Intel Aoteng 3D XPoint flash memory shows the ferocious random read and write performance. Among them, the Optane DC P4800X has the maximum random read and write IOPS of 550K/500K, and the read and write latency is 10us, which is several times the speed of current SSD products, while the continuous read and write speed is 2.4/2GB/s, providing two capacities of 350GB and 750GB.

As a brother in the SSD field, Samsung presented its first Z-NAND product, SZ985, on November 20. The core selling point is low latency. Compared with PM1725a, it can achieve three times the throughput and 1/3 the latency. PCI-E 3.0x4 interface, HHHL half height half length PCI-E card specification. The continuous read/write speed reaches 3.2GB/s, and the maximum random read IOPS is 750K, both of which exceed Aoteng flash memory. However, random writing is only 170K, reading delay is 12-20us, and writing delay is 16us. For the time being, only 800G capacity is available, and the durability is 30 DWPD.

The performance of the SZ985 is excellent enough, but the main problem is the price, just like Aoteng. You should know that the price of the 350GB P4800X is 1520 dollars, leaving the price range of the SZ985 relatively "broad".
