My brother has a clamshell 366 iBook with a 60 GB 4,200 RPM HD now as a single partition with 10.3.9 & 9.2.2.
He rarely uses 9.2.2, but does still use it regularly, so it can't be OS X only.
He recently has tried to play so video's (DVD or MOV format) and has a slight stuttering which may be the slow CPU or HD?
It's both, most likely, coupled with the anemic video chipset in this system.
I will be upgrading his System soon and I'm thinking about partition schemes.
I thought a small 2 GB for OS 9.2.2, then a large 48 GB for OS X, and then a 5 GB for video or scratch disk.
The questions are:
If the final 5 GB partition is on the outer sectors will these have faster access than inner sectors?
Not noticeably. This is a 2.5" disk; the actual disks are around 2" in diameter or less, rotational speed & buffer has a vastly greater impact on data transfer rate.
Could I striped RAID the 48 GB by making two 24 GB and use Disk Utility RAID to get faster access? I've never heard of RAID on a single HD, will this work and actually gain speed?
No. RAID requires separate physical drive controller interfaces; hence separate physical drives.
The speed gains is because data access across interfaces can proceed in parallel with data coming from both drives simultaneously.
I wouldn't partition the thing at all, personally, unless you're doing video editing and need to have a large scratch partition you can routinely reformat.
There's no need for separate OS 9 and OSX partitions, unless you want more than one OS 9 system folder, say one for Classic us and one for native OS 9 booting.
