Copying 4GB from a USB flash drive to my Linux partition. The flash drive is NTFS formatted (I believe, it's Windows formatted). The transfer is incredibly slow and blocks the computer frequently causing lag and hanging applications.

My transfer rate is 1.2 MB/sec and that is the max it has hit when I let the File Operations window have focus. I can do the equivalent operation on my windows machine at 100MB.

Why is this so slow under Ubuntu and significantly faster in Win 7?

NOTE: I installed Ubuntu from Windows using the Windows Installs as a Dual Boot option. Does this process use "Ramdisk" or some weird thing that might be causing this?

Thanks, read the question but it doesn't explain why I would get 1.2 MB transfer rates when I can do the equivalent operation on my windows machine at 100MB. – kingdango Dec 15 '12 at 20:50

In windows it works because ntfs is main system of Windows and was created for Windows. For flash drive i use fat32 for transfering files between linux and windows. Works good in both, and ext4 for saving my main files. It works fast and its secure.
PS. I posted this because couldn't write answer in old comment

I'm not sure this is the case. In fact, I'm starting to wonder if there is some "feature" (perhaps Ramdisk?) used because I installed while running windows as a Ubuntu/Windows dual boot install. – kingdango Dec 16 '12 at 23:29
installed from windows - you mean wubi? If so, Its very buggy. Its only for testing ubuntu and then uninstalling. If you want to use ubuntu you must burn iso file that you downloaded from to dvd or usb flash drive. Then boot it and install ubuntu. – Emin Mastizada Sep 12 '13 at 20:08
