Increased speed elasticsearch

Elastic Stack Elasticsearch
1

Hello
I have an ubuntu environment in which there is a 100G SSD and another hard disk size of 3 TB HDD in the 100 GB hard drive in which the system is installed and elasicsearch, but the data path refers to the 3 TB hard drive

Question:
If I increase the size of the SSD from 100 GB to 500 GB, will this increase in speed help?

No, the size makes no difference, also, your data path is on the HDD disk, this is probably your issue.

HDD can be pretty slow for Elasticsearch, the recommendation is to use SSD for better performance.

Have you checked the tune for indexing speed documentation on how to improve the performance?

Yes, I read it, but just to make sure
Look, reread it in depth
thank you

In your case, using a HDD as the data path, there is not much you can do as it can be slow per design.

Are you using Linux? If yes, which is the filesystem for the disk? ext4? xfs? Depending on the filesystem and configuration, some mount options can help a little.

I don't know what the file system is, but I'm creating the environment, so what do you advise me of the two types?

I made it ext4

And what are the mount options for the data disk of elasticsearch? Are you using noatime? This can give you a small performance boost.
