The one thing that always prevents me from using SCSI is replacement time. If the hardware fails, there are a million little PC shops I can go get a SATA drive at; SCSI is an order-in event, even in most bigger shops. And when you're talking about the number of drives (let along the amount of critical data) in our server room, replacement time needs to be short. As for SCSI failing less... my experience thus far has been otherwise.

But like you said, it's all about choice.

Well I don't know what happen from your side of the atlantic, but here
in italy if I have a support contract for same business day, if I call
they come, for EVERY need.

And the big company assure a wider range of tests and an attention to
construction quality that make the difference from an home made server
and a IBM/HP/DELL machine. There are small companies that are focused on
servers, but their prices aren't so different from $BIG_VENDORS ones

Don't agree. RAID Linux could be a valid solution, is flexible , but
it's not invisible, not OS indipendent and stress the CPU. The reason
why I choose scsi is AFFIDABILITY. sata is pretty new , scsi is around
since ages, it's bullet proof and outclass in performances a sata disk.
Obviously it's not cheap but what I spend now in disks I will not spend
after in time for changing broken disks and rebuilding arrays or worst
in recovoring. It's all about choice, just like gentoo.

well if you use raid5, it's pretty hard to divide the work, anyway 4
disks and 2 RAID1 systems could be a nice solution

yes ;) more approches to a common problem...
