As far as I know, from the drives on your list, only the LG (like all LG drives) reads DVD-RAM. As for its ripping speed, I'd call it good, although not excellent. But that's mostly from reviews, I never owned one.
Oh, and a DVD-RAM cartridge is sort of like a DVD-RAM disk which you never remove from its box. It's used mostly to protect two-sided DVD-RAM media, and must be used in any reader/recorder WITH the cartridge. Naturally, the standard CD drives don't read those, not because it's a different format, but due to purely physical reasons.
