Hi,

We are in a need of order new servers for our installation.  
I am wondering about hot and warm allocators and the type of SSD.

In the [Hardware prerequisites | Elastic Cloud Enterprise Reference [3.6] | Elastic]([Hardware prerequisites | Elastic Cloud Enterprise Reference [3.6] | Elastic](https://www.elastic.co/guide/en/cloud-enterprise/current/ece-hardware-prereq.html) it only states SSD drives.

What is the suggested type. SSD-SATA 600 or NVMe (M2)?

Hi @jojsf

Since you are using ECE which means you haven't subscription, I would suggest you reach out to your account team and have the Elastic Solution Architect reach out to you and have a discussion.

Your hardware profiles will be related to your performance requirements to help balance performance and cost.

But just is a reference point Elastic Cloud in general, uses NVME SSDs for hot, for best performance, whether you require that level of performance or not would be a deeper discussion.
