On Amazon, that too .ca? Unbelievable. Don't they have a flagging systems or something?

That one might be fake but terabyte miroSDs do exist.

Some companies are taking pre-orders on 1TB microSD cards, but the prices are in the $4-500 range.

What's with the names on the related products...

What's next? A 10TB micro-SD card for $39.99?

Sandisk also make a 1TB MicroSD.

Does anyone like this price?

Just came across this... I think someone is having a bit of fun here.

Note that in spite of the delirious item description, and all the bad reviews, the product is still available on Amazon, and the seller as well. Should tell you something about how seriously Amazon cares about its customers.

Edit: the product is not available anymore actually. But I just don't get why the product page is still there.

"I know it's fake, but I couldn't resist the price."
Don't laugh, it happens.

Does 400GB static storage even exist? Doesn't it use the power of 2?

[amyk]

Could be 512GB with 112GB of spare area... which given the abysmal reliability of high-density flash, might actually be realistic. SSDs have also been available with non-power-of-2 sizes for a long time.

I bought a 400GB microSDXC card from a supplier I trust and it had ... 400GB of usable space. (Decimal gigabytes, of course, not those nice power-of-two gigabytes we had when I was young).

As to why such a strange number, I suspect it has something to do with the multi level cell (MLC) arrangement, where more than one bit is stored per flash cell by setting it to different voltages. After all if (say) 0V=0 and 5V=1, why shouldn't 2.5V = [a distinctly different state] so that two cells can store three bits? I suspect the 400GB cards were an interim version that were originally designed to be 512GB but the umpteen-voltage-states-per-cell-detector didn't work quite well enough. Just guessing, though.

After a while I replaced the 400GB card with a 512GB version, which is happily sitting in my phone and letting me annoy the kids by showing them I have over 320GB of free space. I really must get round to downloading some 'educational' movies to fill the space...
