Memory Needed?

yes you can stripe two SATA drives together in a RAID using Apple Disk Utility. You can actually stripe 4 SATA drives using wiebetech's G5 Jam...but it doesn't help you run multiple movies any more smoothly. It's more of a seek time issue, how fast the read/write head can whip around reading bits of 3 or 4 movies a bit at a time. Imagine a record player's needle jumping around trying to play 1 snippet of each of 4 songs before it had to go read a snippet of one of the other songs....

then you get an idea of what your hard drive is doing.

and 2 drives can be slower than 1.
so you have to be careful.
because data has to be read off both drives.

Is it conceivable that Catalyst could be configured for each layer to use a separate drive?

If you configured Catalyst to read each layer from a sep. drive you would need 4 times the storage space and have to maintain 4 copies of the same material. Sounds like a pain to me.

No.

this just doesnt work - unfortunately. this part of the mac is not multithreaded - quicktime only does one thing at once.

and the slowest drive in the system drags performance down.

if you put content on an internal drive, and on a scsi drive at the same time.
the slowest drive will pull things down.

Interesting.

i wish it worked like this. but it doesnt.

having more drives, may help you play back uncompressed movies.

So if I did that I would have to have some kind of external HD enclosure because if I am thinking correctly there is only room for 2 internaly

wiebetech came up with this thing....
the G5 jam.

I have been trying to find a rackmount 1u scsi or serial ata solution.
havent found one yet.
There are larger rackmount cases.
granite digital have 4u scsi enclosures. as do others.
