portable hard drive 7200 image
Josh
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.

where can i store all my music cds and photos instead of in my laptop?
count aluc
Whats the dif between portable hard drive,flashdrive,memory stick...I have about 300 cds & 1000 photos.
Answer
wait, lets see volumes first
300 cd's @ 700 mb each > 210 gb
1000 photo's ain't that much, but you could add 10 gb
so in effect you presently have 220 gb of storage to handle
jolly well forget flash drives and memory sticks and all
4 gb to 8 gb is all that you can realistically expect
and we are left with the other solution > portable or external hard drives
something in the range of 500 gb to 1000 gb ( 1 tb ) is what you should be aiming for, cause your collection is going to expand ... looking into the future i mean
500 gb
