Thread: Memory card speed: Does it make a difference?

Yes friends,
Another words, chain is strong as the weakest link.

My experience with USB2/USB3 memory sticks is that all 2.0 sticks used on 2.0 interface are slower than interface itself.
Best of USB 2.0 memory sticks I'm using (not ext HDD) have about 15 MB/s read and about 8 MB/s write speed, when HDD connected on same port have about 33/25 MB/s.
Not to mention some others that have speeds about 8/3 MB/s (R/W), so they are "the weakest link" in chain.
When USB 3.0 sticks are connected on same port, speeds are as with HDD, another words maximum for that physical interface.
My conclusion is that using memory device faster then interface will allow to get interface maximum performance, because now interface becomes "the weakest link".

Worth to try.

P.S.
At last, this cards a not expensive any more
