Micro SDHC vs SDXC

Wanted to know the difference?

I have the Sony RX100 and it says I can use regular SD cards for SD, HC and XC. For micro cards, it says I can use SD and HC.

If I use an adaptor with a micro SD card, would using a XC work in this case now?

Thank you,

just means a standard for a certain capacity range
you're better off googling reviews of each card to find its speed
yes micoSD to SD adapter is fine, in fact I rarely buy full size SD now for versatility, unless i'm splurging for the Sandisk Extreme Pro with a large capacity
for my RX100 I use the Samsung Evo Select
for the love of god, buy it off a reputable retailer, so no third party amazon/ or alixpress finds

Thanks for sure will buy from reputable seller.

So if I buy a MicroSDXC with the adaptor, it will work?

For some reason, the manual does not list MicroSDXC, just MicroSDHC.

If I was to get regular SD, maybe this in 32GB:

For Micro, maybe this with the adaptor in 64GB:

It'll work but it might be slower with the MicroSD

Oh MicroSD may be slower? I assumed other way around. OK that's good to know.

like i said, just gotta look real world speed of each card
a microSD made last year will proably be faster than a SD card from 6 years ago, there's no firm rule

I remember trying to find the difference for the different SD card.
One thing I noticed is that HC corresponds to 32GB or lower and XC usually is anything above 32GB (i.e. 64 GB +).

I don't think the HC/XC indicates the speed of the SD card, as the rates are classified differently. (e.g. SDHC Lexar 633x vs SDHC Lexar 1000x)

For your adapter, does it say what the adapter supports? My assumption would be that all adapters are wired the same.

adapter is just a physical connection
its effect on speed is negligible
i have not confirm this, just using good old logic
