I recently upgraded my system from Vista to Windows 7 taking the oppurtunity to install some new Seagate hard disks at the same time. I had stored some files on a Corsair 32Gb USB 2.0 memory stick before doing this. At present the system is a clean install of Windows 7 with Kasperski AV and the XP Mode virtualisation option installed and fully updated by Windows update. I have also created a Windows 8 VHD file on the C: drive and installed the boot from VHD option in order to try out Windows 8 as well. It is a 64 bit Quad Core i5 machine.
In copying files off the the Corsair USB stick I am finding files typically take between 3 and 5 times longer to be copied to disk then they do when the operation is carried out on a Vista or XP machine. In order to test this further I reconnected my old hard disks with the old Vista OS still intact on them and tried the copy again. Takes about 3 -5 minutes under Vista but 30mins to an hour under Windows 7 for the same files. I also noticed that the deeper and more complex the directory structure being copied the more Windows 7 seems to struggle with the transfer.
Having read through a huge number of user reports/solutions(?) from people who seem to be struggling with the same or similar issues I have tried switching the policy for the USB drive in device manager to 'optimise for performance' and also turning off the Background Intelliget Transfer service off through Administrative Tools under Windows 7 with little appreciable positive effect.
From a review of the answers given so far to those with similar problems I have the feeling that various red herrings are deliberately being thrown out in the replies by MS staff in order to try and cloud the issue. As a result one is left with the feeling that Microsoft know there is an issue but don't want to admit to it as they have not got a solution at present. I hope I am wrong. Also from the replies given I get the impression that a similar issue seemed to exist in the early releases of Vista and had been resolved by a later update. Has an old issue been re-introduced in the current Windows 7 build?
Can anyone provide a solution that gets a reasonable response out of USB sticks under Windows 7?
