    Any concern that a 256GB will be slower than a 512GB SSD? Looking at a 13" MBP and trying to decide on the HDD. Space isn't an issue, just concerned about speed.

    There is no 'slow'.

    256GB is 'very fast', 512GB is 'super fast'

    Hmmm... not sure that answers my question. Maybe this isn't a valid concern. Just reaching out.

    512 is faster but not really perceivable in day to day use. if you don't need the space save your money

    What use do you have in mind where you think the speed difference will matter? There is most likely a significant difference for moving large files, but for most things you wouldn't notice.

    Doing some school stuff and programming. I do need to run a Windows VM for some visual studio work. That's about it.

    Speed aside, both are fast enough for you not to care. Space should be your primary concern. As a programmer myself and also using VM's (among the many other apps needed for development work) I found that I really pushed the limit of a 256GB SSD before too long and had to upgrade to a 512 (on my iMac.)

    I noticed a considerable difference when I switched. Not just because the drive was faster, but also because there was a lot more free space on the drive for swap files and so on. Whereas with the 256 I had got to a point where there was almost no space at all for swap files and caching.

    Of course that'll depend entirely on how many apps you install and how much storage your files take up, along with the VM's.

    I'll second that, you'd probably want to keep at least 10% of your drive free for cache, swapping, logs, indexing, vm snapshots etc. Speed of ssd is the least factor to consider, they are both very fast.

    See my earlier post here from another thread. There is some difference, but in normal usage you will never notice the difference. If you don't need the added space, it is certainly not worth spending the extra money on the 512 just for the speed.
