External USB HDD speed

[xeonzx86]

can anyone suggest me some utility to benchmark my external USB hdd (using a seagate 120gb/7200 with a USB2.0 case) .
wat is the speed diff between usb2.0 and usb 1.0.........my transcend flash never gives me speeds above 8 mb/s...

HDtach will do a good job.

usb1.0 1.5 megabits/sec (187.5Kbytes)
usb1.1 12 megabits/sec (1.5Mbytes)
usb2.0 480 megabits/sec (60Mbytes)

Those are maximums of course, which you never actually get.

you are highly unlikely to encounter USB 1.0 unless you used really, really old systems, talking about Socket 7 class, or AT systems. Remember this, when you use USB it is going to hit your CPU, and this can directly affect the transfer rate if it is having trouble handling it

that is why when i was using USB HDD on a celeron 1.2ghz system speeds as well as transfer speeds are very low......

i used hdtach...........it shows my external hdd(seagate 120gb baracuda) speeds as 1.0mb/sec. this system which i am using is
celeron 1.2ghz
128MB ram
810e mbd

is it because of such low config speeds are so low??

Sounds like your HD is on a USB 1.1 port then. Look in device manager at your USB ports. You should see the word enhanced for a high speed port, or it will actually say USB 2.0.

You can always add a USB 2.0 card to get your HD going a lot faster. My WD 40Gb external HD averages about 17Mbytes/sec on a USB 2.0 port. That's with a P3 1.2Ghz Tualatin.

On one of my systems.

External USB2 Hard Drive to ATA 133 HD that sits in 2.6GHz CPU with 1GB memory.

5 sec. to transfer a 100MB file using WinXP with regular software.

That means 20MB/sec. x 8 = 160Mb/sec. (B=Byte b=bit).

:sun:

i checked that mbd didn't have usb2.0 support................so i checked on a thinkpad....there my drive gave avg 19mb/s
burst 24mb/s

while with usb1.0 it was not givin any speed morethan 1mb/s

thanks

well its actually usb 1.1 are you rating those speeds in megabytes or megabits? there is a big difference in that case, you can always upgrade the Celeron with a usb 2.0 card if you think it is really worth it
