    Hi everyone,

    I was wondering if anyone could tell if there is a difference between the 128g m4 Crucial and the 64g one as I've picked up some comments about the one with the higher space is better performance wise?

    The 64GB version has write speed up to about 100MB/s and the 128GB version has write speed of up to about 190MB/s.

    Both models can read at up to about 400MB/s.

    You probably won't notice the difference.

    Half the chips, roughly half the bandwidth. Still a whole lot faster than HDD.

    Latency/access time is generally the cause of perceived HDD "hangs", and what gives SSDs the snappy feel.

    I get a bit over 100MB/sec out of the 64Gig drive actually. Up to 108MB/sec.

    Obviously the 64Gig version wont hold a huge amount, mostly just for an OS drive, but it does that really well.

    I'd look at 4k writes over any sequential read/writes for a far better idea of everyday performance.

    Thanks for the input guys :)

    Any links where I can find info on user posted comparisons between the 64g vs 128g m4?

    Well the M4 thread would be a good start.
