Do Meraki Switch SFP Ports have a higher buffer than the Copper Ports?

[RH6379]

We're debating whether to purchase SFP modules for our Meraki MS120-24's and use those as uplinks or just use one of the copper ports.  My boss mentioned that the SFP ports might have a larger buffer.  Does anyone know if that's true?  Also, is there any documentation that talks about that and how/if the ports are split up into ASICs?

the cobber interfaces is Marvell Alaska V 88E1680 chips and the fiber is Marvell 98DX3233A1. Maybe marvell has some spec. pdf.

Memory is SK hynix - https://www.skhynix.com/products.view.do?vseq=913&cseq=74

and Nand flash from Spansion.

It´s all the same hardware in the 120 series and nothing home grown. All bougt from other venders.
