    Got my original hhd drive installed with a caddy by removing the ddv drive today

    Now when I run blackmagic spped test my Samsung Evo 250gig has gone from nearly 500mb's for read and write to 258!

    Is this related to installing my hdd today:confused:

    I presume then the lowered read/write speeds are normal after use?

    I think that the DVD drive connection is SATA2 whereas the HDD connection is SATA3, and that's most likely why you're seeing the SSD speed cut in half.
