Intel Optane memory is basically a small amount of cache RAM installed into an M.2 form factor card.  It acts as a buffer/bridge between slower mechanical HDD's and RAM.  It's primary purpose is to help boost system responsiveness by pre-caching what the OS thinks its going to need next.

Optane in our cases is usually installed in the M.2 socket on the motherboard.  Personally I'd opt for a true NVMe drive as the primary for Windows, with the 2TB HDD for application or general storage.

And yes, Optane will work with 9th gen processors.

Think of those hybrid HDD drives that have a small amount of RAM used as cache (not to be mistaken with regular drive cache)... same principle.

I remember my friend and colleague implementing SATA's native command queuing in the 2000s. 

Hello thank you for the quick response.  Yeah I wanted to use the intel optane Memory with the hdd just to save some money and still act fast like an ssd . I'm planning on upgrade to an ssd in a year. Im Definitely going to upgrade to the 32gb hyperX fury with 1tb ssd  now like you said in the future 

Even with Optane, you're never going to get SSD performance. It might help with certain things that are constantly being read by the OS, but after a while, an HDD can only throughput at a certain rate.  Similarly, Optane is limited in terms of cache size.

@JoeSkieez, I'd advise you to be careful of this:

32gb: 16gb intel optane Memory + 16gb hyperX fury 

Another forum user just bought a system thinking that it has 32GB of RAM. That is not true. There is only 16GB of RAM while the 16GB Optane is like @amstel78 mentioned, a booster for the HDD, to make it behave like its speedy brother, the SSD. If you want 32GB RAM and fast storage, you'd want to go with 32GB HyperX fury ($$$) and 512GB/ 1TB SSD ($$$).

It's 2019, let's try not to use HDDs unless for very good reasons. If it's about cost, just cut down on the number of Steam games purchased in the next sale.

@GTS81  brother, we've come a long way since then!  My first PC was back in the 80's.  It was an 8086 IBM PC with a 10 or 15 MB MFM hard drive... maybe it was RLL.  Can't remember now.  But wow, I'm so happy to have lived through 5.25" floppies, then the invention of 3.5" discs, CD-ROMs, etc.  Back in the day, quality video games came from Sierra and you were the cool kid on the block if you had a Sound Blaster card and could play around with Dr. Sbaitso... how many people here remember that program?

Now, all the kids I know that play video games are like shooter this, shooter that!  LOL.. I did eight years in the 1st AD, 2nd BGD combat team.  Somehow shooting people in real life isn't much like the video games... although I do appreciate the advancements in graphics.

I didn't know Dr. Sbaitso but I could attest to the cool kid factor. Refer to #2 below. Who can resist the best MIDI-maker on the street when the card churns out the Airwolf song better than what was played on TV?

Started in 1988:

1. 8088 IBM PC clone + 20 MB HDD (upgrade) + 2x 5.25" + CGA monitor
2. 486DX2-66 + Aztech multimedia PC upgrade pack (4x CDROM + wavetable synthesis soundcard!)
3. Cyrix MMX PC - best left behind as a bad memory for random reboots
4. Pentium III 450 MHz - too poor for a Voodoo graphics 3D card until Sound Blaster came along with its cheap-er 3D Blaster AGP card.
5. Long series of back-to-back Dell laptop purchases from 2004 - 2018. I call that the lost decade. 

It's been a long way since then, and it's gonna be even more exciting moving forward. This Optane thing is just the tip of the iceberg.

Thanks for the info

@GTS81did you ever own one of those Turtle Beach wavetable/midi cards?  Those things were so cool. I think I had one before convincing my dad to buy a Soundblaster.  I don't know how old you are, but I was born in '78 so that oughta give you a good reference.
