64-layer flash was the great equalizer allowing Toshiba and Micron to close the performance gap on Samsung's V-NAND technology. The next step builds the stack in 96-layer formations while increasing the memory bus speed again. Today, we look at Toshiba's next-generation high-performance NVMe SSD featuring 96L memory but don't expect to find this one on Newegg soon. The XG6 will go to big box system builders first, and we may see a retail variant at a later period. The Toshiba XG6 is the replacement for the XG5 but not the upmarket XG5-P currently shipping in high-performance workstations. The new XG6 is faster than both XG5 variants but lacks an important feature many workstation-class users require, a 2-terabyte capacity model for large datasets. Since you can't buy the new Toshiba XG6 as a standalone purchase, our review will serve as a technology preview of the BiCS4 96L memory and a look at what OEM notebooks and desktops currently ship with from the factory. From time to time, we do see Toshiba OEM SSDs listed on EBay and Amazon from gray market sellers.
