Micron’s New XPoint SSD Finally Arrives

Micron X100 3D XPoint SSDAt its October Insight Conference Micron Technology finally revealed its 3D XPoint SSD, dubbed the X100.

While the company didn’t disclose too much about the device, it did brag about its speed, claiming that the X100 is the world’s fastest SSD, running three times faster than the fastest NAND flash SSDs and almost three times the speed of other XPoint SSDs.  The product is said to provide a very impressive 2.5 million IOPS for 4kB random reads at a queue depth of 1 and to support a 9GB/second bandwidth in read, write, and mixed traffic.  (NAND flash SSDs perform much better at reads than at writes due to the underlying NAND chips’ extraordinarily lopsided read and write specifications, among other quirks.)

Just as Intel has done, Micron plans to introduce storage products first, before bringing out a memory module to fit into a DIMM slot.

How did Micron achieve this impressive level of performance?  Well, in addition to Continue reading
