I debated with my friend. Which one is faster - USB or a 7200rpm IDE? I say IDE hard drive.
Thanks

The internal is much faster than USB. That is if you cross the ide channels. Then you can get about 1GB per minute. Now if you go from one partition to another on the same hdd or another hdd on the same ribbon, then it is posible the USB can be faster. Depending on which of the 3 USB speeds is involved.
Understand and agree on this.Quote:

Falcon,
Within the USB 1.1 and 2.0 specifications there are three categories defined for speed (max speed). USB 1.1 provides for what are called "low speed" devices/transfers which have a max transfer rate of 1.5 megabits per second, and "full speed" devices/transfers which have a max transfer rate of 12 megabits. USB 2.0 then adds an additional (but includes the original two) category called "high speed" devices/transfers which have a max transfer rate of 480 megabits.
By default the more recent IDE devices, supporting Ultra 66 type transfers and above, have the potential to be much faster than any device connected via USB as the potential bandwidth available on IDE channels is much higher than on the USB bus. And generally speaking in practice internal IDE drives will in fact perform much faster than external, usb connected ones. However, because there are several factors that can effect actual/recognized throughput it is posible for there to be a situation where a USB attached drive would perform better than an internal one.
Falcon, I appologize for leaving out what the good Dr. posted.
No problem Train.
Thank you to you and Charles too.
I believe he means two separate IDE drives hooked up to two separate IDE connectors on the motherboard.
