It seems like its getting harder to find these in stock. In fact, some sites are showing them as discontinued or "not orderable". However, they still show up on the Intel site. Any idea if these are truly discontinued? Or perhaps stock is being kept low in anticipation of rolling out a successor model?
Intel DC S3710 discontinued?

It has probably something to do with the nand shortage, there are no product change notifications for the s3710 series.
I don't think Intel will release new sata ssds for write intesnive workloads as the sata interface has become the bottleneck for ssds and there are better options (sas, nvme, optane).
I wasn't aware of a NAND shortage but that might explain it.
I also agree that Intel probably isn't going to release new SATA SSDs.
However, it's interesting that overnight the 200 GB model that was "special order" on the B&H site is now listed as "discontinued". (The Intel site still links to the B&H site for that part). And shopblt.com switched the 400/800/1.2T models to "do not order" a few days ago and just dropped them completely from the site.

I believe you're right on the 3D NAND point.
I did a bit of Googling on this and stumbled across a roadmap article that has the following nugget of interest for Q2 2017:
Intel will add DC S4600/S4500-series and the entry-level DC S3110-series to its SATA-based SSD product line in the second quarter

Intel DC S4600 are out..
Intel® SSD DC S4600 Series (960GB, 2.5in SATA 6Gb/s, 3D1, TLC) Product Specifications
For the 960GB, 2.5in SATA 6Gb/s, 3D1, TLC version:
Intel® SSD DC S4600 Series (960GB, 2.5in SATA 6Gb/s, 3D1, TLC) Product Specifications
For the 960GB, 2.5in SATA 6Gb/s, 3D1, TLC version:
- Sequential Read (up to) 500 MB/s
- Sequential Write (up to) 490 MB/s
- Random Read (100% Span) 72000 IOPS
- Random Write (100% Span) 65000 IOPS
- Latency - Read 36 µs
- Latency - Write 36 µs
- Power - Active 4.8W
- Power - Idle 1.0W
Yeah, I saw these when they came out. What's interesting is that they have better latency specs than the S3710 but slower sequential read/write and random read/write. But the pricing on the S4500/S4600s is very attractive. The S3710s are apparently still available but *very* hard to find.
I'd be very curious to hear how the S4600 perform versus the S3710 as a FreeNAS SLOG. I'm guessing the better latency is more of a factor than the slower read/write but I think the latter will limit the upside provided by the better latency. Just a theory though.

Also, I've been periodically Googling and have yet to find a single S4600 performance review. I know SATA SSDs aren't as sexy as NVMe but they still have their uses. 
I dind't run any benchmarks yet, I think I can run dskspeed tomorrow and post the results.
So far it doesn't feel faster or slower than the 400gb s3710 that I have in another laptop.
