    I installed a Samsung 256 ssd in my MB Pro unibody 15 this am. I cloned my existing hard drive to the Samsung using Super Duper and a Wiebe dock with SATA connector.

    I then pulled my Hitachi drive out and put in the Samsung. Seems like there is a few bugs. The machine has froze twice while using it in the last half hour.

    I then ran Xbench and the numbers didn't seem what they should be. Here they are:

    Any thoughts?

    Friend of mine did the same thing. Turns out it was the clone that was screwing up. So he just formatted his ssd and a fresh install of osx. Later he just added the files from his old backups back to the new install.

    this i just got from the superduper-developer:

    An SSD is a drive like any other. Copying with SD! to it works fine. If someone had "freezes" it was likely due to something else.

    For an SSD those scores look very low. Maybe someone else with the same drive can post their score?
