7200 rpm portable hard drive image
Sandra L
am looking at the portable hard drives with 500gb and there are many brands and I am unsure which ones are good ones and which ones to stay away from. They are all in the same price range. They are samsung, toshiba, western digital, a-data, lacie, seagate and dane-elec. Any info on these would be helpful.
Answer
The interface matters the most and you probably want 7200 RPM instead of 5400 RPM, unless you use the external hard drive infrequently and want to save power. Do you have e-SATA, firewire ports, or USB 3.0 ports? Note that USB 2.0 is standard now and few people have 3.0 yet.

What is the difference between an external desktop HDD and an external portable HDD?

I am in need of backing up my laptop hard drive and while doing research on external storage, I noticed desktop HDD's are cheaper than the portable ones. What are the key differences between the two? From what i understand, speed is a selling point, but how important is that? I only need one to back my laptop cause starting to go down hill.
Answer
As you say your laptop HDD is going downhill, you'll need to have it replaced and you CANNOT replace it with an external HDD. External HDDs are mostly for backups. Windows cannot boot from an external HDD.
Difference between Desktop and Portable HDD
--------------------------------------------------------------------
The difference is in physical size (dimensions) and operating speed. External desktop HDD are simply the kind of HDD you would find in a desktop PC enclosed in a case with USB or Firewire (1394) connectivity. The same goes for external portable hdd which is simply a laptop hdd in a case.
As for storage capacities, they both have the same capabilities. Operating speed is the difference. A desktop hdd operates at 7200 rpm (rotations per minute). Some newer drives operate at 10,000 rpm. A laptop HDD usually rotates at 5400 rpm. There are two reasons for the lower speed: to increase battery life of the laptop and to reduce heat output/heat generation because higher speeds cause more heat and keeping laptops as cool as possible is paramount.
There are now new HDDs known as Solid State Drives (SSD). These have no moving parts and so require less power and produce very little heat. However, SSDs cost a bit more over a traditional HDDs. At any rate, I'll advise that you go for a portable model as they are smaller in physical size and they still have high capacities; as high as 1 Terabyte (1 Tb)
Good luck.
