The GIGABYTE AORUS Gen4 7300 uses the Phison PS5018-E18 8-channel controller with high-density 3D TLC NAND and a dedicated DDR4 DRAM cache for address mapping. Firmware is tuned to saturate the PCIe 4.0 x4 interface, pushing sequential read throughput beyond the common 7000 MB/s ceiling. The drive uses a low-profile aluminum heat spreader for better physical compatibility (PS5 compatible), supports LDPC error correction, and may run warm under sustained transfers in poor airflow conditions.
