[SOLVED] Do you lose speed Partitioning NVME and What is Cache Enhancement for NVME SSDs

[edo101]

Hi all, I just got a WD SN750. First time ever using an NVME. I was looking at the reviews and the top review, the guy was getting record seq read writes:

He attributed it to 4GB Ram Cache enhancement. I wanted to see if you guys know what this is? If it makes much of a difference and if so, how to implement it?

That is using part of your RAM as a cache for your storage device.
It has many names. For instance, with a Samsung drive, they call it RAPID mode.

Usually, it is just a waste of RAM space. Benchmark numbers may look huge and impressive.
User facing benefit, not so much.

Ah okay thanks @USAFRet. So I won't see any real world benefits. And for having 16GB sysytem memory, it'll just be better to leave the system to use that RAM instead of sharing it with my storage?

^ This. Waste of time, no real world benefit.

Yes.

I tried the Samsung RAPID mode. Benchmark numbers were HUGE.
I saw zero actual benefit.

We get a question about that here often.
"Why is my SATA drive so much 'faster' then my NVMe?"
'It isn't...that is just reading your RAM speed.'

Wait are you trying to tell me there are SSDs faster than NVMEs?

 

[edo101]

Also do you lose speed when you partition your NVME? I have a 1TB I am clearly partitioning for my OS and Data

No there aren't.

But use of those cache concepts make it LOOK like it is.
It is not.

No.
But why are you doing this partitioning?
And what size partitions?

I have two windows 10 installations. 1809 (for 3D compartibility) and the most current WIndows 10.
Then another partition to keep my data seperate so 3 main paritions plus the UEFI/boot partitions

Oh yes...thats right.

No, partitioning does not reduce its speed.

Thanks again as usual!!!! You've helped me a lot get modern
