How to speed up transfer speeds to a USB2.0 flash drive.

I am using Vista ultimate and trying to transfer data to a 2gig USB2.0 flash drive.

The transfer speed Vista is reporting is 22.8kb/sec.  Yes you are reading that correctly.

86M (Yes Megs) of data has taken 30 min so far and is showing at least 30min more to finish.

Anyone know fixes for this ?

What ver is the USB key. This sounds like you are trying to transfer to a 1.0 device. If not check what version vista thinks the internal usb ports are. Google: how to check version of USB ports in Vista.

Vista gives you the option to set the drive up for quick removal with advanced protection, or sheer performance.

These options can be accessed:

(Right click) my computer >> Manage >> Storage >> Disk Management >>

Then right click on the disk on the lower left/middle >> Properties >> Policies.

Let me know if this does anything for you.

No joy with the quick removal vs sheer perfomance.

By testing different files and transfer speeds it seems to have something to do with the number of files being transferred and not the size.

Transferring 3 files totaling 300MB I get transfer speeds of 3.5MB/sec.  Still no where near the capabilities of USB2.0.  Deleting those 3 items is nearly instantaneous.

Transferring 4,000 small files totaling 86MB gives me an average transfer speed of 30kb/sec.  45 Minutes to transfer 86MB of data.  It also takes 5 minutes to delete this same 86MB.

Is this Vista DRM at work ?

check also in the bios - Asus has an option to set the usb as hi-speed (usb1) or full speed = usb2

Reformat the USB key to NTFS instead of FAT/FAT32. NTFS is significantly faster than the older file systems.

NTFS will not be an option in the format menu unless you ENABLE optimize for performance.

However, Windows still does the precopy B.S. Which is that it announces that it is done copying files before it actually is. If you yank the drive out before it's done the files will be corrupt. The best way to always ensure that the copy job is actually complete (aside from waiting awhile)  is to left click on the USB dealio done by the clock and to click on the drive and click on Stop the USB drive.

Did you try changing the USB port. It might be also a usb port problem.

To isolate the incident if the issue is with the USB drive  or the OS or the USB port to which you are connecting the USB drive.

Try copying the data from a alternate machine if the performance is same then the issue might be with the usb drive itself.

Check by changing the usb ports. and see what is the speed you are getting.
