It is essentially a high speed cache for your boot drive. The idea is to transfer data to the memory and access it from there instead of from your spinning hard drive. An SSD will not benefit much, since it is already fast access storage, and only the boot partition will benefit at all in a multipartition/drive system, and it will not work on a RAID volume.  So like any caching technology performance depends on what you are doing with the cache data. Boots. reads and searches are likely to benefit the most, writes not so much. The performance benefit can be dramatic for some activities, where the data is already resident in the cache, so using it to speed bootup is likely to be impressive. If your only concern is to speed up your boot process, it is cheaper than an SSD. It may require you to clean install your OS and UEFI/BIOS if it is not already present when you installed/initialized these, and of course it only works with compatible MB and Cpu.

Ok thanks a lot.  So it will be of little benefit for audio performance?

The best way to improve audio performance is to find out if you have performance that is too slow. Does your system stutter or crash with the load you will reasonably demand? If not, then nothing will improve performance in any useful degree. If it does, then you need to try to track down where the problem lies. If it is with overloading the processor, then nothing that speeds up disk access is likely to help. If it is a problem writing to a dedicated audio data drive, then you are probably better off replacing that drive with something faster. If you are using a single partition on a single drive for everything, then cache memory might help, or it might be better to add another drive.

I have Optane memory that came with my motherboard. When first launched, Optane only worked with the boot drive but that is not true anymore with the latest software and will now work with data drives and even SSD. It will speed up a hard drive dramatically with speeds egual to or greater than a SSD. My first module went belly up and had it replaced under warranty and has been solid ever since. It can be a pain to configure at first though. I use it on my samples drive.

DaGeek's info is more current than me. But to be clear, you are still going to have to choose a single drive for the optane module to cache. This would be a big deal if you already have an SSD as your boot drive, and want to use a larger spinner as a secondary drive to get better performance.

In general, caching is more beneficial when using many small files.
Using large/contiguous files (audio/video), caching is of much less benefit.

Ever wonder what Apple's "Fusion" drive is...
It's a Seagate conventional HD... with a small Optane cache.

If you need speed, best to get it at the source (the drive itself - not cache).

If I am understanding this, It isn't actually replacing ram per se, but hard drive access ?

It's caching the drive (blurring the line)

For anyone that cares, I have a 3-part series on my website called HHDD (Homemade Hybrid Disk Drives). 
 
It documents what I've done with a product called PrimoCache.  The flexible configuration of PrimoCache allows an allocation of spare RAM (I have 48GB, used about 18GB for PrimoCache) to speed up read and write operations to drives of interest.  Think of it as Optane assist implemented in RAM. 
 
I found it to be fun and effective, but since the two critical-for-speed media drives in my system are RAID-0 SSD and RAID-5 HDD, the difference was much more apparent during benchmarks than it is/was during day-to-day usage. While ATTO Disk Benchmark reports about 11,000 MBytes/sec (yes, 11GB/sec) for read/write, the AJA benchmark tops out at a a lowly 2800 Mbytes/sec or so for read/write.  In either case, the machine is snappy enough no matter what, and ... I've found no real benefit for CbB usage with PrimoCache engaged.   

CbB Win10 | Mac Pro 12-core 3.33GHz/48GB | TCL 55" 4K UHD | 480GB SSD | 6TB HDD RAID-5 array| 1.5TB SSD RAID-0 array | Midas M32 | 2x Audient ASP800 |  UAD-2 Duo PCIe | Adam A7X.
