I have two 4GB flash drives, both bought from SVP, a Freecom DataBar
http://svp.co.uk/products-solo.php?pid=1389
and a Integral Courier
http://svp.co.uk/products-solo.php?pid=440
and I've not encountered any issues with either of them.

My old Vaio laptop used to run 2.5" USB hard drives ok, but my Toshiba,
Compaq and JVC laptops all fail to power either of my 2.5" external drives
without some sort of power boost, either a powered hub or cable with
second USB/PS2 mouse connector. However I've not experienced problems with
any of these machines running a 4GB flash drive.
