    Sorry to start a new thread on this but all previous discussions were like 3 years old...

    I bought my 2009 Macbook Pro a month after it came out and about a month after that some of you might remember that there was an issue where people installing SSDs were only getting SATA I speeds (1.5 gbps). Then Apple issued a firmware update to fix this and give people SATA II speeds but it caused a lot of problems for people with 3rd party hard drives.

    I had a third party hard drive installed and since I didn't need SATA II speeds at the time I just stuck with the 1.6 firmware and ignored this update.

    BUT now I just installed a Samsung 830 256gb SSD in my macbook. Installation went perfectly fine but read and write speeds aren't as good as I was hoping and I figure this is likely due to SATA I speeds my SSD is working at (I checked in system information).

    I haven't heard any issues recently with regards to this EFI update...will this work with my macbook pro or will i get the horrible beachballs. Anyone with a 13inch 2009 Macbook pro and a Samsung 830 drive have any input? Thanks!

    I am interested in this configuration as well. I currently have an 80GB Intel X-25M in my mid 2009 15" MacBook Pro (MacBookPro5,4) running EFI 1.7 with no problems. I've ordered but not yet installed the 256 GB Samsung 830 drive.

    Saturn1217, have you upgraded EFI to 1.7 yet?
