What is the minimum block volume size recommended for achieving the highest throughput in a performance block volume with a 1MB block size?

The recommended minimum block volume size for achieving the highest throughput with a 1MB block size is 800 GB. This recommendation is based on the way storage systems manage data, where larger block sizes generally lead to better performance when sufficient data is written.

With a block size of 1MB, smaller volumes may not fully utilize the underlying architecture of the storage system, which is optimized for higher data throughput. By using a minimum volume size of 800 GB, you effectively ensure that numerous blocks can be handled efficiently, reducing overhead and maximizing data transfer rates. This size also helps in optimizing I/O operations, as the storage system can perform fewer, larger operations rather than many smaller ones, which increases performance.

Choosing a volume size that aligns with the underlying infrastructure's design allows users to leverage the full potential of their storage system, particularly in high-performance computing (HPC) environments where throughput is crucial for performance.
