 You can follow some best practices to reduce the frequency of such operations.
 
-- If possible, use blob or block sizes greater than 256 KiB for standard and premium storage accounts. Larger blob or block sizes automatically activate high-throughput block blobs. High-throughput block blobs provide high-performance ingest that isn't affected by partition naming.
+- If possible, use blob or block sizes greater than 4 MiB for standard storage accounts and 256 KiB for premium storage accounts. Larger blob or block sizes automatically activate high-throughput block blobs. High-throughput block blobs provide high-performance ingest that isn't affected by partition naming.
 - Examine the naming convention you use for accounts, containers, blobs, tables, and queues. Consider prefixing account, container, or blob names with a three-digit hash using a hashing function that best suits your needs.
 - If you organize your data using timestamps or numerical identifiers, make sure that you aren't using an append-only (or prepend-only) traffic pattern. These patterns aren't suitable for a range-based partitioning system. These patterns may lead to all traffic going to a single partition and limiting the system from effectively load balancing.
