Replace LHe with Kona 3?

[Bob Zelin]

you have listed very important information. You have one RAID writing at 75mb/sec. You have an empty drive slot in your MAC that could hold one single SATA drive. A single new Segate 7200.10 SATA drive can do about 70mb/sec, and you report that your entire Infortrend RAID is only writing at this speed – SOMETHING IS WRONG WITH THAT RAID. I don’t know if it’s the ATTO driver, the RAID firmware, a defective drive, or your array is REALLY full and fragmanted, but SOMETHING IS WRONG, because it should perform faster than a single internal SATA drive (right now, simply run the test on your internal MAC boot drive, you will get about 58-60mb/sec – almost as fast as your entire RAID). You must resolve this issue.

Your card layout is fine, your Kramer black gen is fine. May I suggest buying a flashlight (I can’t see anything without one !).

I agree, it’s VITAL INFORMATION! The 2nd drive slot is occupied. Yes, I agree there’s an underlying issue with the RAID but that doesn’t account for the fact that with the Kona out and the Multibridge Pro PCIe card in and running, the nag felt like a racehorse. The LHe was the only thing that changed. Hmmm…

Thanks!

Expansion Slot Utility? On a G5? Isn’t that a Mac Pro thing?

Bob, he posted 75MB/s not 75Mb/s, thats’s an eightfold speed difference.
