SD card speeds D750

New d750 arriving shortly, but I'm yet to buy some cards.

Having found sandisk ultra 30mbs cards unsuitably slow in a d610 and their Extreme Pro 95mbs only just acceptable does anyone have any figures or is there a comparison table anywhere? With the 610 I found the slower cards would freeze my camera all too often, the faster cards still can have an overly long delay in reviewing images on the fly.

I know the figures are the read speeds and it is the write speeds that matter.

If the better buffer on the 750 makes the 30mb cards acceptable I'm good to go, I'll finally make use of the slower cards I already own.

If nobody has the figures I need I'll post my findings early next week

Here's how 95mb cards perform on my 610

High speed burst, then when the buffer filled at 15 shots I kept my finger down for a further 5 shots, took a time at this point then a time when the green light indicated the files had completed their write.

Writing to both cards: 8 seconds then 26 seconds (total) to clear.

Removed one card and repeated: about 6 seconds and 12 seconds (total) to clear.
