I plan to setup a new system with four Crucial RealSSD 256MB SSDs for both SLOG and L2ARC. The plan is to use four small slices for the SLOG, striping two mirrors. I have seen questions in here about the theoretical benefit of doing this, but I haven't seen any answers, just some doubt about the effect.

Does anyone know if this will help gaining performance? Or will it be bad?

I don't know anything about these SSDs but if they might lose the last record or two then striping would be bad since it would cause more writes to be lost. Data would only be recovered up to the first point of loss, even though some newer data is still available on a different SSD.
