to determine the bits passing under them while the disks spin away at 4200, 5400 or 7200 rounds per minute in conventional hard disk. This bit is interpreted by internal electronics and then passed on to the motherboard where the operating system can catch it and finally find out what file it is and where it is supposed to go.

A terabyte is a measurement unit for data stored. This is 1000 Gigabytes or to make it more tangible, you would be able to store 220 one sided DVDs on a HDD this big. That’s the capacity of 125 8GB iPods, or equal to 225,000 good quality mp3 tracks. It is enough for most people to store all their albums, movies and documents at home. And if they ever run out of it, there are 1.5TB drives and another 1TB hard disk drive is not very expensive either.

There are two kinds of connectors you should be aware of when you choose a hard disk. The first and oldest connector is the PATA. You will be able to tell it, because it’s about 2 inches wide and has 80 wires running in it. It’s being phased out in favor of the SATA. The sate connector and cable is about the same as a USB connector and cable. It’s faster, more reliable and the controller electronics is more sophisticated. Most modern motherboards and hard disks come with this, if you have the connector, get SATA hard disk drives.

Sata hard disks are faster in data transfer and the manufacturing prices of cables are also lower for obvious reasons. A 80 copper wire cable requires more material while SATA only uses 7 wires.

A 1TB hard drive is slowly becoming factory standard for even OEM computers, it’s the new common capacity. If you’re after a new model because your old HDD died, or simply ran out of capacity, refer to forum threads and reviews before purchasing one. You are going to save yourself some frustration.
