Seagate's new high-end SSD model "FireCuda 530". The form factor is M.2 2280, the connection interface is PCI Express 4.0 x4, the protocol is NVMe 1.4 The 2TB model tested this time also has a chip on the back. The 4TB model is also double-sided, but the 500GB/1TB model is single-sided. The latest controller "E18" jointly developed with Phison is used. Micron's 176-layer 3D TLC NAND is used for the NAND flash memory. By the way, the board surface where SKhynix's 8Gbit (1GB) DDR4-2666 chip "H5AN8G6NCJ-RVKC" was mounted one chip on each side of the board. The back of the board with the E18 controller, cache DRAM chip, and four NAND flash memory chips in the center. It has a cache DRAM chip and four NAND flash memory chips.
