The jury seems to still out (at best) on the question of block vs. file.
I suspect the main issue are you NAS (file storage) or SAN (block storage):

https://blog.storagecraft.com/object-storage-systems/
https://www.linode.com/docs/platform/block-storage/block-storage-use-cases/
https://www.raidinc.com/2019/12/file-block-and-object-level-storage-which-solution-is-best-for-your-organization/
https://www.hyperconverged.org/wp-content/uploads/2019/12/why-you-need-block-storage-in-a-hyperconverged-world.pdf

If anything people seem to be recommending object over block and block over
file.... one comment if iSCSI is such clusterF then object storage is even
worse since it abstracts the physical location away where is block at least
preserves that.
