The main purpose for using SSDs with ZFS is to reduce latencies for synchronous writes required by network file service and databases.

In the "available 5 months ago" category, the Intel X25-E will write
sequentially at ~170MB/s according to the datasheets.  That is faster
than most, if not all rotating media today.

Sounds good. Is that is after the whole device has been re-written a few times or just when you first use it? How many of these devices do you own and use?

Seagate Cheetah drives can now support a sustained data rate of 204MB/second. That is with 600GB capacity rather than 64GB and at a similar price point (i.e. 10X less cost per GB). Or you can just RAID-0 a few cheaper rotating rust drives and achieve a huge sequential data rate.

I see that the Intel X25-E claims a sequential read performance of 250 MB/s.
