2TB Micro-SD Card?

dvhttn said:

Manufacturers say 'up to 2TB' because that's what the card format supports - see ... https://en.wikipedia.org/wiki/Secure_Digital .... for more information. "IF" we ever get microSD cards that c an be manufactured above this capacity then they'll have to come up with a new one - or an 'extension' to SDXC.

It's a change from the early days of 'smart' phones when the manufacturer would state support for cards up to 'xGB' where 'x' happened to be the largest card they could test with but soon after launch we could buy cards with '2xGB'. All the forum questions back then were 'but the abd V37-lite says it supports up to 16GB. Will this 32GB card work ...'.

Basically, if a phone supports the sdxc card format then any card UP TO 2TB can be supported. As I write this I believe we do have at least one 512GB card on the market and Sandisk have their 400GB one.

I'll still contend that it's safer to just follow whatever limitation on card capacity is listed for your phone. Simply because a larger capacity card can fit into the card slot doesn't mean it's also going to be a stable and reliable storage media. For those who aren't worried about increasing the chances of losing files and just want a lot of storage space, go for it. Also, in that same posted link there's a section on 'Compatibility':

Yes, the 'limit' is the SDXC limit (these days anyway) which is 2TB. But I made no comments or references to how safe this would be or to card compatibility, just to what the format(s) support. In my case if my phone was stolen/card lost or broken I would lose nothing except, possibly, a few recent photos. My card is just a copy of 'stuff' that's on my PC, which is backed up fairly (ish ...) regularly. But YMMV .......

Well, as you want to make an issue of this, you did state:
"Basically, if a phone supports the sdxc card format then any card UP TO 2TB can be supported. As I write this I believe we do have at least one 512GB card on the market and Sandisk have their 400GB one"
the clear implication being a phone that can use SDXC cards will include support for any size capacity for SDXC cards, which is most definitely not the case. Most phone manufacturers limit card capacity to older standards, preferring proven reliability over maximum card size as there's not any history of stability nor reliability. Also, by using an anecdotal suggestion to anyone to use as large a size available, negating a manufacturer's recommended limit, is a risky thing to do. While you may not care too much about losing few photos, there are others who could possibly lose irreplaceable data following your implied advice.

That's just wrong. For instance, saw the specs. for a phone recently where it said 'support yp to 128GB ..'. Which 'older' standard is that? As I said, they just support up to the biggest they had for testing OR say 2TB which is the SDXC limit.

It has been shown on many, many occasions since smart phones started to use sdcards (see this forum and xda for the MANY examples), that using larger than the manufacturers 'recommended' is not a problem, bearing in mind sd card formats and limits etc (not so much now with the 2TB limit which we haven't reached yet). As for my 'implied' advice, why not mention the ACTUAL advice, which is to back up your stuff?

I'll leave it there ...

But you're cherry-picking examples just to suit your argument. There are also many, if not more, postings from people with problems countering your advice to just use any card irregardless of whether it's supported or not. Again, I think giving others risky advice based on your own wishful thinking is not appropriate. If you don't care whether you lose data or not is not the topic of this thread.
