Anandtech published The Intel Optane Memory (SSD) Preview: 32GB of Kaby Lake Caching
A quote from the article:
Last week, we took a look at Intels first product based on their 3D XPoint non-volatile memory technology: the Optane SSD DC P4800X, a record-breaking flagship enterprise SSD. Today Intel launches the first consumer product under the Optane brand: the Intel Optane Memory, a far smaller device with a price that is 20 times cheaper. Despite having "Memory" in its name, this consumer Optane Memory product is not a NVDIMM nor is it in any other way a replacement for DRAM. Instead, it is a very small (16GB or 32GB) but very fast NVMe SSD for use as a cache device in front of slower SATA storage.The Intel Optane Memory (SSD) Preview: 32GB of Kaby Lake Caching @ Anandtech
