FW 800

[Shane Ross]

Depends on the drive. I have two G-Raids that are not only firewire 800, but TWO drives RAIDED together via hardware, so they are pretty darn fast. You can do 2-3 streams of uncompressed 8-bit SD and one stream of uncompressed 10-bit SD…but that won’t be reliable.

Look into SATA RAIDS as well.

[meeroo] “Can I use external Firewire 800 disc for working with 8-bit uncompressed video? I know it’s fast enough for DV, but is it for uncompressed?”

Both G-RAID’s and LaCie’s Big Disk Extreme FW800 units are fast enough for 8bit uncompressed. You can read my review of both in the Features section of the Cow.

SATA is now a viable option as well for 8bit Uncompressed.

shane, can you explain this? How do you have these drives raided together, I’m in the same situation as meeroo.
[Shane Ross] ” I have two G-Raids that are not only firewire 800, but TWO drives RAIDED together via hardware,”

Also, you said that the drives won’t be reliable yet Walter says that the FW 800 from G-Tech and Lacie drives are fast enough. I’m a little confused.
(i will read Walter’s article now while I wait on hopefully a reply)

Thanks for the help and the knowledge.

[walter biscardi] “SATA is now a viable option as well for 8bit Uncompressed.”

Not only viable, but better…

[David Roth weiss]

Shane is saying that 10-bit uncompressed is pushing the limits of any 2-drive raid.

With two drives arrays, performance is about identical. We run both FW 800 RAIDs here along with SATA RAIDs. With two drive units, speeds are almost the same.

Stripe two G-RAID’s together and you get almost the same speed as our 4 drive LaCie SATA array.

So I don’t think one is better than the other. They both serve the end user well and it’s really up to the end user as to which fits better with their budget and workflow.

Personally, i’d probably go with the FW800 drives for moving back and forth between two systems since you don’t need any additional cards to use FW800 with Macs.

The GRaid is 2 drives in one case, and they’re hardware striped as RAID0. There’s also the
new GDriveQ, which is USB2, FW400 and 800, and e-SATA, all in one case. The company says
it (and the regular GSATA) deliver a lot more speed than the FW800 GRAID.

how about for dvcprohd and dvcpro50? firewire800 or sata? which will give me more realtime layers? is fibre channel overkill for dvcprohd/50?

[Ed Dooley]

There are very few reasons to use FW anymore for anything related to video capture. You can get desktop or portable SATA solutions,
and SATA is faster, therefore more RT, drive prices are comparable to ATA drives.
Look for throughput specs or posts, they’re everywhere. A 2 drive FW RAID won’t be fast enough for DVCProHD, but will
be for DVCPro50, except you won’t get multiple layers. A 4 or 5 drive SATA RAID is the most economical fast setup.
FC is overkill for DVCProHD/50, if there is any such thing as overkill. FC will be appreciated if you get that UC HD project.

I wholeheartedly disagree. I am using 2 G-Raids…NOT raided together, just individual drives with their internal 2 drive raid, for DVCPRO HD and they work just fine. I get 3 realtime streams and lots of realtime effects. G-Raids seem built for DVCPRO HD. Great portable option.

But yes, if you can, a SATA Raid is the best way to go. But G-Raids are just fine.
