 ## Azure Cobalt 100 Arm-based processor
 
-Azure’s Cobalt 100 is Microsoft’s first-generation, in-house Arm-based processor. Built on Arm Neoverse N2, Cobalt 100 is a 64-bit CPU that delivers strong performance and energy efficiency for cloud-native, scale-out Linux workloads such as web and application servers, data analytics, open-source databases, and caching systems. Running at 3.4 GHz, Cobalt 100 allocates a dedicated physical core for each vCPU, which helps ensure consistent and predictable performance.
+Azure Cobalt 100 is Microsoft's first-generation Arm-based processor, built on Arm Neoverse N2. It allocates a dedicated physical core for each vCPU, which provides consistent and predictable performance for cloud-native, scale-out Linux workloads. These characteristics make Cobalt 100 well suited for storage-intensive applications like MinIO, where throughput and latency consistency matter.

 ## MinIO
 
-MinIO is a high-performance, S3-compatible object storage platform designed for cloud-native applications, AI/ML workloads, and modern data infrastructure. It is lightweight, scalable, and optimized for high-throughput and low-latency object storage operations.
+MinIO is an open source, Amazon S3 compatible object storage platform you can run on your own infrastructure. It supports the Amazon S3 API, so applications and SDKs written for S3 work with MinIO without modification. This makes it a practical choice when you want S3-compatible storage without cloud vendor lock-in, or when your compute and storage need to run in the same environment to avoid data transfer costs.
 
-MinIO is commonly used as a storage backend for data lakes, machine learning pipelines, backup systems, and analytics platforms. It supports the Amazon S3 API, allowing seamless integration with existing tools and SDKs that are built for AWS S3.
-
-MinIO is designed to run efficiently on Arm-based architectures such as Azure Cobalt 100, enabling cost-effective and energy-efficient storage solutions for large-scale workloads.
