Ok, so the bandwidth will be cut in half, and some people use this

Will it hardly notice?
For a home server, I doubt you'll notice.
I've set up several systems (desktop & home server) as follows:
- two large conventional disks, mirrored, as data pool.
- single X25-M, 80GB, divided in three slices:
50% in slice 0 as root pool,
(with dedup & compression enabled, and
copies=2 for rpool/ROOT)
1GB in slice 3 as ZIL for data pool
remainder in slice 4 as L2ARC for data pool.
two conventional disks + 1 ssd performs much better than two disks
alone. If I needed more space (I haven't, yet), I'd add another mirror
pair or two to the data pool.
I've been very happy with the results.
