external hard drives.....rpm speed vs bus speed?
bastian915
wanting to get an external hard drive for my laptop....looking at different manufactures and wondering if at a fairly good bus speed like in the Firewire 400 connection if there really would be much difference between 5400rpm and 7200rpm. I'm just wondering because the portable bus powered hard drives seem to come with 5400rpm and the desktop versions can go a bit faster.
Hey wizard of OZ thanks for the post....wondering if it would then be worthwhile (since the laptop only has firewire 400) to get a firewire 800 express card for the faster bus speed.
Answer
To start with the drives in external hard drives are the same as you have in a desktop. The difference between 5400rpm and 7200rpm is that the faster you turn the disk platters the faster you get to the data and reduce something called rotational delay which can be most the the time to retrieve data from a drive or write to it. The reason the bus powered drives are slower is that the slower drives take less power. Any external drive is going to be slower than an internal drive because even Firewire is not as fast as an internal bus connnection.
Bottom line it probably does not matter which you get because you should only be using an external drive for backup or moving data via sneaker net. I would suggest that the faster bus is your best bet though.
