Subject: Anyone running Intel S3700 SSDs?

Considering this list is where I first learned of the Intel 320 drives (AFAIK, the only non-enterprise SSDs that are power-failure safe), I thought I'd see if any of the folks here that tend to test new stuff have got their hands on these yet.
I had no idea these drives were out (but they still are a bit pricey, but cheaper than any spinning drives that would give the same sort of random IO performance), and while trying to find a place to source some spare 300GB 320s, I found this review:
http://www.anandtech.com/show/6433/intel-ssd-dc-s3700-200gb-review
Of most interest to me was this:
"Along one edge of the drive Intel uses two 35V 47µF capacitors, enough to allow the controller to commit any data (and most non-data) to NAND in the event of a power failure. The capacitors in the S3700 are periodically tested by the controller. In the event that they fail, the controller disables all write buffering and throws a SMART error flag."
This is also the first new Intel drive in a long time to use an Intel controller rather than a SandForce (which frankly, I don't trust).
Anyone have any benchmarks to share?
Are there any other sub-$1K drives out there currently that incorporate power loss protection like this and the 320s do?
Thanks,
Charles
