Once it's $150 and has U3 speeds, I'm buying 2 of them. I take 12 hour long off-road motorcycle rides and have a GoPro facing backward and TomTom Bandit facing forward affixed to my helmet. I plug both into my bike so they stay charged but in 4K, I have to change cards way too often. This would allow me to record 4K video all day w/o having to change cards.

Sorry, but no. According to Samsung, the Note 8 only supports microSD cards up to 256GB.

Wrong.

They always say that as the largest available was 256. I guarantee 100 percent this will work to the microsd xc specification.

The XC spec goes up to 2TB ;-)

Note:
"Most recent Android devices that offer a microSD slot will support the new 400GB chip out of the box, meaning you can get your phone up to almost double what the top-end iPhone currently offers in onboard storage.

The SanDisk 400gb microSD card can hold up to 40 hours of 1080p HD video, Western Digital notes, and offers transfer speeds of up to 100mb/s. It’s also designed to comply with the Android A1 App Performance Class specification for flash memory, which means it can load and run apps faster when operating as adopted internal storage."

BOOOOM!

Assuming Samsung didn't put some weird firmware limitation for 256 that would have to be patched. 400 will probably work out of the box, but no guarantees.
 
400GB @ 100 MB/s, how many years would it take to load it? :p
Not sure I would want this card under load for more than a half hour - I would probably melt.
400GB / 0.1GB/s = 4000s
So, a little over an hour if transfer rate holds.

How is it possible to have so much storage on such a tiny thing?

My first thought also. Even when the earlier MicroSD cards started hitting around the 4GB mark I was blown away by what they could fit into a sliver of plastic. 400GB would have been unfathomable to me. Truly amazing stuff.

As the transistors get smaller and smaller, you can fit more and more into smaller and smaller spaces. It is truly amazing. Star Trek's world of nano robots that can repair cells is not far away.

I remember the first 1gb microdrive and CF cards....they seemed amazing at the time in a pocketpc :D

They've never done it in the past.
I've put 128GB cards in an S4 that was only rated for 64GB.
As long as the card is compliant to the SDXC standard, it should work just fine.
 
Again making you wonder whether Apple removed the SD card slot to cut off expandability, which is just pathetic but might have influenced the decision.
People spend a lot of time assuming Apple goes out of their way to make things hard on purpose. This quickly gets into tinfoil-hat conspiracy theory territory. They're not trying to kill your fun, they just have different goals in their sights (soldered components are harder to replace, sure, but the goal is compactness and reliability, not screwing over the consumer).

400GB in the palm of my finger.
Sentences that would be unthinkable 20 years ago: "here's 400 gigabytes of storage - don't drop it, we might not be able to find it again."

It often occurs to me that if I could take my iPhone back and visit 12 year old me (an avid Star Trek fan), and show 12yo me my iPhone, and explain all the various things it could do, and show movies and music and photos stored on it, and list off all the capacities: gigahertz 64-bit processors, gigabytes of memory and storage, tracking satellites to determine its location on the planet to within a few feet... and then explain that this particular one was 3 years old and considered a little slow and underpowered, and basically everybody had one similar to this and carried them around all the time, communicating in unimaginable ways... 12yo me would refuse to believe that I was from the year 2017, insisting that such miraculous technology couldn't possibly exist for another several hundred years. Why, Captain Kirk, in the distant future, could talk to an orbiting spaceship with his communicator, but only via audio - we can video conference with people living in space.

We don't notice that we're living in what was (recently!) science fiction, because it creeps up on us.

Twelve year old me would love the part about how we mostly use all this tech to watch cat videos though.

I still have a 64mb micro SD sitting in my drawer...I can't bring myself to throw it away :)
 
Hmm, can't wait to see the first reports of 800GB PSPs.

Will take forever to boot, but by God, having close to a TB of storage on a portable console of that age just makes me drool.


Plenty fast for many things like an iTunes library, iOS device backups (those suckers are HUGE, especially if you archive some states), home videos, download folder, etc...

Just manage where you put which files.

For example: don't set your work directory in FCPX to this card.

As long as the OS and the common applications are on the SSD I think for many this could be the workable solution Apple practically forces you to go with unless you like paying high premiums for fast storage when you really only need a fraction of your storage to be fast.

Sure - as I said, its possible for archival and backup stuff - but still, I'd rather have one volume. You could roll a Fusion Drive with it but then your system is down if you remove it.

There are always useful compromises with cost but meh, I just went for the 1TB SSD and it's more than enough space than i'll ever need on my MacBook Pro. Plus it's £360 (without discount) to go from 500gb to 1TB of SSD and this SD card is $260 for 400gb.

Even if cost was the utmost importance I doubt the £100 saving when you've got a MacBook Pro is going to be life saving - but the hassle of managing two storage devices, one than is 100MB/s and one that is 3000MB/s would be a hassle.

The difference being that this sucker is going to drop in price much sooner than Apple ever will move its capacity offerings or make the respective options cheaper.

And boy do you not want to make this a Fusion Drive. Just symlink stuff or set default paths.

Also a great way to buy into the Mac now and expand storage later on down the road... You know, like you were able to for decades until everything had to be set in stone at the time of purchase.

Amazing. Remember when a 20MB (MB not GB) First Class Peripherals Sider II hard drive for Apple II was $900. Going to wait for Samsung version, though, with 10 year warranty.

How is it possible to have so much storage on such a tiny thing? Doens't this mean, you can build 2,5" drives with 40Tb?

There are ~$25 SATA adapters that take 10 micro SD cards so potentially 4TB.

...without any backup. Eh, nope. Not me. Lol.

I still have a 4GB CF card in my 5D mkii. I never get more than 30 photos in without copying off, editing, sharing and backing them up. Even that is overkill. Not to undermine the importance of your comment about backups, but I was being slightly ironic.

Not really - there's no SD card slot now...

It's all cost and compromise related though and as I said - unless its going to be a similar experience for at least £500 less it's not worth me messing around for - and this isn't that.

Well, to be frank I'd just suggest getting a refurb with an SD slot.

If you really need the latest model though... Yeah Apple closed that whole path, the only remaining option is a USB-C flash drive dongle that sits flat if that exists...

And yes, like with so many things, ymmv

I'd never got back to a 2015 model, the 2016 and 17 have been superior in every way.
