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.

Am I reading the cycle rate on a per cell r/e? 100?! Yuck!

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.
