Elliot Posted June 26, 2006 Share Posted June 26, 2006 I continue with the speed saga. We have fined tuned the double Opteron Dual Core 285's. The machine is faster now. This afternoon I took apart the machine and took out the SATA 10,000 RPM drive with 4.6 ms seek time. Replaced it with a SCSI with 0 Raid (Stripping). I don't know if it is my imagination but the machine is definitely faster. Called Supermicro and talked with a a super tech support guy. He has some experience with the machines being built for video editing. He explained to me that a SCSI Raid is better than a SATA Raid. He explained to me that SCSI raid is like full duplex while a SATA is not. What this means is that a SCSI can write and read at the same time, while a SATA Raid can either write or read, but not at the same time. He explained to me that the software has to make use of this capability. He said this maybe the reason I see better timing know. Do you know if VIZ can write and read a the same time. Is it my imagination....? I am sure the machine is faster now... This is very confusing.... at the same time is very addicting to keep changing configurations to achieve better speed ratings. Have you experienced something similar...? Regards Elliot Link to comment Share on other sites More sharing options...
AJLynn Posted June 27, 2006 Share Posted June 27, 2006 I wrote a longer reply then accidentally deleted it. Long story. Short version of the reply: Viz is not hard disk intensive, it won't help much to switch disk configurations. Video editing software is - you could get a big speed boost in Premiere, After Effects, etc. - this is why people who use those a lot have SCSI RAIDs You could get a bigger boost by putting the SATA disk back in, in addition to the SCSI, and using one for source files and the other for output files.

Elliot Posted June 27, 2006 Author Share Posted June 27, 2006 Andrew That is what I did.... A SCSI Raid 0 for the programs and a SATA Raid Stripping for Data.... and the machine is definitely faster on Premier 2.0. Interesting.... I didn't know what you described.... Just by accident I discovered it.... I still think the machine is not as fast as I though it was going to be.... Thanks Elliot Link to comment Share on other sites More sharing options...
