That is a cluster of SK Hynix NAND Flash memory alongside a Phison PCIe 4.0 controller. Each of those components has a dab of thermal paste to create a strong connection to the surrounding metal.
After this teardown, the price of the 1TB Seagate Expansion Card seems fair. SK Hynix is selling a 1TB NVME SSD with read/writes of 3,500/3,200 MB per second for $135 that uses its 128-layer NAND. But that is in a larger form-factor PCIe 3.0 NVME. So it’s likely using two 500GB chips, and it definitely isn’t using the PCIe 4.0 Phison controller.
The Seagate’s $220 price makes sense when you factor in the increased performance and what is likely a custom implementation of CFexpress.
But fair price or not, $220 is a lot of money. Is it going to get more affordable in the future? It should. One of the major benefits of SK Hynix’s 128-layer NAND is that it significantly brings down productions costs. As manufacturing continues, the price of that Flash should come down quickly.
This article notes that this pci4 setup should be able to do 8GB a sec ( thereby exceeding MS stats for the speed).
