Chinese sites have released a first peak at Intel's datacenter optimized Optane drive.
The specs are as follows:
-375GB
-NVMe PCIe x4 interface
-2800MB/s read, 2000MB/s write
-550K IOPS read and 500K write random 4k
-<10us typical and <150us 99.999% latency(the latter just means worst case)
-30 DWPD endurance, 12.3PB written
-18W/5W max/typ power use
Analysis: The specs are pretty much as promised in their demos. We don't have further details like performance at QD1, but there's enough to guess quite accurately.
-Performance: 500K random write 4K = 2GB/s. That means random write performance is identical to its sequential. Remember the demo over a thunderbolt interface? https://nvworld.ru/files/news/optane-ssd-benchmarked-at-idf/optane-demo.png
I find it quite likely they'll release a consumer version as they did with 750 drives. The encouraging part is the transfer rate graph, where its an unchanging 2GB/s. The individual dies likely need more parallel channels to increase drives sequential throughput. Indeed, Micron's QuantX demonstrated that with a PCIe x8 interface, its practically at its limits with mixed random workloads at whopping 1.8 million IOPS.
-Latency: PC Perspective has made a nice graph about latency. Near worst case latency is as good or better as the best case scenario for NAND SSD. Latency could be lot better considering the underlying technology's potential. However they'll need to change the interface from NVMe to DRAM to make it happen.
-Endurance: This is going to be a disappointment to some. Its still much better, at 30DWPD. Intel's best DC drive is at 17, an average "good" DC SSD has about 10, so about 3x.
Endurance though is much dependent on yields and binning especially for such early version of the technology. DRAM version will be both much faster in throughput/latency and have endurance close to what they claim. However, there's no need to put such high quality ones for SSD and caching versions.
-Price: This bit of guess is from what I know its coming. Their datacenter "DC" line of NAND SSDs fall under the DC P3xxx naming. They'll soon update most of its NAND lines with DC P4xxx "Cliffdale" SSDs. Now what does this have to do with guessing on pricing you may ask?
Well, the top of the line P3700 is at $1.5-3/GB right now. With P4500 series, they'll have 8TB versions. That doubles the maximum capacity of their enterprise NAND SSD line, and quadruples the largest size on the P3700.
"Coldstream" Optane drives will come in capacities of up to 3TB. I would have to assume based on their naming it part of the P4xxx line as their NAND drives, pricing can be estimated. It's very possible that P4500 uses the 64-layer 2nd generation 3D NAND. It may not be entirely unreasonable to assume that the 3TB Optane and 8TB P4500 will cost similarly, with bit of a premium for the Optane drive.
Since most of its potential is capped by the interface, it would hamper sales if the pricing for the 3TB Optane is much higher than the 8TB P4500 NAND SSD.
That would mean the 375GB drive might come in the $600-700 range, the same as planar NAND P3700 400GB costs today. DRAM versions will cost likely far more per GB.
