Forget the 60 TB SSD. Toshiba is teasing a possible 100 TB SSD:
The Flash Memory Summit saw Toshiba deliver a presentation about quad level cell (QLC) technology – adding substantially to the prospect of a product being delivered in the "near future". We have heard about this QLC (4bits/cell NAND technology) quite recently.
After Seagate tantalised us with a 60TB SSD, along comes Toshiba with a 100TB QLC SSD concept.
Flash Memory Summit attendees saw Toshiba presenters put flesh on the bones and envisage a QLC 3D SSD with a PCIe gen 3 interface and more than 100TB of capacity. It would have 3GB/sec sequential read bandwidth and 1GB/sec sequential write bandwidth. It would do random reading and writing at 50,000 and 14,000 IOPS respectively. The active state power consumption would be 9 watts, the same as a 3.5-inch, 8TB SATA 6Gbit/s disk drive, while the idle power consumption be less than 100 mWatts, compared to the disk drive's 8 watts.
Even if the "near future" isn't so near, or the final capacity does not end up at around 100 TB, it is still interesting to see 3D NAND technology enabling a serious push for 4-bits-per-cell NAND, which would normally face endurance issues.

These super-high capacity drives are only going to drive down the cost of drives across the board. It might take a bit, but I for one look forward to high capacity and lower prices.
:D

Putting out higher capacities with newer and denser varieties of vertical NAND is definitely how SSD prices will be driven down.
Slickdeals is down so I can't get the "good" prices, but a quick search finds that 1 TB SSDs are just under $300 (I would guess you could find it as low as $220 on sale), and 2 TB SSDs are slightly above $600. 4 TB SSD prices are still in la-la-land for now.
New generations of 3D NAND may lower $/GB as much as 30%. We can also see a clear path for 3D NAND density to double a few times (that includes an increase in layers to ~96-128, and string stacking [theregister.co.uk] to stack 2-3 dies), whereas pre-3D NAND was facing insurmountable endurance issues.

I suspect the Toshiba announcements are 10% vaporware and 90% fraudware to pay old penalty fines and stay afloat.

This is a good point. (Both are!) We're soon back to the station wagon hurtling down the road loaded with ssds.

Or, in this case, 60~100 TB!

If you divide 100TB by 4, you get 25TB in SLC mode.
That is actually very close to the number you get when dividing the Seagate 60TB tech demo by 3 to get SLC mode.

What about security of the user? What if your OS decides it wants to encrypt everything on the drive, or delete all files permanently?
What if the OS decides that the data says something against 'teh government', speaks of overthrowing the jewish puppets and putting the people back in control? Who or what is going to protect the user's data in such an event?
What if you're using the drive as a back-up and attach to the computer to transfer files and the OS says all is good, but later you find all your important data missing. That data might have been educational material to promote a world free from oppression and free from lies.
In old tech, you could tell if the OS was doing something fishy by looking at the drive light and hearing the drive being written to or read. Now you won't hear a thing and your data will be gone or uploaded or replaced with zeros.

Not sure if trolling...
Backups. Geographically separate, off-line, verified backups. (At least for your important data like encryption keys.)
Stop using proprietary software. Use Free(dom) Software [gnu.org] instead.
Back-ups must be verified. My own back-ups failed this step.
My current plan is to set up a back-up server with ZFS backed by doubly-redundant disk drives. That way, if one drive fails, the drives are still redundant. A fourth drive would be used to serialize incremental back-ups.
With full-disk encryption, you can effectively delete the data by deleting the encryption key. This will likely fit in one 4k sector. (You do have that key (or the data it is protecting) backed up, right?)
Of course, with proper back-ups, your sensitive information is more likely to be compromised. I am thinking of using public-key encryption on the portable hard-drive.
