Query: Very small, but...

I love the small form factor of these tiny usb drives; but, I really hate how very slow they are. The throughput is extremely slow compared to all the other usb drives I have. I have Sandisk, A-Data, Ativa, Verbatim, and a no-name usb drives and all are many times faster than my 4gb Sony Micro Vault. To load up 3-4 gigs, it takes several hours. To do the same on my 4gb Sandisk or 8gb A-Data, it is less than an hour.My tech experience is very high. My testing was done on a Vista Ultimate 64bit laptop. I also have 2 2gb Sony Micro Vaults and they are just as slow. But at 2gb, it was not such a big deal.If you just want something very tiny, then this is ok. But if you really also are concerned with performance, then buy something else. I recommend Sandisk.Scott
