Hi Folks

I still haven't quite made it into the Mac World but have nearly settled on the following setup:

- Intel iMac 20"
- 2GB RAM
- Vantec NexStar2 Firewire enclosure + 300GB HDD
- PreSonus Firebox audio interface w/ 2x XLR inputs
- Edirol MA-15D monitors

I intended to use the external firewire HDD as my primary audio capture disk as this would leave the iMac HDD free for OS/application read/writes. Since I've never used an external Firewire HDD before, I'm unsure if it will be fast enough to capture my audio. I'm pretty sure it will be but I thought it best to check. I've only ever used PCs in the past and have always used the HDDs installed in the machine rather than external disks.

In fact, now I come to think of it, the iMac HDD is SATA. The NexStar2 HDD enclosure I was looking at uses PATA HDDs. Do you think I'd be better capturing directly to the internal HDD in the iMac or using the external for capture?

Your comments on this (and my proposed setup) would be really appreciated.

Cheers,
Fiddler.

Left the internal HD to the system/apps/virtual memory and swap audio to external, even with a fast internal drive you'll encounter conflicts one day when the heads of the drive will have too much to do on their hands. And it can happen fast.

Firewire is more efficient at real time streaming than USB, final. It won't show on a small number of tracks but in the dozens it will.

Choose a FW enclosure with an Oxford bridge to IDE/ATA drives, it's fast and reliable. also, only FW external drive will allow you to boot from them, not USB! Should you need it. I don't know the enclosure you write about, so I can't tell.

On the drive itself, given the size of audio file, 8 MB of cache will be as efficient as 16 MB (only needed for lots of small files), Seagate are more reliable on the long time (less return %).

Edirol monitors are just multimedia monitors, whatever they say, what's your intended budget?
