128tb not bad but the rest of us won’t get the purchase option.

985MB/s might sound impressive at first for an SD card, but if there comes a time when a 128TB card hits the market, . . .

128TB = 128,000,000MB (disk capacity)
128,000,000 / 985 = ~129,949 seconds
128,949 / 60 = ~2,149 minutes
2,149 / 60 = ~35.8 hours

. . . offloading that card is going to take a while!

Or worse losing all that data in one big shocker…
