The Patriot Hellfire M.2 PCIe SSD is Patriot’s first NVMe SSD, and one of several similar products based on Phison’s E7 NVMe controller. As usual for Phison, the same drive is manufactured for many of their partners, who typically customize only the branding. Phison designs the controller, firmware, and PCB, but leaves the marketing up to their partners.
Phison’s PS5007-E7 controller is their first NVMe SSD controller, supporting a PCIe 3.0 x4 host interface and 8 channels for NAND access. The details we have on the E7 are a bit slim – some collection of ARM cores under the hood is a safe bet, but that’s it – however we do know that the E7 controller is manufactured on TSMC’s 28nm process and uses FCBGA packaging. Interestingly, it doesn’t use the kind of large heatspreader we’ve seen on competing controllers like Silicon Motion’s SM2260.
