Nothing I would call quantitative. We have seven fileservers that handle the home volumes of about 15K active accounts (a little over a TB so far) each of which has 4 mirrorsets (8 drives -- Ultra160 SCSI, not IDE) and the only headache we have seen is a bad batch of drives about a year ago when we lost both drives in a few mirrorsets before we could get the first failure replaced and restored. The servers are a mix of Solaris on Netra T1s and Linux on homebuilt servers. Both seem to handle the strain of our level of access, and both do the mirroring in background -- I would expect that the IDE md Linux module would work just as well, just would be somewhat limited to two devices per channel, but you could get some of the high-speed secondary IDE controllers to add more IDE chains (IIRC the kernel will handle up to 10 IDE controllers these days) -- you should have a look at the kernel source for the pci-ide subsystems, 'cause there are some really snide comments about some of the chipsets that _should_ influence your buying decisions (one or two, but not all, of the Promise models, as I remember).
