    So last year the MBP 15" got 1500MB read and 1800MB write speeds for the 512GB and 1TB models. Anyone think it's possible the new rMB (512GB) will get that high? I know no one really notices the speed increases in day to day usage, but it is really cool nonetheless. :)

    so just tested it with black magic design (v2.2.2) disk test and peeks at write 984 read 747 ... YMMV

    Thanks, just one more question, was this the 512GB storage model or the 256GB? Thanks again.

    I read a review earlier today from some site that had both 256 and 512GB rev B. Macbooks, and they showed about 1200 Mb/s read and 700 Mb/s write speeds for both drives. They were identical in that aspect.

    So AFAICR this means read speeds are doubled and write speeds are similar, compared to the 2015 model.

    The SSD in 2016 MB is PCIe 3.0 x2, so maximum real world bandwidth is about 1600MB/s, which the 512GB model seems to achieve. MBP is PCIe 3.0 x4, hence it provides higher performance.

    Cool thanks everyone. I am planning on getting the 1.2Ghz model in the next month or so, if the read/write speeds are as good as you are saying, then i'm all in. It also looks like the 1.2Ghz model's processor is much better as well, (I think the 1.1Ghz is a waste and rather a joke in performance.) I was hoping Apple would have upped the base model to 1.2 or 1.3 this year, but atleast I'll get faster SSD and more storage by getting the mid-tier model. So far it will take a good 2 months for me to be able to save up and buy this sucker and not break the bank. lol

    Its the m5 512GB 8GB cloned from my 13 rMBP (Now sold)
    --- Post Merged, Apr 23, 2016 ---

    I would not worry about "Performance" i have the m5 8GB 512GB for the last 3 days... and in most real world usage it beats my "OLD 13 rMBP mid 2014 512GB 8GB" hands down ... cloned it so that like for like ... even battery seems to be better "Like for Like"

    YMMV

    The battery is definitely better on this one.

    My old "2 week old" 2015 rMB drained much quicker.

    I've used this a couple of hours throughout the day, and it's at 93% still
