PNY Technologies USB2.0 CF Reader - PNY Technologies USB2.0 Single CF/SD Readers
So far so good, but what about the overall performance? If we take a closer look at the following results it’s clear that the type of memory media used makes a real impact on transfer speed. As with most quoted transfer speeds you’re not always going to get the performance stated on the box. In fact, my high-speed 40x CompactFlash card produced a sustained sequential write speed equivalent to around 30x. Obviously, if you’re limiting yourself to a USB1.1 interface then that standard will affect the transfer times, regardless of the speed rating of the card.
So, as with the majority of USB2.0 card readers, you’re only really held back by the quality and rating of the memory card you use. That said, when using my high-speed card in this reader I did gain about five times more transfer speed in the jump from USB1.1 to 2.0.
All in all, there’s little to fault here, apart from the plastic build quality. Even so, this little reader and the SD version, (priced at around £12) both represent a relatively inexpensive upgrade to USB2.0 - providing your PC supports the standard.
