How could it possibly be faster moving around files using a card? I can upload a file and it will become multiple copies on multiple devices before you can load it on one card on one device.
Whadaya mean you can do more with a SD card? What does a SD card do I can't using the cloud? There's SO much more possible with even a few gigs of cloud storage that you can't duplicate with a card. And since you're not limited by card capacity, your possibilities go nuts when you get more storage.
You don't get it because you're letting the limits of the SD card limit your thinking. You look at a new 128GB card and think about what it will do...
You have files. You have a card. It can hold xxx files in yyy device. You can access them easily on that device. You can put that card in another device, but only if it has a slot. Life is good. You want a card slot.
But if you think past the card and think in terms of 2015 technology, you understand you can do far more in far less time and with far less effort. The limitations of cards melt away. I have 1TB of cloud storage and think about what I can do..
I have files. I have cloud storage. It can hold xxxxxxxxx files and sync them to 6 yyy devices, load them all at once and access and share them from anywhere with anything. Life is sweet! I have no use for a card slot.
IOW, what I want and need - and what I get for not much money is:
A terabyte of space in one remote location, plus about 80GB spread over 3 other locations,
Immediate, real-time upload and backup, including all photos, documents etc,
Completely cross-platform compatibility,
Synced to 2 tablets, 2 phones, 1 Linux PC, 1 Win7 PC
All 4 remote locations cross-synced to each other,
Sharable with others,
Accessible from anywhere using anything with a browser,
Local backups plus backups in 4 separate remote locations, just in case of theft, fire or natural disaster.
And, I need all that to happen automatically, with no user effort.
I get all of the above for $220/yr. Read that list again. That's cheap for all that. And knowing that all our personal and business files always have up to the minute backups, multiple copies in multiple locations, really makes that low cost convenience and peace of mind.
Now, true I can't do all that for $20 but a shoebox full of SD cards can't do that list above at all. None of it. Well, I guess you could share the card, let someone borrow it. But then you don't have it so it's really not the same...
OK, sure it requires a internet connection for cloud storage to work. This just has not been a problem. Simple as that.
Now, tell me again why a SD slot in my phone is such a cool thing to have...
You like SD cards. Fine. Android is all about choice. I think it's time to move on and that they're about to replace floppy disks in junk drawers.
And that's all I'm gonna say on this.
