I had two pairs of 7200 rpm drives that are striped one and I get great performance. It should be even better with the Raptors.

One thing that I read (I think on AMUG.com or Barefeats.com) is that as your drives fill up your throughput goes down (at least in striped RAID setups) so be sure to leave plenty of room on 'em

OK so I've done a lot of reading about drives, streaming etc as I'm about to get one of the new MacPros. My head is spinning like a 10,000 RPM external eSATA Raptor JBOD concatenated set of disks (or was that RAID 6?). Anyhow I'm going with basically the same setup as Gabe S's on page 1 of this thread..internal drive(320), 500GB 7200 for projects, and 2 x 150 Raptors for my orchestral library.I have EWQLSO Gold, and just bought Platinum as well. I'd like to ask Frodo, as you seem to have similar libraries to me, how you have them setup over your drives.
I'm also still tossing up whether to RAID-0 the Raptors, or JBOD them. I understand the pitfalls of both, but how different are the performance positives?

Thx

Very true, RA. And performance varies depending upon the type of RAID config is being used. If one is taking advantage of the "R" in RAID, then there are certain "redundancies" that are essential to guard against loss of data.

Yeah, one of my RAIDS took a little nap this afternoon and it was pretty exciting : ) Fortunately I just had to restart, but it can be scary. I've been backing them up onto inexpensive ATA Drives (lots of 'em) ...

I've seen Raptors in numerous studios I've worked in and have never had a problem. Ironically, one just went bad on my personal system. First time I've ever seen one of these drives go South.
WD didn't have any more 150 GB Raptors in stock so they sent me the newest 160 GB Raptor to replace the bad one. The specs are all identical except for the fact that the new one has 10 GB more capacity than the previous model.
I have one for my System drive and one for my Audio drive. My original System drive (came with my Mac) is being used as my BFD drive.
At the moment, things are coming along swimmingly.
I'm not sure if this helps but, I thought I'd post anyway.

Ah, I didn't realize that WD was slowly upping the drive capacity on the Raptors. Nice to see.

I guess pretty soon we're going to have to start a 15K RPM thread : )

Frodo thank you for your reply.


Regarding a SATA PCI card:

What if one has a LOT of PCI cards (an expansion chassis with 7 cards)?

Do you know how much headroom the PCI busses have on a G5 dual 2.5?
Are the PCI busses really seperate, or do they compete for bandwidth at some bottleneck somewhere?

Thanks again.

Hello,

I am still interess about External hardrives.

So,
I have a G5 Dual 1.8 With X.3.9, 3.5G Ram, UAD1 Studio Pack
on the Slot 4 (64B,133MHz), DP4.61.

I would like to put The PCIx Card SeriTek/1eVE4
on the slot 3 (64B 100MHz) connect to 3 HDs.

One of the HD I would like to install Tiger X.4.10 and also all my aplications (DP4.61, MachV , Styllus.....).
Is it Possible?????
For to have the possibility to boot on Tiger.

And the two others HDs for the VIs.

Some body Use this card????

No conflits with the UAD1????

Thanks for your reply

I was just recommending the Sonnet card. I know they make a PCIx also, but I don't think it's bootable.

Why do you want to boot from your external drive?

Yikes-- not sure about the state of expansion chassis with pros and cons (don't have one myself), but I think HopiWay has such a setup and got things working pretty well.

****
Specs for G5 Dual 2.5 PCI:

One 64-bit PCIx @133 MHz (independent bus)
Two 64-bit PCIx @100 MHz (shared bus)

Even on the shared bus, the bandwidth is going to be a bit better than, say, firewire which tops out at 33Mhz. The tricky part is understanding what role bandwidth and bus speed play in the drama of streaming, and then understanding how this in turn plays with/against hard drive seek/transfer times as per settings made in the host app's and plugin's work priorities. It gets complicated and is something I'd consider to be more project-specific.

What is the best solution for a G5 dual 1.8 with 8 slots ram.
For an external HDs systeme.

Card PCIx Firewire 800???
Card PCIx ESATA II???
On the slot 3 (64B,100MHz).

Because I have my UAD1 on the slot 4 (64B,133MHz)

For this moment I have two internal HDs
One for the system X.3.9
And the other for Audio and the VIs.

I would like to install on one of the HD Tiger
For to have the possibility to boot on Tiger
And the others HD for the VIs

I try to find the right solution and also work properly with my system.

Sorry if I insist but I dont want to mde a mistake

Thanks
