I use a Blackmagic Hyperdeck to record ProRes video to SATA SSDs and was looking for Thunderbolt adapters to ingest the files into FCPX.
The obvious choice is the Blackmagic Multidock, which comes with 4 SATA II slots at 3GBit/s and one Thunderbolt 1 port. It’s around $500 and delivers a combined read/write rate of up to 10Gbit (out of theoretically available 12Gbit) on all ports simultaneously. Not bad at all, but my guess is that a Thunderbolt 2 / SATA III version with 20Gbit (out of 24) should be just around the corner, possibly at NAB in April.
Update 2014-03-19: It’s available now in a Thunderbolt 2 version!
Another choice is the Seagate GoFlex series of products. But I wish everyone good luck finding out specs and availability for the multitude of different models, in 3.5″, 2.5″ with and without included hard drives. I gave up.
Don’t buy it anywhere. They don’t want you to.
The third candidate is the LaCie eSATA Hub with two eSATA II ports and two Thunderbolt 1 ports to daisy-chain it. Again, I’d love to see an updated version of this with (e)SATA III and/or Thunderbolt 2. This wouldn’t profit as much from Thunderbolt 2 as the Multidock, but it could squeeze out 2 extra Gbit/s at the top end. At under $200, this would have been my first choice, if I wasn’t waiting for a new Multidock and I wouldn’t have discovered the Delock adapter.
The only readily available adapter I could find that has a SATA III port is the Delock 61971, a sorry little generic aluminium box. One drawback besides looks and mechanical stability: despite the minute size it requires an external 12V power adapter. On Mac OS, it just works. Windows users get a Mini CD with a driver. Data transfer rates on an Sandisk Extreme and an Intel 335 SSD are way under their respective data sheet specs, but close enough to 3GBit/s. It’s currently priced at about $100.
The device appears on the Thunderbolt bus:

and an SSD connected to it will appear under the Thunderbolt AHCI Controller

Performance in FCPX looks promising as well: With ProRes 422 720p50 footage on the external SSD, rendering and transcoding a 3 hour program to ProRes 422 720p25 to the internal SSD on a current MacBook Pro takes just under 20 minutes.
