New Mac HD Space

[Shane Ross]

Yes…that is the talk. Since no one has one we can’t say for sure.

BUT…you’d have to install your OS on an external drive and boot off that as you can have your OS on the internals if you want to use all of them for a RAID, and you’d need to stripe all of them if you wanted to do uncompressed HD work.

OR…you can get a Parallel ATA drive and install it in the second Optical bay. That is the talk that is going around in my circles.

I was going to ask about this, Shane. On my old G4 DP, there was space for 4 internal drives, which we RAIDed, and the
boot drive was external FW400. You could put the boot drive in an empty optical bay, but the buss was
pretty slow. I’m guessing that the optical buss on the MacPro is much faster, any info on that?
When the new 750g drives get the bugs worked out, a 3TB internal SATAII RAID will look pretty sweet.

I just found out. This diagram of the MacPro architecture hsows it to be an ATA100 bus.

From Blackmagics press release

‘Blackmagic Design’s testing has shown, that when the new Apple Mac Pro is populated with 3 x 500 MB SATA disks internally mounted and striped with RAID 0 configuration, approximately 170 MB/sec disk array performance was achieved. This allows customers to build lower cost HD disk arrays for simple capture and playback tasks. For higher performance editing solutions, Blackmagic Design’s testing has shown Apple’s Xserve RAID works well as a high performance uncompressed HDTV disk array. ‘

I guess It would be nice to put the system disk in the spare optical slot then have a 4 internal way raid
