In my new 5950x build, I have a Crucial P1 500 GB NVMe as my boot drive....with pretty much stock BIOS settings, I was getting about 1700/900 read/write speeds in Crystal Disk...

I installed Crucial's Storage Executive software and turned on Momentum cache and the speeds jumped up to this...

What type of sorcery is being used here? Is there any reason to not keep this enabled? Other than my PC is not on a UPS?

That Momentum cache will use some of your system ram to speed up the P1 500 GB NVMe There is also a chance that it can corrupt the stored text on your drive so beware.

It's useful to see big numbers benchmarking the drive, but outside of that you won't see any real world benefit. It's the same kind of program that Samsung offers with their Rapid setting.

As alluded to, Momentum Cache uses your System RAM as a Read and Write Cache. That last part is important, as it increases your read / write rates substantially, however, if your system is writing data and your system loses power, freezes, etc, the data that the filesystem is committed may not actually be committed to stable storage (your SSD). As such, you can end up with an unusable system that you’ll need to restore from Backup.

TL;DR, only use the feature if you’re willing to restore from backup, as there’s always a chance a bad freeze-up or power loss will destroy your file system.

Those are just fancy benchmark numbers and mean absolutely 0 anything for real-world performance. This is a post that I usually type to people who boast about the same performance increase from Samsung's RAPID, the same exact concept applies here. You cannot defy the laws of physics, you are just under the illusion that it's faster, when in reality, when you do a file transfer, everything is just being done hidden in the background (no offense):

If you turn on RAPID mode, you are not benchmarking your SSD anymore, you are benchmarking your RAM.

Translate that into real-world performance and it means absolutely nothing.

For example, test this.....

Copy a huge 10GB + video file or whatever large file you want from your C: partition to another partition on another disk......

You will notice that the Windows file copy progress finishes insanely fast.....the moment it finishes the copy, I want you to restart your system

then check that file you copied, it would be corrupt, reason is, yes the file copy progress finished fast, but it didn't finish really, all it was doing is copying the file from your SSD to the RAM Cache and not the actual 2nd SSD or HDD you were intending to copy to, then after it goes to your RAM Cache using RAPID, it is supposed to copy from the RAM Cache onto the actual disk in the background which didn't happen in this test I did since I restarted immediately after the fake file transfer progress was finished.

so it's just cheating + placebo effect

And after you read this, you will never enable RAPID again.....it will actually make your performance worse not better
