Micron revealed performance data of working SSDs based on 3D XPoint memory at the recent Flash Memory Summit. Separately, rival Toshiba showed progress on conventional NAND flash, and mega-customer Facebook called for multiple new kinds of memory products.

A Micron engineer showed prototype SSDs with XPoint memory chips on a PCIe Gen 3 interface handling writes at less than 20ms and reads at less than 10ms, 10 times faster than existing NAND SSDs. Devices using four PCIe channels delivered up to 900,000 I/O operations per second. SSDs using eight-lane PCIe peaked at 1.9 million IOPs.

Overall, Micron promised the drives it will brand as QuantX will deliver four times the capacity of DRAM. Compared to NAND, it will offer 10 times lower latency and 10 times higher IOPS at up to 32 queues.

The company showed data on XPoint SSDs at densities from 200 to 1,600GB. However, it did not announce availability or pricing for the drives or the chips based on them.
