Mac Pro Raid Card Config

[Shane Ross]

[peter tours] “In disc utility I see both the system drive and the “raid” as separate “drives” but I am wondering if by using the raid card I am actually imitating a config like having just one drive for apps and media because it’s all coming thru the card?? “

If the Disk Utility sees them as separate, then they are separate. If the system drive is not part of the Raid, it is separate.

[peter tours] “I am considering trying the system drive in an optical bay. Does anyone have an opinion on this?”

That’s where mine is. Leaving all 4 bays for other drives. But I don’t have the RAID card.

[peter tours] “It sure seems like my system is very “boggy” but I really have no benchmark – except my old Media 100 system ran a lot smoother back in the day…. “

Run the AJA SPEED TEST on the RAID. Free at AJA.com. And how full is the raid? They start bogging down at 80% full.

I had an interesting situation that may or may not be applicable in this case. I had a raid card, and a raid 0 (backed up as well) and I swapped out my video card and my raid was gone. I fiddled with it for a long time and came to terms that I had lost data. I had one last thought, pulled out my raid card and the raid was back online. Turned out that I had set up a software raid and apparently when I swapped out the video card it initialized the raid card? It was bizarre, but I did have a raid card in my machine with a software raid running.

Shane – I have a Kona LHe so I already had the utility. Here are the results using DVCPRO HD 720p60 frame size:

File Size Sweep
MB MB/sec

• Read Write
• 128.0 204.3 203.4
• 256.0 199.3 165.1
• 512.0 183.5 166.4
• 1024.0 192.5 176.8
• 2048.0 193.3 181.0
• 4096.0 196.1 174.0
• 8192.0 196.6 178.0
• 16384.0 197.3 177.9

I am having trouble formatting it for the cow. but the first column is file size, then next to it read speed followed by write speed.

Clearly better than 100mb/s required for DVCPRO HD but nowhere near 300mb/s rating – but certainly more than adequate.
