2009 Mackbook Pro question

Thinking about buying the current 17" MBP and am wondering if anyone knows the 128MB SSD model/manufacturer, and the read/write speeds. Can't seem to find any info. The larger "256MB" is too pricey through Mac, and probably nothing near 200MBS R/W speeds.

Thanks in advance,
I don't remember exactly what brand Apple uses, but it's not an Intel or Indilinx-based drive (OCZ, etc.), which are the two that you want to look for. If you really want an SSD you're best of purchasing one with a normal magnetic drive and installing the SSD on your own.
According to this Macrumors forum it's a Samsung SSD: Brand of SSD in customized MacBooks?
