    I currently have a Stripped RAID setup with dual 160GB. However, I am looking into getting bigger internal HDs.

    Do you know if there is a limit for the size of the HDs for my PowerMac G5? Or is this determined by the Operating System?

    PowerMac G5 PPC Dual 1.8 GHz, 6 GB RAM
    Mac OS X 10.4.11 (looking to upgrade to 10.5 soon)

    Thanks!

    The only size limit was pre-Quicksilver G4s, when the controllers didn't have 48-bit addressing. So in other words -- no, there is no size limit for your computer or any Power Mac/Mac Pro since 2002.

    With Leopard I know for sure that you can SW RAID0 two 2TB drives which would give you a total capacity ceiling of 4 TB with current drive technology. I don't remember if Tiger had the SW RAID0 facility in disk utility. I only switched 12 months ago.

    Well, well, I think I will be OK with that limit. :D

    Yes. Tiger supports SW RAID0. That's what I am using now with my dual 160GB.

    Now that we are looking at Terabytes for storage. Is there any recommendation about RAID technology and partitioning setup to get the best performance and reliability?

    For instance, is it better to have a single small HD (e.g., 160 GB) as the main boot disk with the OS and all the applications, and a second large HD (e.g., 1TB or more) for data?

    Or is it better to have a RAID0 with two large HDs (e.g., 1TB or 2TB) and put everything in there?

    Thanks!

    Aside from the valid concerns over the older G4, I partially blame :apple: for so much confusion over drive limits. I know it doesn't necessarily apply here, but how many of you have read posts wondering if out-of-date promotional materials for Macs, stating "Up to X units of HDD space!:eek:", leaving some folks to wonder if it's a restriction?

    Your best option is raid0 on two big disks. You could refine that by splitting the top ten % off both drives and make two RAID0 arrays. One small would hold OS and apps. The big one would hold the data you want to store like music and video.
