Optane memory, which only works on Kaby Lake and newer CPUs is primarily a waste of money if your computer has an SSD.
The idea of Optane memory was that the Optane Memory would store the operating system and the most commonly run programs in order to ensure a faster start for systems with Hard Drives (HDD). However, the amount of memory available with Optane is not that much. Usually around 16GB or 32GB – which is not a lot of memory.
The problem is: Only older systems use HDD for a boot drive. Optane memory only works with Kaby Lake or newer CPUs, and newer systems tend to have SSDs, which basically undoes the need for Optane in the first place.
For what one spends to install Optane memory, one would probably be better advised to use the money to upgrade any hard drive to an SSD.
A lot of companies are offering Optane memory in their computers, but if you are opting for an SSD Drive, especially an NVMe PCIe drive, then do not even waste your money.
This is not to say that Optane memory will not prove beneficial in the future. It may, and probably will. Only now is not the time to invest in it.
For the Same Cost, You Can Get an SSD Boot Drive
For $49, it’s possible to buy an ADATA 128GB M.2 drive, the SU800. While slightly more expensive, you get eight times more storage. For roughly $80, the 2.5-inch Kingston HyperX Fury 240 GB offers seven-and-a-half times the storage of a 32 GB Optane module.
