Not really correct at all in practice.

SDXC is backward compatible with SDHC when formatted as FAT32, the reason for incompatibility is purely a technical software one in that SDXC cards are formatted and sold in ExFAT format.
That covers the format side of things.

In terms of capacity then there can be problems when going over 64GB or the maximum official capacity supported in the SDHC format.

I'm sure there may be some technical difference on the hardware level, but in practical terms yet to see any time it's just the limitation of the adressable space that is the issue.

Thanks for the link to that Qumox one, crikey prices have gone down massively recently for 128GB cards.

I bought this card recently when it was £52! So, nice to see the price drop at last. However, I also got the Qumox card and it's hard to tell the difference, i.e. they both do the same work! lol

I'm using these in Blackmagic Pocket Cinema Cameras, so, if you need them for video stuff, they're pretty good

I bought 1 of these about 3 months ago....unfortunately it's now stopped working and its gone back to Amazon. I paid much more than this.

Will these work in an Asus T100

I can remember when 1gb cards were 50 quid and up !!

No, that takes a micro sd card.

I stand to be corrected quite happily but the following is information from the SD Association (link at end)

SDXC devices are backwards compatible with SDHC cards but the point was that almost all SDHC devices will not be able to recognise nor format an SDXC card. SDHC devices will only recognise upto 32GB
Now although you can often use a modern card reader or computer sd card slot to format an SDXC card so that some (not all) SDHC devices will recognise more of the SDXC card, it is uncommon to even correctly use the capacity above 32GB, and often this will cause errors and possibly early failure of the card, but more importantly formating an SDXC card using windows and any non SDXC device such as a card adaptor or most pc on-board slots is that the card will no longer be an SDXC, losing it's performance. As you can see on the SD Association website sdcard.org/con…xc/

I made this mistake once and was lucky that as I hadn't written to the newly formatted card, I was able to use recovery software to re-write the card back to an SDXC.

Nah, you're being lied to there.
There's definately a massive issue with compatibility above 64GB on the device level, but it's purely software, as in a limitation in the firmware not hardware.
The reason it says devices can't format SDXC cards is because that's true, but only on first use. If you open an SDXC memory card from new and check the format as stated earlier it will be in ExFAT format, all you need to do is a single format on that on your PC and it will be possible to format it in nearly all SDHC reading devices, it's a 1 time thing.

That website is just marketing talk and to save from support issues being raised repeatedly and keep a definied Yes/No type situation as to what will work with what.

It's no good having SDXC cards work with 95% of SDHC devices and stating as such on their official site only to receive millions of support requests from idiots who don't know how to format a memory card and so on
