Does USB drives need high 4k write speed?

Economic USB 3.0 memories may have high sequential write speed, but they always have very low 4k write speed (like the Patriot Flash XT). I have difficoult to find an economic usb drive that is performant in all kind of speed.
But I would use USB only to transfer file from one computer to another, or run operative systems. Are this kind of operation influenced by non sequential write speed?
If so, i don't take the Patriot and I take the Sandisk Extreme 16GB, that it seems to me the best for performance/price.
