I was testing a Crucial M4 6G SSD and I dropped it in a Mercury Elite AL Pro Mini enclosure and connected it via eSATA to an OWC Maxpower eSATA card (the non-RAID one). I only get about 125 MBs read. If I move the M4 internal, I get the expected 250-260 MBs read (3G channel). If I move my 3G OWC SSD to the external enclosure, I get the expected 250 MBs speed. Is there some compatibility issue with 6G devices and 3G eSATA controllers or bridge chips? THe eSATA card is rated at 6G, but the bridge in the external is only spec'd at 300 MBs (3G). What the hell is going on?
