Intel's Otom memory products are based on 3D Xpoint technology that Intel and Micron developed together. In 2006, Intel and Micron each invested $1.2 billion in a joint venture to develop 3D XPoint, which was first announced in 2015.
This technology has the high-speed access performance similar to DRAM, and the non-volatile performance similar to SSD. It can store data even when the power is off, and the cost is lower than DRAM. In 2017, Intel officially launched the Aoteng series of products based on 3D XPoint technology.
But that was all in the past, and it was at this particular time (having shut down the business) that Intel quietly introduced the last storage device based on 3D XPoint memory, Optane P5810X.
From the details announced, Optane P5810X comes in 400GB and 800GB versions, offering PCIe 4.0x4 interface x 1, and the overall focus is on durability.
The 800GB continuous write speed of P5810X is 5400MBps, while the 400GB is 6000MBps. Meanwhile, the corresponding express speed under the read/write delay of 5 microseconds is 1.5M/1.38M IOPS. It has no problem to maintain 40000GB write every day for 5 consecutive years, and its durability is not questioned.
As for why not mention the price, please refer to the general price of P5800X, 400G is 6500 yuan, 800G is 13000yuan, 1.6T and 3.2T are 24600 and 49900 respectively.
Finally, Intel will incur a $559 million loss when it shuts down Otum, which is the entire division, not just Otum memory products.
