hard drive performance gain?

The 400GB Barracudas that I have (One 7200.9 the other is a 7200.10) are both dogs in terms of desktop performance/responsiveness. My two WD5000AAKS are much better, and those are drives with only 16MB of cache, and I'm pretty sure the seek performance on my WD drives isn't as good as the Caviar Blacks.

If you were to conduct a disk limited test (creating an ISO file, a decompression test, loading a game level etc) I'd bet that the 640GB Caviar Black would turn in performance about 20 to 30% faster than your current Barracuda.

good deal i guess it would be a good upgrade
 
im guessing that the 750gb is the same in performance just different size

Not really; the 640GB is of a newer generation with higher density platters so it is faster than the 750GB.

I wouldn't be totally sure of this. The 750GB drive could be a three platter/five head drive on the same 334GB platters as the other Caviar Black drives, it would simply have one of the platter faces disabled. It's a common cost cutting measure, as it allows drive makers to use platters that have a defective side, much as AMD harvests defective Phenom II X4 dies and sells them as X3s.
 
i mean would it be worth sacrificing the extra space i would get from the 750 for the speed difference of the 640?

As I said above, and have found verification in this PDF: http://www.wdc.com/en/library/sata/2879-701276.pdf

The 750GB is a 3 platter 5 head drive, meaning it use the same platter density as the other members of the Caviar Black family. If the 750GB Caviar Black only had 250GB platter,s it would be a 3 platter 6 head drive.

The 750GB will be faster than the 640GB, though the difference is very small, as the only difference is the larger capacity.
 
what software is better to use? Acronis® Migrate Easy 7.0 or True Image?
 
wierd i cant get the drive to show up in the disc management tried usb and firewire
