64GB Cruzer Freezes Finder on Macbook Pro

I know that the Cruzer flash drives are slow. That much is painfully obvious. What I don’t understand is why my Cruzer 64GB drive causes Finder to become unresponsive on my Macbook Pro (2.8 GHz i7; 8GB memory) every time I transfer a file. It seems to me that, like any other flash drive out there, the Cruzer should simply transfer the file in the background while I go on about my business. Were that so, I could tolerate the slow transfer rate. But the fact that I have to wait for the file transfer to complete before Finder is freed up for other uses is absolute bull**bleep**. 

Who makes Finder?  Have you written to them and asked why their app works that way?

Are you using SecureAccess by any chance?
