My question is this: I'll be using 8 750GB SATA drives, and I''m trying to
But, is there a performance boost with mirroring the drives? That is what
I'm unsure of.
Mirroring will provide a boost on reads, since the system to read from
both sides of the mirror. It will not provide an increase on writes,
since the system needs to wait for both halves of the mirror

Mirroring provides a performance boost for reads since a read can be
done from either side of the mirror. Theoretically

I've had hideous luck with software-RAID and hot swapping, and from what I've
heard, Solaris is sort of iffy on support for hot swapping, so I'd like to
stick with the Areca.

It would have to wait on an fsync() call, since that won't return
until both halves

All I know is that the x4540 uses the LSI 1068e chipset, and that the
X4500 used the Marvell 88SX chipset. Since buyers of both of these
systems probably have an expectation that they'll well, work, I assume
that the drivers in Solaris should be relatively stable.
