Updated: After Snow Leopard
Updated to Snow Leopard and had a huge performance hit. Moreover, sleep no longer functioned *at all*. Since this is an app only machine, image restoration is pretty simple and straightforward. Wiped disks as close to as new as possible ( erased the current raid, reformatted, recreated the RAID 0 with a 64k stripe ). I will need to recalibrate the battery, but reset PRAM etc should have this machine pretty close (firmware updates aside).
Running 10.5.8 - RAID 0 with dual X25-M in a MBu 2.0 with the optibay swapped out. Status: No issues
Running 10.6.1 - RAID 0 updated from 10.5.8. Sleep does not function.
Running 10.6.1 - RAID 0 created from scratch. Sleep does not function.
Restored to 10.5.8 and am back to running at monster speed. Yeah, no SL for me. Perhaps I'll retest on 10.6.2 if so inclined.
Only app on this image is Firefox and the default OS X install apps. Customized without add ons (no X11).
I'll post updates in hopes someone else is having these issues with SL.
