Micron today introduced the X100 – the world’s fastest SSD, and it’s the company’s first 3D XPoint product, which makes the X100 the world’s first direct competitor to Intel Optane.

The X100 offers up to 2.5 million IOPS – “more than three times faster than today’s competitive SSD offerings,” Micron said today. But in reality there is only one competitor out there – Intel’s DC D4800X, which also uses 3D XPoint media.

The X100 provides 550,000 random read or write IOPS so Micron’s 3x faster claim is no exaggeration. Micron quotes eight microseconds for X100’s latency. This is two microseconds faster than Intel’s D4800X SSD.

According to the company the X100 has more than 9GB/sec bandwidth in read, write and mixed modes. The D4800X does up to 2.7GB/sec when reading and 2.2GB/sec when writing. By this measure the X100 looks eye-wateringly fast.

In a statement Sumit Sadana, chief business officer, said the X100 delivered “breakthrough performance improvements for applications and enabling entirely new use cases.”

Micron claims the X1000 enables two to four times the improvements in end-user experience for various applications in data centres.

The X100 has an NVMe interface running across a PCIe Gen 3 x16 lane bus.
