Nice thread guys… very enlightening. I like your approach Walter…

[Chris Tomberlin] “Plus, there are some real problems with the 10 bit codec right now. Do search in the After Effects and Blackmagic forums and you’ll see what I mean…”
What did they change… it was working fine before?

Clearly something that needs addressing. I’ve used lots of stills in the past, and generally have the still cache at around 25%, but I’ve never seen it do this. I’ve seen it take forever to open a project with many stills (in the past), but not refuse to open…
Thanks for sharing this…

[jaser] “thanks mitch…obviously an internal sata would be my first choice. but i also need an external option. you mentioned you would never use 2 drives. so what would you recommend for a one drive external sata? thanks again mitch.”
Actually, I was speaking of external solutions. I wouldn’t bother with a single external SATA drive. It won’t solve your problem.
You can try a two drive external, but I’d get the 4-port PCI card so you can add two more drives in the future, without having to scrap the PCI card. I recommend a four drive external SATA array.

Actually, the people I know who have tried DVCProHD off of a FW HD have had nothing but trouble. I realize some people ythink it’s working, but I remain unconvinced.
Of course the real question is: why do people spend so much time trying to make this work?

[jaser] “what do you recommend in replacement(sata) of a g-raid firewire800(similar as you suggested)? thanks…”
Well first, I wouldn’t use anything with two drives, but if I did I’d use two SATA drives in a single external case. Why? Because they will be faster, and I know it’s only a matter of time until you add two more drives anyway. Realtime is one of those things where you don’t realize what you’re missing until you see somebody with a lot more.
SATA clearly kicks in at three drives and higher (four IMO). I’d go with four SATA drives in two Firmtek cases with a Firmtek 4-port SATA card. A 1Tb will run around $1,100 total (which is less than the new 1Tb G-RAID.
People who have watched uncompressed 10bit over here realize that there aren’t getting any realtime by comparison. Like Walter alluded to in his post, people are going too minimal in the disk sub-systems and they aren’t aware of how it’s affecting the performance of their FCP system. We’re building race cars here… just having the best engine won’t get you the trophy. Everything… the computer, the video card, the amount or RAM, the disk array… they all count.

[CharlieX] “Is the drive brand new? Have you tried say, 10bit Uncompressed media on it? What version OS/FCP are you running? Can Quicktime Player play the DVVPROHD media without hiccups?
That’s a pretty good drive. I have one myself that gets used daily, and for 10bit Uncompressed it’s been a far more economical solution than trying to add more storage to my SCSI JBOB.”
I can’t agree with this advice. The G-RAID is marginal (in my mind unnacceptable) for 10 bit uncompressed. Since I’ve been doing 10 bit through SDI longer than most, I feel qualified to say that.
As far as economical, it simply isn’t the best choice. A SATA array is much better and similarly priced. I will never understand the attraction of these G-RAIDs. I’m not saying it’s a bad product… it’s just nothing special and better can be had for the same price.

[Walter Biscardi] “FW400 should not be used for anything but regular DV, period. And even there, you’re giving up a lot of RT performance with FCP.”
I’m inclined to agree… since we’re talking about hard drives.
Of course I should allow for the fact that our Aja Io does a great job of 25mb/sec uncompressed SDI work, all over the FW400 bus… but that’s not a case of hard drives. It seems like I’ve been noticing that of late many people (not you Walter) are starting to allow the data rate and the hard drive throughput rate to be interchanged in conversation, when they are two entirely different things. Or, maybe I’m wrong…

[gary adcock] “I cannot believe the number of people here wanting to save $500. on hard drive to use, when they spend that much or more to rent a 1200a deck for a single day or $1200+ to rent a camera. “
I’m going to have to agree here. What surprises me is the flood of people who seem to want to go with minimum config’s on arrays all of a sudden. While some people may have gotten a two drive system to work, I ask why? Why not get a faster four drive system? The new 1TB G-raid cost more than my four drive 1 TB SATA array, and my SATA array runs circles around the G-raid.

[CharlieX] “The 1500A exhibits the same problems as the AJA Io. It must have the whole FW bus to itself. Otherwise during playback there will be random black frames going to your NTSC.”
Well that’s ugly, as I do it all the time with a 1500 (not the a model). I’ve had three firewire drives connected as well as the 1500 and never had any issues…
