I have no problem with this recommendation from Thomas. I've not used eSATA ut I expect it' performance it pretty good. I know nothing about the implementation team for that technology. There doesn't seem to be much happening with 1394 development these days. I use it because I have the drives and have industry experience, not because it's the best technology. Do some searching around on your own and figure out what works for you. An internal drive is goig to be the least painful from a Linux POV. If you have no need to move your sessions around to different locations then I wouldn't bother with any external drive based on my personal Linux experience. - Mark On 7/17/06, Thomas Ilnseher <illth@xxxxxx> wrote:

IF you buy a 1394 > adapter then try for 1394b instead of 1394a. really ... i would go for eSATA instead if 1394b. usb+eSATA external cases are cheaper than 1394b external cases, eSATA capable SATA controllers are cheaper, and it is faster than 1394b. ok, you might now say 800Mbps is as good 150MB/s, BUT: firewire uses a totally different (scsi-like) protocol to access mass storage devices, so the enclosures use a rather high-level firewire <-> ATA bridge. this one increases _disk access_ latencies, and limits the bandwidth. a ATA <-> SATA or SATA <-> SATA bridge is a fairly lowlevel bridge on contrary, so you have no problem with _disk access_ latencies and bandwith. it's just as fast as if the disk was internal. the only drawback is that linux currently doesn't support hotplug for SATA. so you have to plug / unplug while your PC is powered down. alternatively, you can load / unload the whole SATA driver, this should give you some hotplug capabilities. > >> >> At this time I'm planning for only one drive, but I can consider >> purchasing a second disk. > > I'm not sure it's necessary if you have enough RAM in your machine and > you don't do anything other than Ardour when doing Ardour, etc. > However, if you are recording with Ardour and running other apps at > the same time that are accessing the drive, then for brief periods you > will have apps seeking to different places on the drive and > potentially causing problems. > > One thing might be to go with a single drive and buy the second if you > decide it will solve some problem you run into later. > >> >> I'm still mulling over the distro possibilities.
