Hello,
I request a slice with a default disk space setting, 10GB. I checked the github but didn’t find out that the storage class. I was wondering if the node storage type was SSD or NVME? Also, How could we apply for a different storage class when we create a slice.
Thanks,
Best Regards,

The default storage in one of your VMs is a virtual block device attached to the VM and mapped to the VM’s host’s local disk. The host’s local physical disk is an SSD (i.e. not an NVMe drive). The performance of these virtual block devices is a bit difficult to assess because the virtualization is optimizing a lot of things for you.
Some things that will affect the performance of your local disk:
dd
command you can add oflag=direct
and it will skip this cache.If you want to use an NVMe drive you need to add an NVMe drive component to your VM (like how you add an NIC component). Checkout the NVMe examples listed the in the “start here” Jupyter example notebook.

Thank you so much! That definitely helps a lot.
