Hello,

I am getting disoriented by all those new, cheap USB-hosted SD card readers
popping out every month with astonishing specs (like 480MB/s) while I can
read so many disappointed testimonials.

I am ready to buy a IOGEAR single-slot reader (ref. GFR202SDW6) but I am
wondering if it works with 4GD SD cards. I asked IOGEAR support folks by
e-mail but they remain silent sofar.
Already tried that combination, anyone ?
Also, if you succeeded using 4GB cards with any other USB-key-like SD
reader, please let me know which brand & model (both card and reader).

And, by the way, if you have any clue about MP3 players that use both SD
cards as storage and USB as a link to a host, I would appreciate getting any
information for those that can handle 4 GB cards too.

I just cannot believe there are so few people looking for accurate specs
like me.

Few use SD cards with MP3 players.

They're mainly used in cameras, try asking in one of those groups.

More like 480Mb/s.

And look what good that does to you.
Can't even get the specs right once you get them.

Hehe, that would be 480Mb/s, not 480MB/s. And that is the maximum
theoretical interface bandwidth of USB2.0. The card will be much slower
and if the card is really, really fast, I would be surprised if you
get much more than 15MB/s (=120Mb/s) from the card. Of course the
reader cannot deliver data faster than the card....

A good indicator that you should not buy anything from them.

The problem is rather that people with no knowledge or semi-knowledge
tend to believe what marketing tells them. On the other hand, marketing
tends to put the highest number available on it.

Example: Many people see marketing claimes of 3MB/s for SATA II drives.
First SATAII supports 3Mb/s (thats 12.5% of 3MB/s). Second, that is
what the interface supports, not the drive. In practice you get something
like 60MB/s at the beginning of the drive and 30MB/s at its end.
But if marketing would put these numbers on the drive, people would
buy the "faster ones".
