    I'm going to purchase a new MBP when they're refreshed in the spring. I'm considering getting my first SSD. How much available space is on the 128GB SSD?

    I've had my current MBP for 3 years next year. Out of the 250GB drive, there was 232 available to use when I got it. Out of that, I've only used around 32 GB (most of my files are kept on the iMac).

    Anyway, let me know what available space I should expect on a current MPB with an SSD. I definitely want to make sure I have plenty of storage, but that extra $450 in my pocket would be nice, too.

    Dont buy the SSD from apple, you can buy faster cheaper SSD's elsewhere. A 120GB SSD is like $250 most places.

    My 240GB SSD says there is 240GB total space on it. OS X uses about 6GB of that.

    I would expect the 128GB SSD to actually be around 119GB. Though Snow Leopard will report 128GB.

    If I recall correctly. Apple changed the way OS X reports capacity. Rather than using the true binary number it reports the base 10 number that marketers use for selling hard drives. Your drive would actually be around 224GB.

    I had assumed that since SSD's were being marketed at base 2 numbers such as 128GB and 256GB that the industry was actually listing their actual capacity.

    I have the 128GB SSD from Apple in my MBP. First boot it had 120GB available. It's only a $200 upgrade over the standard HDD. Don't let these SSD snobs get you all paranoid about choosing an SSD. Only time will tell how an SSD will degrade if at all.

    I've used between 50-100GB of data the last like 5 years. Usually its around 70-80. It sounds like a 120/8 is all you need. Keep in mind that some data you rarely use can just be thrown onto an external. It's worth getting a SSD with built in wear leveling software (hence the 120 versus 128 IIRC)...most SSDs do have some form of wear leveling software.
