The PCMCIA <-> SD conversion isn't purely mechanic AFAIK (unlike with PCMCIA
<-> CF, which is just a simple, mechanical rewiring). This means it MIGHT
(if it indeed uses active electronics for conversion) consume more power
than the CF card in a PCMCIA slot.
Speed-wise, I've been using several SD cards in my PCMCIA <> SD converter;
I've never had any problems with speed (both reading and writing speed
around 1 Mbyte/s in my non-USB-2 Thinkpad a31p). That is, you won't run into
speed problems either.
