64GB one. According to specs is up to 90 MB/s write and 200 MB/s read speed. Write speed spec is the same in theory as the 170 MB/s one.

Is actual M crop_rec build tweaked to 'golden standard' 170MB/s card?

I actually don't know! What we know: There is no way to predict how any card type will react to ML's overclocking method.
So referring to any spec is not valid.
EDIT: I wouldn't be surprised if 256 GB, 400 GB, 512 GB, 1 TB varieties showed different results. They are specified R200/W140.

Yesterday I did some tests with Extreme Pro and Extreme Plus R170/W90. They perform quite the same and allowed transfer rates above 70 MByte/s. Didn't test "anamorphic" modes, though.
Samsung PRO Plus R160/W120 performed well in benchmark but really sucks trying to record with overclocking and higher transfer rates.
