Hello Mac Rumours this will be my first post, I have learned many things from this forum and I am grateful for all the help people have given in the past. In the next few months I will be looking to purchase a new computer. At the moment I use a G4 mac, mirror drive dual 1.25ghz 2 gig of ram for music production. I would say I am freelance music composer but at the moment it is just a serious hobby. With this new computer I am looking to get I also want to do 3D level design using hammer and possibly other 3D engines like the unreal engine and also use the 3D program Soft-Image to create 3D objects and in the end make my own levels and put my own music to the levels, in the end my own game but that is far away. I have a few questions though before I make a decision on this new computer. I understand that the Mac pros have 4 drive bays, the way I would like to configure this computer is. Drive bay 1- 1-2 Terabytes for - work in progress and recording audio in projects Drive bay 2- 4 SSDs and may expand in future to 8x256 SSD using a raid card controller this will be for intensive orchestral sample librarys for streaming/reading Can I fit 4 SSDs in a single bay? How many SSDs can one fit in a single bay? Drive bay 3- 512 SSD for streaming more samples Drive bay 4-A Hard drive for 3D level design and finished work. Though perhaps for finished work I may use external hard drives. In the optical bay a 60-80 gig SSD for the operating system and the applications I use. I would like this separate from rest of the Mac. I seem to hear only good things about doing it this way. I guess when the time comes I will need to ask how to move the OS to the SSD but that can wait. Is this setup for the hard drives possible and sensible? If one constantly writes and re-writes on SSD's does this degrade the SSD? As I am streaming or reading from the drives I am not sure this concerns me as much but how much degradation will occur with constant writing to the drives? RAID CARD- What raid card does one suggest there are so many I really am confused with all the options This thread at Mac Rumours gives some options http://forums.macrumors.com/showthread.php?t=973467 I saw suggested somewhere that the Rocket RAID SATA III 6Gb/s. Though after reading what some customers have had happened and gone through with the drivers I am uncertain about this company What Raid Card does one suggest a Sata 3 at 6Gb/s for 4-8 SSDs that works on a mac pro? Some in the forum have suggested Areca the company but there seems to be so many, even from just that company and the cards are more expensive than the Rocket raid card like Areca card ARC-1880ix-12 PCIe 2.0 SAS Controller. Some help in finding the right raid card, there just seems to be so many I am not really sure which one is the right one for my needs I guess a Raid card with maximum read speeds on the SSDs does this make sense? Advice is needed as I am new to raid cards I am new to raid in general let alone the SSD drives. I have heard one does not need a raid card in RAID 0 is this true? I am not sure about all the levels of RAID 0-6. For streaming I guess all the drives need to work as 1 but if one fails I would not want the rest of the drives to be destroyed. I am not sure what raid I would need as nothing will be saved on the drives, only the samples for reading. I am looking at the maker of Crucial SSDs simply because of the read speeds not the write speeds. If I do set up a raid card with 4 or even 8 SSDs the next step is an enclosure for them are there any suggestions for enclosures I have seen people suggest ICY DOCK enclosures or an OWC multi-mount. With the enclosures and 4 to 8-SSDs linked to a raid card in drive bay 2 do I next need a tray to hold them in the bay or is the enclosure or mounts sufficient? I am also considering as an option in getting a Pcie sound card so with the graphics card a raid card and sound card I should have enough room as I understand there is 4 Pcie slots, is this correct? Lastly I have dual monitor screens set up with my G4 is it possible to use the dual link display from apple that I already own with the new mac pro to link 2 screens? I think the new mac pros use the Digital Visual Interface- DVI connection is the connection the same as the G4 screens? I dont plan on using the computer for playing games and I would like it to last for a very long time as long as the G4 has lasted. I may have more questions if anyone can help thanks. Thank you and all the best.
