CANON has RAID
 

Dual Card Slots
The EOS-1Ds Mark II comes equipped with two card slots, one for CompactFlash (CF) and one for Secure Digital (SD) Memory cards. The camera can be set up to record images on either card for maximum storage capacity, or, for extra security, the same image can be recorded simultaneously on both cards.
That's bad ass!

yeah, that's super cool!

that's very cool :thumbsup

It's a great feature.

I don't see anything about raid... looks a lot more like JBOD than RAID, but even so it's really not jbod either, doesn't look like the cards are combined together in any which way, just looks like you can make the image write to both cards (if you are paranoid), or choose which card for it write to. Doesn't look like the cards are combined together in any which fashion to increase I/O abilities...

Heh, it's not really RAID, just a more basic redundancy. I've never used this feature as I have 4Gb CF cards, and I don't think it supports that size in SD...

A better of redundancy would be a tethered laptop or the wifi sender (assuming the pics are also saved onto the card in the camera)

Then again maybe you can write to CF, SD and the laptop! 3 way, baby!

Hopefully the next 1 series body has dual CF slots (or 2 X CF and 1 X SD), the Mark II has an SD slot because adding an extra CF slot would have required a body redesign.

Its nice. I have the 20d, and have a 6 gig microdrive, and sometimes wish that I could run two cards at the same time

I know it's not a real RAID. But accomplishes the same thing as a 2 disk mirror as far as redundancy.

Imagine if you were a wedding photographer and your single drive with the whole wedding got messed up at the end.

The WIFI thing is cool but is pretty much limited. Especially if you shoot allot outdoors.

Very cool feature

I keep looking at the date of this thread and expecting to see a 2002 since this feature has been around since the beginning of the 1D series...

Its a great camera, shoots awesome pictures, but gets very very heavy after shooting for awhile since its much larger than the 20d.

But the quality is second to none. And it eats memory cards like crazy, raw images are 90 megs each and if your shooting raw + jpeg at the same time your going to go through cards like crazy ( i know we do)

It was the MkII revision that introduced the extra slot, which would have been the end of 2004. I guess that's still old news though :)

Here's the original 1D with a single slot

damn canon is awesome!

CANON has RAID???

lol what are you smoking, 90 Mb for a CR2 image? Maybe on the Mark VIII model with 70 megapixels :Graucho

Most of mine are 15-20Mb each
