Toshiba XG6 review: The first SSD with 96-layer 3D-NAND!

Is Toshiba now competitive with Samsung and WD?



It's only a year since we could easily name our PCI Express SSD roundup the big Samsung party; the South Korean manufacturer's SSDs were simply too ahead of all competitors. A year later we already saw WD enter the high-end segment and now Toshiba is doing the same with the XG6. It is no coincidence that these are both manufacturers who produce both their own controllers and their own NAND - this seems to be the only way to achieve success in the SSD market in the future.

The performance that the Toshiba XG6 shows here today is very convincing. It is particularly fast in some of the writing tests, where Toshiba sometimes only has to give way to Intels Optane SSDs. These are, of course, in a totally different price segment. Only in the heavy consistency tests does the XG6 get outperformed by other high-end SSDs, but that doesn't matter much for consumer use.

All in all, we now have three high-end NVMe SSDs that rival each other: the Samsung 970 Evo, the WD Black 2018 and the Toshiba XG6. Each model has its own strengths and weaknesses, but overall they perform similarly. Coming from a situation where Samsung had exclusive rights in the high-end segment, that is obviously a very pleasant situation for the consumer. Also pleasing to consumers is that Toshiba has the potential to price the XG6 well below the competition, thanks to the implementation of its 96-layer BiCS 4 flash memory.

However, for the time being we do not know the price of the Toshiba XG6, and it seems that you will probably have to wait a few months before you can buy this SSD or any spin-off under Toshiba's consumer brand OCZ. Just before our publication, Toshiba even informed us that mass production would probably not start until early 2019. However, due to the fact that Toshiba is the first to utilize the new 96-layer NAND, they promote themselves to a full player in the high-end segment. Therefore, we give the Toshiba XG6 a Hardware.Info Innovation Award.
