I'm doing it right now, with a pair of Seagate retail SATA drives 
connected to the SAS controller of a Dell PWS 690. The Fujitsu MAX3073 
SAS drives they replaced are sitting on my desk as I type this, and the 
system seems perfectly happy - though I did notice the drop in RPM from 
15 to 7.2k...

There's what appears to be an excellent article, "From 16 to 2 ports: 
Ideal SATA/SAS Controllers for ZFS & Linux MD RAID" at 
http://blog.zorinaq.com/?e=10 which recommends using a SAS controller 
with SATA drives. He mentions the x4200 and it's controller several times.

I'm taking this advice - I've ordered an LSI 9212-4i4e SAS controller 
for an external array of Seagate SATA drives currently hanging off an 
old 3ware 9500S with an, uhm, "creative" cabling arrangement...
