We've known Samsung was working on OEM-series SSDs using their new 48-layer V-NAND, and it appears they are getting closer to shipping in volume, so here's a peek at what is to come:
First up are the SM961 and PM961. The SM and PM appear to be converging into OEM equivalents of the Samsung 'PRO' and 'EVO' retail product lines, with MLC flash present in the SM and TLC (possibly with SLC TurboWrite cache) in the PM. The SM961 has already been spotted for pre-order over at Ram City. Note that they currently list the 1TB, 512GB, and 256GB models, but at the time of this writing, all three product titles (incorrectly) state 1TB. That said, pricing appears to be well below the current 950 PRO retail for equivalent capacities.
These new parts certainly have impressive specs on paper, with the SM961 claiming a 25-50% gain over the 950 PRO in nearly all metrics thanks to 48-layer V-NAND and an updated 'Polaris' controller. We've looked at plenty of Samsung OEM units in the past, and sometimes specs differ between OEM and retail parts, but it is starting to make sense for Samsung to simply relabel a given OEM / retail part at this point (minus any vendor-requested firmware detuning, like reduced write speeds in favor of increased battery life, etc).
With that are the other two upcoming parts that do not appear on the above chart. Those will be the 960 PRO and EVO, barring any last second renaming by Samsung. Originally we were expecting Samsung to add a 1TB SKU to their 950 PRO line, but it appears they have changed gears and will now shift their 48-layer parts to the 960 series. The other big bonus here is that we should also be getting an EVO, which would mark Samsung's first retail M.2 PCIe 3.0 x4 part sporting TLC flash. That product should come in a lot closer to 850 EVO pricing, but offer significantly greater performance over the faster interface. While we don't have specs on these upcoming products, the safe bet is that they will come in very close (if not identical) to that of the aforementioned SM961 and PM961.
All of these upcoming products are based on Samsung's 48-layer V-NAND. Announced late last year, this flash has measurably reduced latency (thanks to our exclusive Latency Percentile testing) as compared to the older 32-layer parts. Given the performance improvements noted above, it seems that even more can be extracted from this new flash when connected to a sufficiently performant controller. Previous controllers may have been channel bandwidth limited on the newest flash, where Polaris can likely open up the interface to higher speed grades.
We await these upcoming launches with baited breath. It's nice to see these parts inching closer to the saturation point of quad lane PCIe 3.0. Naturally there will be more to follow here, so stay tuned!
