RAW video download with firewire 800
« on: June 17, 2014, 02:16:49 AM »
Hi, a straight question with a straight answer, I hope.

I'm looking to start out with RAW on my 5D mkii, and, before I start, am wondering if there's any reason that I shouldn't be able to transfer my files via a firwire 800 reader?

The 5Dii instructions in the forum are very explicit about using a USB 3.0 reader, but make no mention of firewire. I've searched the forum, but all I could find was some mention that Komputerbay recommend against it? I, however, am looking to use a new Transcend 1000x card with a Sandisk firewire 800 reader, since this is what I own.

It makes no sense to me that USB would be preferable to firewire, since I understand the latter to be the better, faster, more stable format?

So, is there a problem? Why do Komputerbay warn against it? And if not, should a note to that effect not be included in the Installation sticky?

Thanks.

The USB 3.0 issue had its start when large capacity KB cards starting with 64 gig and 128 gig with 1000x speeds got corrupted using USB 2.0 readers. Not much about the port themselves but the readers' circuitry. So for instance, if you use a usb 3 reader and plug it into a usb 2 port, the card would be safe, albeit, the transfer would be slow.
I have no info about fw readers and how they would handle the cards. If you have a non KB card, I'm guessing you'll probably be ok. Though don't take my word for it. ;)

Another thing to consider is if your FW reader is compatible with UDMA 7 specs.

The reader I have is the Sandisk Extreme Firewire 800 model. Which, trying to look up the specs online, is definitely UDMA compatible, but I don't know if UDMA 7? It's discontinued, and described in various places as 'legendary', for all that that counts.

Anyone have definitive field experience?

I have used the Sandisk Extreme FireWire800 model for ages, it works just fine.
