Western Digital has announced a 12 terabyte helium-filled hard disk drive, as well as an upcoming 14 TB shingled magnetic recording HDD. The 3.5" 12 TB drive contains a whopping eight 1.5 TB platters, and does not use shingling:
HGST's Ultrastar He12 HDDs use speedy PMR (Perpendicular Magnetic Recording) technology in tandem with eight platters to provide a beefy 12TB of capacity. The 7,200-RPM HDD provides solid performance measurements of 243 MiB/s of sustained sequential performance and 390/186 read/write IOPS at QD32. The helium-infused HelioSeal design allows the drive to scale to eight platters and provides a 2.5 million hour MTBF. [...] The hits don't stop at 12TB; the company also has a 14TB SMR (Shingled Magnetic Recording) HDD on its immediate roadmap.
WD also announced an Ultrastar 8TB SN200 SSD, and confirmed that it is working on QLC NAND SSDs that store four bits per cell. Micron also announced an 8 TB (7680 GB) SSD this week.

Western Digital got into the SSD market late, by buying SiliconSystems for their first (largely ignored) offerings, and then buying SanDisk [anandtech.com] for this offering.
I'm not sure I'd be comfortable investing that much money into a four bits per cell technology due to the performance and longevity issues. [techtarget.com]
They only offer a three year warranty as long as you keep the writes under some fairly small multiple of the total capacity. (Some others offer 10 years and vastly larger write endurance).
No, you are mistaken. I've always had this sig.

Toshiba and others are investing in QLC. Like with MLC/TLC, 3d/vertical NAND allows you to blow past the endurance issues like they are nothing (larger nm sizes, ability to scale by adding more layers, and massive overprovisioning). 3D/vertical NAND has saved the NAND industry and put it on a collision course with HDDs.

3D vertical simply allows a smaller package. it has nothing to do with durability or read/write errors. (It literally means they are stacking discrete chips on top of each other in a single package - no magic there).
Bits per cell speaks to the actual storage technology. More is NOT better. Its cheaper, and less reliable, and less durable. Two bits per cell is what the 10 year warranty products are all using.

I already explained how 3D/vertical allows better drive endurance despite the use of TLC. Reread the post.
More bits per cell can be cost effective despite reliability issues, or there would be no attempt to move past TLC. Now we can see that several companies are developing QLC (and not just for low write scenarios like camera SD cards). Obviously, the drives will end up being 3D QLC.
A 5 year warranty should be more than good enough for most users. A drive with that kind of warranty could last much longer than that.

Testing suggests that the longevity concerns about TLC are overblown [techreport.com].
Granted, the sample size of 1 is way too small to be conclusive, but even the point before the wear indicator even starts to move, is well beyond typical use. My own 840 (also 250GB) is sitting at 7.5TB after just over 2.5 years of daily use. Their test unit didn't start retiring sectors until past 100TB, which would take me 40 years at this rate.

Agreed. My OCZ Agility2 is now at around 20TB writes after 7 years (half of that without TRIM), I expect to retire that drive because it will be too small/slow before it even touches reserve blocks. I've had many mechanical drives fail in the same amount of time.
