Intel Optane 800P SSD launched for consumers:

The Optane SSD 800P series consists of two stick-shaped models designed to plug into your PC’s internal M.2 slot. Both are NVMe-class devices using two PCI Express 3.0 lanes and its providing sequential read speed of maximum upto 1,450MB per second.

On a more technical note, each “level” of 3D XPoint memory consists of memory cells connected to selectors residing at the intersection of two perpendicular wires. A memory controller can access each memory cell individually by sending a current to the wires residing above and below the memory cell. Each cell is one bit, meaning it can only store a one or zero value. But the technology itself can stack layers, building storage capacity vertically.

The 800p comes in two capacities, 58GB or 118GB, both in M.2 format. Where things take a turn for the strange is the PCIe x2 interface—it's almost like Intel looked at the performance and thought it was too close to the 900p. The 58GB model takes things a step further, since it's a bit less than half the capacity of the 118GB model but costs a bit more than half as much.

The people that need fast storage also tend to need more fast storage, and 58GB or 118GB just isn't going to cut it. If you don't need ultra-fast storage, which is most of us, then just about any modern SSD will suffice. Intel makes a point about how the 800p delivers great performance
