    Hey guys, I'm debating moving to a 120GB SATA3 SSD from the Toshiba that my Air came with.

    What I'd like to know is:
    About how much will the battery life suffer? Maybe 30min?

    Will I notice much of a gain in real world performance? I do a lot of file transfer and work I with a lot of documents and code files.

    Would is be perhaps a better idea to find the Samsung SSD that the Air came with? I have the Toshiba right now as I previously said.

    SATA2 -> SATA3 will only be noticeable for large file transfers. While SSDs excel at those too, the main speed benefit they offer is for small files and find latency which, as far as I know, is not improved with SATA3.

    So unless those documents and code files are gigabytes in size, the difference in speed will not be noticeable.

    Someone correct me if I'm wrong on SATA3 with small file read/writes.

    EDIT: My entire reply assumes you're going from SSD to SSD. It wasn't very clear in your OP.

    I am also a little confused, your sig says your MBA has an SSD already and it seems to imply to want to switch to a smaller SSD. A little clarification would help.
