ho is going to host a 100TB blockchain ???

[jbreher]

we'll easily see 3-5TB hard drives being $200 at most in 10 years.

Literally not even an argument.

Especially seeing as you are only off by a pessimistic decade:

4TB. Under $200. Today.

10TB is shipping in volume, and next generation will be 14TB. Welcome to essentially free blockchain storage.

You're welcome.

With a bit of patience, I've seen external hard drives as cheap as $25 per TB (so that's $200 for an 8TB drive).

That puts the cost of storing the entire 84.5 GB blockchain today at about $0.265.

It's really getting pretty silly when people claim that the blockchain is going to get to big for anybody to be able to afford to store.

With growth of 1 MB per block, the incremental cost if hard drives never get any cheaper will be about $0.1643 per year.
That means in the year 2140 (when the last satoshi has been mined) the total cost to store the entire blockchain will be about $20.65.
If people are still using bitcoin at the turn of the millennium (the year 3000), AND if hard drives never get any cheaper, the cost to store the entire blockchain in the year 3000 will be about $162

It gets a bit more expensive (if hard drives never get any cheaper) if blocks are allowed to grow to 10 MB per block.
In that case, the incremental cost will be about $1.643 per year.  By the time the last satoshi is mined (when we are all long dead and gone) in the year 2140, people will need to spend $200 on an entire 8TB hard drive to store the full blockchain.

"SanDisk has recently announced that they have started shipping their 1GB Secure Digital (SD) flash card. Although it has slipped its expected date, it is still the first production 1GB card. Jointly developed with Sharp, it contains a unique “stackable” packaging technology which has both a low-cost and high-yield so that it can be competitively-priced. It is available immediately with a suggested retail price of $499.99"

This is from 2004. So 12 years ago. $500/gb. Do you know what $500 buys now? http://www.newegg.ca/Product/Product.aspx?Item=N82E16820233766&cm_re=512gb_flash_drive-_-20-233-766-_-Product

2 512GB usb sticks. That's 1/1000th of the price in 12 years!

Now think... in 10 years do you really think 100TB will cost much more than $100? And will the blockchain even be that big??

I remember buying 256 MB pen drives a decade ago, now I'm buying 32 GB pen drives for the same price, and they run at faster speeds than the old ones. In another ten years I'll be buying 3 TB pen drives for the same price, and there will be 30 TB pen drives available that I refuse to pay for until their price drops.
