    I've seen that the MBA 11" 128gb gets about 4xx mb/s and the 13" 512gb gets 7xx. Anyone seen any benchmarks for the 13" MBA with 128gb and 256gb?

    The 128s in the 13"s also get 700+ writes, there are several benches on here. The 256 will likely have about the same.

    So then it's confirmed that the 13" 128GB SSD is almost twice as slow than the 256GB? :(

    I couldn't justify spending the extra £190 on an extra 128GB of space so I went for the 128GB SSD. Had I known I'd get such a huge improvement in write speed I definitely would have chosen the 256GB SSD.

    In real terms, let's say I'm saving a Photoshop file that takes 2 minutes to save on the 128GB SSD, would it therefore only take about 1 minute and 15ish seconds to save with the 256GB SSD? Or is it not that sort of exact difference due to other factors?

    Really gutted I'm missing out on that speed increase when there's no indication at all of this on the Apple store specs!

    What are the chances that my local Apple retail shop has 8GB RAM/256GB SSD models in stock? I don't have the time available to wait for another online order to dispatch but I wouldn't mind returning mine when it arrives if I can just go to the retail shop and pick up the one I wanted instead.

    I doubt you will notice much of a real world difference. I have a macbook pro with an intel 80gb ssd in it (x20m) and it is super old, sata2 and I can't notice a difference in daily usage compared to the ssd in the air which is MUCH faster in both read and write

    So my example, a file that takes 2 minutes to save on a 128gb with the 400 write speed... wouldn't take approx. 1min15secs on the 256gb due to the faster write speed of 700?

    Because if it was like that then I definitely would notice...

    If that's the case, then the file would be 400MB/s x 2 x 60s = 48GB in size?!

    I'd say that's not how it reflects in real world usage. Coz in saving or rendering even, the processor is doing its things too. I might be wrong though.

    Ahh, I guess I really should have done the maths there.

    Just shows my ignorance of how stuff like Photoshop works! So when a 100MB~1GB Photoshop or Illustrator file is taking a few minutes to save it's probably more down to the processor than the write speed of the hard drive?

    Sorry, don't mean to drag this off topic, though I guess there will be other graphic designer-types in a similar position feeling they missed out on that write speed. It does seem like I sometimes spend half my time stating at 'saving file' dialogues!
