I have investicated using ultra wide SCSI 15k rpm drives but has anyone tested 10K RPM SATA drives?

Richard where you testing SATA or SCSI 10K's?

the tests are being done.

buy a couple and test them for yourself
the raptors certainly help.

or just buy one - put it into the internal slot, and dont put the os on it.

Are you talking about SATA or SCSI?

buy a sata raptor drive. 10000rpm.
compare it with the existing drive. its much better.

scsi works a little better. using 10000rpm and 15000rpm atlas iv drives, i dont see much of a performance difference with dv codecs in catalyst.

the atlas 10k iv 140gb drive has double the capacity of a single raptor.

I have just ordered per machine:

2 73GB Western Digital 10K RPM Drives
1 G5 jam
1 ATI Radion 9800 Pro
1 USB card (with internal USB's)
1 BlackMagic Decklink Extreme video input card

and a killer case that I am designing.

The scsi option was way too expensive for only a little bit of improvement. External racks an all. FYI the Glyph rack mount is only a single channel SCSI thus it prevents you from taking advantage of both channels on the ATTO UL4D card. The Storcase Data Silo does provide support for dual channel. http://www.storcase.com/DataSilo/ds320.asp

Hi,

I´ve installed an G5 with 2xraptors (73Gb) with Apples own RAID tool,
their in RAID0, It works very very well..

mail me if you have any questions:

works even better if you put the system on a different disc.

( it does make a difference with accuracy of playback over long segments on 4 layers - I know martin had a few issues with this in norway )

it more important in ntsc 30hz systems which have to work faster.
we only have to work at 25hz in europe - but an issue with dl1's makes them work better at 30hz too.

The system can interupt playback when it does house keeping or any other work - that involves disc access, or virtual memory.

We tested this and found out that we did not get any more performance on a raid than on 1 std disk and 1 sata. os on one and cat on the other.
besides, when one disk fucks up, you can keep a backup on the other, so you can (hopefully) still do the show. As for the playback sync problem, the use layer function saved the day.

keeping the os separate gives slightly better performance over the long term - minutes -

i dont think using an internal raid is good either. if one disc goes down - you loose everything.

there is no difference between using 1 or 2 raptors - unless you need the extra gb capacity - or unless you want to play back uncompressed movies.
