According to a report from Techpowerup.com, Zotac's new PCIe SSD is based on a Phison controller, paired up with Toshiba 10nm-class MLC NAND, which should offer sequential transfer performance of around 2GB/s. It is based on a half-height add-on card form-factor and features an integrated heatspreader and a backplate.
Hopefully Zotac will have the new PCIe SSD on display at CES 2016 so we will have a chance to see it in action.
