Intel Optane SSD DC P4800X – the First Commercial SSD Utilizing the 3D XPoint Memory Technology

Intel Optane is a new breakthrough in non-volatile 3D XPoint memory technology which offers incredible performance, outperforming the traditional NAND flash memory used in a regular SSD and with better endurance than today’s best NAND flash based SSDs and much higher density than DRAM, all of that at an affordable cost.

Intel Optane SSD DC P4800X is the first device which is using 3D XPoint memory technology developed by Intel and Micron, in which memory cells sit in a three-dimensional mesh. It is initially available in limited quantities now, with broad availability expected somewhere in the second half of the year.

The Intel Optane SSD DC P4800X (DC being for ‘data center’) can be used in two ways:

1. As a regular PCIe attached SSD;

2. Or, it can be used as a regular RAM, when combined with an Intel 7th gen Core CPU and an appropriate Z270 chipset, or along with upcoming X299 chipset (due in about 6 months), which allow users to increase the capacity of the physical memory in their PC or server by a large amount. Even though 3D XPoint memory technology reaches just 1% of today’s RAM speed, it might not matter to ones looking to expand the RAM capacity in their PCs or servers without spending a fortune. 3D Xpoint memory is cheaper than conventional RAM. Also, it requires far less energy to operate, so it is a perfect match for data centers and large enterprises.

The Intel Optane SSD DC P4800X has typical read or write latency under 10µs, with 550,000 random 4K read/write IOPS, compared to tens of microseconds for the today’s best NAND flash based SSDs with 100,000 random 4K read/write IOPS.

The price for a 375 GB model is $1,799.99 , and it will be offered as PCIe add-in-card and later in U.2 form factor. After 3-4 months we should expect higher capacity models: 750GB and 1.5TB PCIe add-in-cards, and same capacity models as U.2 drives. The price for the Intel Optane SSD DC P4800X 375 GB model is approximately two times the cost per gigabyte of the Intel’s high-end model: 400GB Intel SSD DC P3700.

Intel is planning to release DIMMs (dual in-line memory modules) featuring 3D XPoint memory early in the next year. Due to its relatively high price, initial primary market for Intel Optane will be enterprise users, data centers, PC enthusiasts, high-end gamers, graphics designers and others who need large amounts of fast memory.
