SD cards can go up to 90MB/s
under ideal conditions, which - like every class rating except A1 - are strictly sequential writes only 😀
Mind you, it's the same for CFs and all other consumer grade memory cards - which in their respective heyday all pandered to people not wanting to bottleneck their expensive digital camera when used as directed (= reformatting in-camera "before every use")
90 MBps is also tautologically more than 25, so clearly an UHS speed requiring an interface capable of those modes - not likely when close to 100% of those SD to IDE converters use a rather old chip;
even more, a picture search for "v90 sd card" only shows UHS-II cards - the ones with extra pins required to do 8-bit transfers, that pretty much only caught on top end cameras… the ones that until recently kept CF in the market and are nowadays pushing for proprietary and/or stupidly expensive cards that you can't buy in electronics or dedicated computer stores 😀 🙁
Tldr - It's quite likely for what you're asking for to have never been invented to date 🙁
