Would RAID work ? Any experiences ? |

Hi there, I just found another harddisk of my current one, so I thought about reinstalling OSX (which works fine currently) on a RAID-0 stripeset with two IBM DCAS 4GB disks, using the built-in OSX software RAID facility during installation. Does anybody have any positive/negative experience with that? Has someone managed to do that successfully yet ? Thanks, Ebbi (9600 w/Sonnet G4 400) |

I have seen a doubling of performance for a pair of UW drives hooked to my ExpressPCI PSC, but it seemed kind of fragile too... I eventually scrapped it. I wouldn't bother trying unless you have a true matched set of drives. Although several softwares advertise that they can cross media stripe, this seems sketchy to me. Marty |

I have created a stripe via disk utility (OSX.2.6) and Softraid beta and I saw no increase in performance. I have a 8500 with 2 36g 10K ST336706LW drives attached to an Initio U2W card. Tim |

I think worldalex is speaking of the XPF boot extensions, that is a VERY good point..... |

There is also the concern that formatting the drives during the install could erase the installer, so another drive would be necessary. |

Clarifying...... OS9 won't SEE the disks, they will be fine if you go back to X |

Yes, it is scary how easy it is, I did it with 2 ibm ultrastar 18 gigers just to test. It worked great, but I had to split up the RAID to yank a drive for another machine. I did it AFTER jag was installed and running, just using the disk utility in the software. Might be best to clone your install to another drive, make the raid in osx, then clone X over to the raid. You could do it from the install, but I have never made a RAID at that point, so no info on that, the prospsct makes me nervous.... ;-) Remember, you will loose those disks to OS 9 if you need to boot into it!! |
