-
-Starting with :minio-release:`RELEASE.2022-06-02T02-11-04Z`, MinIO implements a zero-parity erasure coded backend for single-node single-drive deployments.
-This feature allows access to :ref:`erasure coding dependent features <minio-erasure-coding>` without the requirement of multiple drives.
-This mode **requires** accessing stored objects through the S3 API, and does **not** support direct access to objects through the filesystem/POSIX interface.
-
-MinIO only starts in |SNSD| mode if the storage volume or path is empty *or* only contain files generated by a previous |SNSD| deployment.
-See the documentation on :ref:`SNSD behavior with pre-existing data <minio-snsd-pre-existing-data>` for more information.
+|SNSD| deployments use a zero-parity erasure coded backend that provides no added reliability or availability beyond what the underlying storage volume implements.

+Storage Requirements
+~~~~~~~~~~~~~~~~~~~~
+
+The following requirements summarize the :ref:`minio-hardware-checklist-storage` section of MinIO's hardware recommendations:
+
+Use Local Storage
+   Direct-Attached Storage (DAS) has significant performance and consistency advantages over networked storage (:abbr:`NAS (Network Attached Storage)`, :abbr:`SAN (Storage Area Network)`, :abbr:`NFS (Network File Storage)`).
+   MinIO strongly recommends flash storage (NVMe, SSD) for primary or "hot" data.
+
+Use XFS-Formatting for Drives
+   MinIO strongly recommends provisioning XFS formatted drives for storage.
+   MinIO uses XFS as part of internal testing and validation suites, providing additional confidence in performance and behavior at all scales.
+
+Persist Drive Mounting and Mapping Across Reboots
+   Use ``/etc/fstab`` to ensure consistent drive-to-mount mapping across node reboots.
+
+   Non-Linux Operating Systems should use the equivalent drive mount management tool.
