This is obviously way too much info... but I had 2 cups of Starbucks....
I will send pics of one my MDDs with the SSDs when I am at work tomorrow... My config is the same on all 3 MDDS... I have the OWC on the Ultra 100 IDE controller (in line with heat sink) by itself... The SSD has main OS... all apps and all samples for Halion, Kompakt, LM4 MkII and Battery kits... also all virtual instruments (like Virtual Guitar) so they load extremely fast.... also my current 1 or 2 audio projects, It's Partitioned into "Mac OS" and "Audio-SSD"
On the Ultra 66 (Under optical cage) I keep (2) 500 GB drives with 3 partitions each...
Drive 1: Audio 1, Library (All Software Installs), Samples (all the sample I own for OS 9) and
Drive 2: Audio 2 (Archives and Backups), Images (CD and DVD Image Files), Video (Video and Pics)..
At least 1 partition on every drive is bootable (with a different theme to remember what partition is booted at the time)...
Every MDD also has (1) UAD-1, (1) PowereCore PCI, (1) M-Audio 2496
I do a similar setup on (2) QS 933 live recording macs... A single OWC SSD on the Main Controller and a 500 GB (where the zip would go under the Optical Drive) The SSD has an OS with apps partition and an "Audio-SSD" Partition for the current live recording project... the 500 has old recording projects split up on 3 partitions for clients.... each QS G4 is mounted sideways in a Road rack with Mac Marathon Ears and has a PCI 424 Motu card and (3) 1224 MOTU interfaces
