2015 rMBP 128/256/512/1tb ssd performance difference

[mfa81]

I can't find this info anywhere, I'm trying to find out if there is any difference in performance between the 128/256/512/1tb ssd options on the new rMBP

does the upgrade price gives us anything other than more space?

tks

There are speed differences according to black magic tests, quite significant I think, however only read speeds I believe. And I highly doubt it would be noticeable anyway.

Between the 128GB and 256GB, yes, especially in writes.

Between the 256GB and all other capacities, not much.

But in real world performance, the difference is almost nil.

sequential read/write speeds only make a difference in very specific use cases and when copying huge files.
