Instead of a box, the Hellfire comes packaged in a cardboard blister pack. The packaging advertises many of the drive's key features including its capacity, PCIe Gen3x4 interface, NVMe 1.2 support and three year warranty.
The Hellfire uses the 2280 form factor for M.2 (NGFF) SSDs. It measures 22 x 80 x 3.8 mm and tips the scales at a mere 9g. The drive also has an "M key" edge connector which provides PCIe SSDs with up to 4x lanes of bandwidth.
The Hellfire uses Phison's PS5007-E7 controller chip. This 8 channel, PCIe Gen 3 x4 SSD controller is powered by a quad-core CPU and offers support for SLC, MLC, TLC and 3D NAND flash. The PS5007-E7 also includes features like end-to-end data path protection, SmartECC RAID data protection, power loss protection with additional SmartFlush technology and advanced read disturb management with SmartRefresh technology.
For the 240GB version of the Hellfire, Patriot has opted to use Toshiba's 15nm MLC NAND flash. Looking at the pictures above, you can see that there are two 64GB NAND flash packages on either side of the PCB. The drive also has a single 256MB NANYA DDR3 memory chip that is used for caching.
