How much space is needed for my partition? I don't plan on using the Windows install for much else, since this computer is for work only.

MacBook Air, Mac OS X (10.7.4), 128g

    then why not get Office for Mac? Excel does better on Windows. 128GB is small and Windows would be a waste for you of 40GB, and SSDs need room for TRIM  and GC on each.

     

    Why not run a VM like VirtualBox, or try that first.

    So you do know though what VM could do for running Windows and Word; and there may be support with CrossOver Mac (never used it but it is supported and was updated for Mountain Lion too).

     

    VirtualBox is free - hold off activating until you know if it works for you.

    TRIM and Garbage Collection are how an SSD manages and orders SSD NAND cells and pages where data is stored.

     

    Garbage Collection (GC) is the process of relocating existing data, deleting stale data, and creating empty blocks for new data 

     

      NAND flash cannot directly overwrite a page with data; it has to be first erased 

      One full block of pages has to be erased, not just one page 

      GC starts after each page has been written one time  

    ....

      The OS tracks what files are present and what logical blocks are holding the files 

      SSDs do not understand the file structure of an OS; they only track valid data locations reported by the OS 

      When the OS deletes a file, it marks the file’s space in its logical table as free  - It does not tell the drive anything 

      When the OS writes a new file to the drive, it will eventually write to the previously used spaces in the table 

      An SSD only knows data is no longer needed when the OS tells it to write to an address that already contains data 

     

      How Trim Works -  

      The OS sends a TRIM command at the point of file deletion 

      The SSD marks the indicated locations as invalid data 

      TRIM Features: 

      ►  Prevents GC on invalid data 

      ►  Increases the free space known to the SSD controller 

      TRIM Benefits: 

      ►  Higher throughput – Faster host write speeds because less time writing for GC 

      ►  Improved endurance – Reduced writes to the flash

    Your SSD only has about 111GB out of the 128GB for use, and it needs 10% (more is better) free to operate and perform at reasonably acceptable write I/Os.

    Boot Camp means you get to run Windows natively, but that uses hard drive space that is very limited.

     

    A VM lets you run Windows "under" or inside OS X which is convenient and does not eat up as much disk space, but means that when you run Windows you are sharing your RAM (hopefully more than 4GB) and your processor (an i3 dual-core is not gong to run both well). Higher end Air ? 2012?

    It's the brand new Air that just came out last month. 4 gigs of ram though. You think that would do for VM?

     

    All i'm gonna use Win7 for on this Mac is just to run word and that addon program called Translation Workspace.

     

    4 gigs is somewhat small for  Windows in a VM, but the very fast hard drive (ssd) should make it liveable, download a trial of the VM you wish to use and try it out.

    did you try VirualBox to see if it works?
