Ok
Im sorry for the confusion let me start over..I have been a producer for over ten years with major label credits..I already have all the apps and plugins on my g5..I need specific information on how and why should i zero my new drives..and the configuration info on 1 drive for my boot drive 1 drive for samples and audio and 1 drive for just apps..could someone please explain it to me like I was a four year old..and a hearty thank you to everyone who posted so far....
1. Zero Format new harddrives: This is in general recommended for any harddrive you purchase/get and built into your machine or external case. It means that each bit on the HD will be read and written once. In case this bit is defunct - for whatever reason - the drives firmware will mark it as unusable and it is no longer possible to write on it. This basically means better data integrity, because the HD can write on a defunct bit without any error message at all - but it cannot read from it anymore. Your data then will be lost.
How to do it: Run "Disk Utility", choose the HD you want to format, choose "Erase" and there the button "Options": There you find the "zero write".
2. Separate Boot drive: Your system and application software is there to be loaded from time to time. Also the system uses caching files / virtual memory on this harddrive (you can change the location, but that´s not necessary for your needs) to maximize memory efficiency in case your RAM memory is not enough. So it´s not about fast boot times, but about access to system and application files. Think about it: You record on that drive and the harddrive writes audio data to it. At the same time the system must access the virtual memory file and maybe an application routine must be reloaded, too: The HD read/write head jumps around like a goose on loose. Let´s say you record several audio streams at one, in high quality 96khz or even 192khz: You will very likely get pops and crackles embedde dinto the audio, which means: There stream was broken while the HD accessed other files interim.
How to do it: Have a separate boot drive, where you put your system (OSX), all your applications and your user data (Mail, web browsing etc, you name it). Have a dedicated audio recording drive (running Logic this means your project files) and another dedicated audio samples drive (Apple loops, Reason libraries etc.).
3. Applications and Plug ins: Check carefully, whether all of those installed on your Powermac G5 at the moment are compatible with Intel processors. Many audio plugins won´t run natively on Intel, or let´s be frank: In many cases you are forced to repurchase Intel compatible versions. Same goes for applications, although here regarding Logic, pro Tools or Cubase, you are good to go with versions from the last three years (footnote: all OSX recording software is 32bit based at the moment - but you won´t really need 64bit rigt now, as Logic, e.g., lets dedicated PlugIns run in 64bit mode, so they can access memory beyond the 4GB 32bit limit).
4. Audio Hardware (capture cards, DSP etc.): Here you need to check, first of all, whether they are PCI express based: Your Mac Pro does NOT have any PCI slots. Second, you need to check, whether Intel AND OSX Leopard/10.5 compatible drivers are around. If none of this is true for your owned hardware, you are ready to get new one. In this case do intensely think about what you really need/want, then get it accordingly.
5. Your Mac Pro: It is a killer machine, which will make you happy for the next five years, believe me. Now my first recommendations limited to harddrive setup, as I don´t know much more at the moment - for your setup (in brackets you see the "I have the money"):
a) Get a 640GB SATA boot drive (or an Intel X25 SSD)
b) Get several 1TB drives (1,5 or 2TB) and fill your internal bays: one for recording, one for your audio library, one or two for backup and additional stuff; all depending on your workload, which you haven´t told us yet. You may want to get an external drive (firewire based), too.
c) DON´T use RAID at all- you don´t need it for 99,99% of audio workloads. You can, but you musn´t use partitions to organize - using clean folder structures is sufficient.
d) You probably know best: choose 24Bit/96khz recording depths - that´s more than enough.
