What do you think will be the lowest capacity used for 3D NAND SSDs?

Currently, various Chinese 60GB 2.5" SSDs using Silicon SM2246XT and MLC NAND appear to make up the capacity floor for commonly found planar NAND.

The Kingfast 32GB F6 2.5" SSD (using Jmicron JMF608 controller and MLC NAND) also appears to be surprisingly popular, although it is nowhere as common as the 60GB SSDs.

So with those mentioned, what do you think will be the capacity floor for 3D NAND?

48GB? 60GB?

In what form factors?

Using what controllers?

Some benchmarks on the SSDs I mentioned in the opening post:

The lowest capacity will likely be 120GB, with a dual channel controller most likely SMI or Phision ans two 60GB dies.

With Windows x86 devices being unable to use UFS 2.0 at this time, I have been wondering if someone will make a 64GB BGA PCIe 3.0 x 2 SSD using a dram-less controller like the Marvell 88NV1160?

With 128GB PCIe 3.0 x 4 SSDs being capable of 2000+ MB/s sequential reads, I am hoping such a device would be capable of 1000+ MB/s sequential read. However, I don't how fast the 3D TLC would be (on sequential read) compared to the planar MLC NAND the 2000+ MB/s 128GB PCIe 3.0 x 4 SSDs use?
