One user bought a new PNY SSD expecting a Silicon Motion controller, but when they checked their new SSD found that it now had a sand force controller. It's not clear that this meant a performance degradation but the customer wasn't pleased to get a product different from what was commonly reviewed.
Another case involving Kingston they switched from synchronous to asynchronous NAND flash. This rendered the revised Kingston V300 SSD much slower than the version that was widely well reviewed.
Oops.
