OWC offer SATA3 SSD PCIe Daughter Board
So if you do not have SATA3 and are stuck on SATA / SATA2 but do want to maximize SSD performance, OWC might have the answer for you, at the expense of a PCie slot though. Other World Computing announced the Accelsior S, a new PCIe card with direct mount support for a 2.5" SATA 6Gb/s SSD.
The latest addition to OWC's award-winning Accelsior line enables PC, Mac Pro tower and Thunderbolt interface expansion chassis users to quickly and easily add additional storage. Utilizing the robust PCIe architecture, the Accelsior S card offers both storage expansion and 6Gb/s speeds up to 550MB/s - more than double the performance of SATA 3Gb/s.
When equipped with the Accelsior S PCIe card and an SSD, Mac Pro tower and PC users can launch, capture, render and process I/O-intensive apps without long wait times. The Accelsior S PCIe card is also extremely easy to install - no drivers or software are required.
Performance Plus Reliability
Backed by a 3-year limited warranty and OWC's award-winning US-based 24/7 technical support, OWC Accelsior S cards have been developed to deliver consistent reliability well into the future. The OWC Accelsior S is custom-engineered for use with PC, Mac Pro tower and Thunderbolt interface expansion chassis.

Yep, way too overpriced imho. 57USD is simply too much. Few years ago for that rig in my sig (X58 mobo without SATA3, just SATA2) to use it with Intel 520 series 120GB SSD as it's meant to be on SATA3 I've bought Transcent PCIEx 2.0 x4 combo SATA3/USB3.0 controler card for just around 20€. If the price is 20$/€, even 25$/€ that would be OK, but 57$ is way too much.
btw, cards like this OWC Accelsior S (for fair price, of course) could be really nice upgrade for all running SATA3 SSD's on non-SATA3 mobo's.

if it was cheaper i'd consider one or two, i have multiple free PCI lanes and would love to get rid of some power / SATA cables that run to my 2 SSD's if i could help it

wouldn't pay in excess of $100 for them though.

Looks like they used a run of the mill multipurpose USB/SATA/PCI-E controller, slapped on a cheap PCB. Better save some extra cash and go for a true native SATA-6G with a new (or second hand) mobo. Those auxiliary controllers usually suck at write speeds anyway.

57USD, not worth it. Max 15USD.
