Been running SATA SSDs for L2ARC with SATA/SAS interposers for a while
now without any issues. It's not ideal, but workable. One really has to
think of it as a trade off. If you want performance, no questions asked,
be prepared to drop the $2-4k for 1-2 ZeusRAMs per machine. For people
who are willing to compromise a little bit, you can still get decent
performance at about 1/4 of that price by using a pair of Intel DC S3700
200GB SSDs attached via interposers. YMMV.
