You have to know about this component, if you're looking for a 1.5 Tb internal Hard Drive. These two would be highly recommended to pick up. The fact is theres a bunch of brand you could choose, but with the purpose and by its good feedback from people who has use this, you can look over them and even to try it.

1. Samsung's Spinpoint F2 EcoGreen
2. Western Digital Caviar Green WD15EADS

These are green series from Samsung and western digital. These two work on their own advantages. If you want the best it can be for your operating system to be hosted, file swapping, and temporary files for application, then the need of speed performance has to be in advance. Main function of Hard-Drives is to storage your file. The bigger capacity its have, more files that could be save in. But its also to be concerned is about the power of the hard-drive consume. Samsung and Western green series aim for this matter.

Both of them is good at speed for media storage. Video and others are okay to proceed. But Western have faster respond and work nicely for small files. Then, for the sustained transfer rate, Samsung had better than Western Digital. Also the platters that Samsung used was 3 compare to Western that use 4 platters. These green series also lesser noise, even some people said it was quite enough. Consuming lesser watt on hard-drive maybe seem go for nothing. But underline that the factory must be released a hundred million of unit over the world. By that fact, its hope to reduce electrical consume significantly.

There are others kind of 1,5 Tb internal hard drive. Such Seagate LP or Seagate 7200.11, but unfortunately the 1,5 Tb drive they made not too good as for media storage compare to Western Digital and Samsung. As for Seagate LP, the drive is hotter while run, consume more power, and using 4 platters. Actually they can made it to three but somehow they don't. The second are Seagate 7200.11 that have a lot bad feedback by people who use it. So just pass this type. From just byte to kilo byte, evolving to gigabyte then now terabyte. Starting by lesser electrical consume hard-drive, maybe someday there would be non-electrical use monitor. It good that industry try to save the earth by simple ways such electrical consume. Perhaps the next generation would be using recycled material but better at performance. We hope so, then a city like Jakarta for example could be less hot than now.
