Mid 2008 128GB Apple SSD vs Mid 2010 128GB Apple SSD: Any differences?

[8767092]

As the title says, does anyone know the differences between these two?

Do the upgraded Apple SSDs have the newer Samsung firmware that will enable garbage collection?

The new SSD is a generation better than the old one- much faster and has the equivalent of what the Indilinx drives call "garbage collection".

Does anyone know which Samsung models that Apple are using at the moment?
