From: Raymond <[EMAIL PROTECTED]>
I guess it depends ... if you're going to be using firewire on your libretto
(through a firewire PCMCIA card) then the point is moot - the bottleneck is
still there (you're still going through the PCMCIA interface).
Oh yeah... I'm talking about using one on the Libby. I recall people discussing it on the list here along with USB2, and just assumed people were getting faster transfer speeds.
That plus from
what I understand, the PCMCIA interface, at a hardware level, is at least as
fast, if not faster than your hard drive anyway.
But from what you were saying in your post (link to archives below), I was assuming that the on-board controllers on the firewire and USB2 cards would make a significant difference in transfer speeds through the PCMCIA port... no?
However if you're using another laptop then it's a different story. I have a
friend with a Dell notebook who gets faster transfer rates off a firewire hard
disk pack (7200rpm desktop hard disk) than off his laptop's internal hard disk,
for instance. Then again you'll need the really expensive high speed
professional CF cards to get that sorta speed anyway - if I'm not mistaken your
average run-of-the-mill CF card is slower than the PCMCIA interface to begin
with.
Actually, I have a 512MB microdive. From this quote on the other URL I referenced (below), the microdives can achieve some impressive transfer speeds:
"Also interesting is that the 1 GB IBM Microdrive has far greater throughput
than a standard Flash Memory card (certainly for writing) and that it's apparent
that even the latest digital cameras aren't able to write at these kinds of
speeds (though some Pro cameras can)."
