Phison 5012-E12 controller
The NAND ICs are driven by a Phison 5012-E12 controller. The PS5012-E12 makes use of the NVMe revision 1.3 protocol and as you have been able to notice from the SSD specifications, this controller is advertised at a very fast ~3000 MB/s (depending on volume size) across four PCIe lanes for read and write operations respectively, over a x4 PCIe Gen 3 lane connection that is. The controller can address 8 channels. It is also ready for QLC and upcoming 96-layer NAND. The controller will offer support for up to 8 TB storage as well as offering support for external Thunderbolt 3 SSDs. The PS5012-E12 is available in three versions: the 'normal' PS5012-E12 for high-end SSDs, the PS5012-E12C for mid-range devices and the PS5012-E12DC for the business market.
