Anandtech is where the articles were, I'd have to dig around to find them, but the recent Kingston V100+ review has some good info about it.
(EDIT: V100+ review:

It's not so much that the Sandforce doesn't have the issues on OSX, it's more it does have the issues despite being on TRIM enabled OS's.. meaning that Sandforce doesn't respond to TRIM like other drives do, it's more like a suggestion for Sandforce drives
When I first installed my OS and data, I could see my performance across my drive had fallen in benchmarks, despite having Windows 7 and confirming that TRIM was enabled.
Over time (months) I'd test every so often, and I could see regions of the drive bounce back up to near theoretical performance maxes, this was the Sandforce's garbage collector doing its work. It tries to strike a balance between performance and write amplification/degradation like all drives do, it just picks a more conservative place than some other drives do.
So it's not that the drive doesn't have performance degradation issues due to drive usage on OSX, it's more that the profile of how that will look over time will be similar on a Sandforce drive on Windows 7 and OSX given similar circumstances vs. other drives that might respond "better" to a TRIM command.
And as you kind of implied, the benchmark showing the difference and there being an actual noticeable difference is two very different things, especially on a laptop.
