What sort of speeds should a USB2 drive give?

Just got a 120gb Maxtor One Touch external USB2 drive and thought I should test that it's working ok.

What sort of speeds should it give on the benchmarking? I just got a drive index of 10304kB/s. Is that too slow?
Is that kilobytes or bits? How do I calculate the speed?

Thanks

Divide by 1024, get MB/s. Your 10MB/s is OK, but not great. It IS faster than USB 1.1 (which is only 10 megaBITS per second). I've seen 20MB/s on my friend's drive using my PC.

So bearing in mind that the drive is a 7200rpm (120gb) drive, I should get more out of it shouldn't I?

Of course you should, but it also depends on your enclosure. Tom's even did a comparison, not all USB drive enclosures perform the same.

Sorry, what do you mean by enclosure?

If you mean the actual drive mechanics, it's a sealed USB unit. The Maxtor (Onetouch) literature at http://www.maxtor.com/en/products/external/onetouch/one... says it's got a bus transfer rate of up to 480Mb/sec & a sustained rate of up to 34MB/sec.

The USB2 controller I have a a PCI one (this http://www.ebuyer.com/customer/products/index.html?acti... ), apparently with a via VT6202 chipset. My mobo is an Abit KT7A-raid (also with a via chipset).

theoretically (in most cases) USB2 is a good thing, but practically Firewire is better solution for an xturnHD. Anyway, 10 MB/s is a good thing, it is the same as 100mb PC2PC network performance, which in my book is an xcellent going.

..this is very useful and helpful place for information...

by da way, "enclosure" is dat thing dat yer HD sits in - a box which holds HD. hope dat helps.

Not to forget that networks and USB are measured in mb/s, while hard drives are measured in mB/s. USB 1.1 is 12 megabit, which is only 1.5MB/s. And most networks are 10/100 megabit.
