The Intel Optane Memory 8000p will come in two categories: 16 GB and 32 GB. Since we are not talking about DIMMs here, I have to assume that they are referring to the block size which means that this is a significant increase over the current SSD standard and will result in large SSD sizes. PCI Gen 3.0 is supported as well as the M.2 2241 and 2280. The 32 GB variant is the superior one while as the 16 GB variant offers slightly lower performance numbers. Both, however, easily outstrip mainstream SSDs on the market right now (I took the liberty of adding a comparison table at the end).
