Advantage of FW CF Reader with Sandisk Ultra II?

Ok, so I have an XTI, and 3x4GB Ultra II CF Cards. I'm thinking of getting a CF reader for my Macbook Pro when I'm on the road and was wondering if there is any benefit to having a FW CF reader (vs. USB) when using Ultra II's.. Yes, I know the Extreme IV and such will fly (but I don't have the Extremes ). Just wondering if there's any advantage for the Ultra II.

I have used Ultra IIs and Extreme IIIs a while back, and I do remember a big increase between regular USB and Firewire. It was then I learned that -If I remember correctly- FireWire transfers at some 400mb/sec while USB 1.0 transferred at half that speed. Then USB 2.0 brought things to a relative matching speed.

I use FW for my MacbookPro and I see a real difference when compared to USB.

What I would love to see with my Ext IVs is the FW800 adapter -standard with the Macbooks-, but I have not found one yet for CF (under a zillion dollars, at least).

SHAZAM!!

WOOOOOOW !!!... Almost hit the buy button. Gotta check if what I have are UDMA cards, if so, they should meet the 800mbps transfer rate.

Thanks for sharing the link.

Not sure if you're really interested, but I noticed it for $40 @ Bestbuy online

Oh, another thing, looking on the Sandisk site, the Extreme IVs are UDMA Enabled..

Well thanks man, but what did you learn about your thread??...

Definitely did not mean to turn it around !!

Cheers

I learned there might be a difference with the Ultra II, but decided to go with the Lexar FW CF Reader because both my Macs have FW800. After I ordered, I also noticed the Sandisk FW Reader was $40 @ BB . But the Sandisk says 400/800 which I assume means that its 800 when connected to FW800 and 400 if connected to FW400 with a different cable?

Yep. Should require two different cables.
Cheers,

Not necessarily. If your computer has a 6 pin 400 connector, the 800 will connect, and just run at the slower speed.

If the reader you are referring to is the SanDisk Extreme FireWire Reader, it has a read/write speed of 40MB/s which puts it at the FW400 speed, not the FW800 speed, no matter which FW port you use.

Nope, both my "possible" machines have 9-pin FW800 slots. So there is an "opportunity".

Yes, that is exactly what I am referring to. I guess, normally, I would look at the "extraction" port to determine whether it was truly FW800 or FW400. But that may even be moot re: the sandisk model..

I will report back when I get the Lexar in.
