Which type of disks is recommended for most workloads?

1. Standard HDD

2. Standard SSD

3. Premium SSD

4. Ultra SSD

The correct answer is: Standard SSD

The recommended type of disks for most workloads is the Standard SSD. Standard SSDs provide a good balance of performance and cost-effectiveness. They are optimized for a wide range of applications and workloads, making them suitable for scenarios that require consistent and reliable I/O operations without the need for the top-tier performance offered by Premium SSDs or Ultra SSDs. Standard SSDs are a step up from Standard HDDs, offering lower latency and higher throughput, which is beneficial for applications that require faster data access without significant investment in more expensive disk types. They also provide durability and reliability for general workloads and can handle a variety of use cases, including web servers, small to medium databases, and development environments. In contrast, Premium SSDs are designed for more demanding workloads that require high performance, such as large databases or I/O-intensive applications, making them unnecessary for typical usage scenarios where Standard SSDs can suffice. Ultra SSDs, while offering the highest performance, are tailored for extremely intensive workloads, often featuring very specific use cases that would exceed the needs of most standard applications. Thus, Standard SSDs serve as a practical choice for most users looking for reliable and efficient storage solutions.
