Hello all,

 

Looking to get some feedback on the potential workability of this upgrade for my early 2008 MacPro (16GB RAM running OSX 10.6.7). I work in video post production so I need speed though not necessarily a lot of space.

 

Here is what I'm thinking:

 

BOOT DRIVE: Internal 240GB SSD (OWC SATA3)

- Power via optical bay via adapter cable

- Data via PCIe SATA3 card and cable running out the back

 

Was thinking of this card:

as it seems to be the same as this but cheaper:

SCRATCH DRIVE: 2x 300GB Velociraptor SATA2 in software RAID 0 in drive bays 1+2

 

SCRATCH DRIVE/PROJECT DRIVE: 2x 1TB 7200 SATA2 drives in RADI 0 in drive bays 3+4

 

BACKUP/STORAGE DRIVES:  2x large 5900 drives connected via external Icy Dock stations that connect to 2 internal eSATA ports on logic board via extension cables. Possibly an extra SATA drive in the optical bay too via SATA-IDE converter. I have an external firewire optical drive.

 

Questions:

 

- I am using a flashed PC graphics card: 1GB ATI Radeon HD 4870 which takes up so much space I only have room to use the two top x4 PCI slots. WIll these slots be able to fully support the PCIe SATA3 card for the SATA3 SSD?

- Will the SSD be bootable with the PCIe card linked above? It appears to be the same one that OWC sells but cheaper?

- Is the speed increase with the PCI card/SATA3 SSD really worth all the fuss or should I just get a SATA2 SSD? I've read on barefeats that SATA3 SSDs can actually be slower than SATA2 SSDs when not in a SATA3 connection

- Any bottlenecks you can see for limiting my speeds? Will the total transfers max out at 1gbps and do you think this will push that?

 

Many thanks for your time!
