Total Cost of Ownership Considerations

Although mixed use SSDs carry a higher initial purchase price, their superior endurance can result in better total cost of ownership for workloads with significant write components. The reduced replacement frequency and higher performance justify the premium for appropriate use cases.

Mixed Use vs. Write-Intensive SSDs

Write-intensive SSDs offer the highest endurance ratings but at a substantial price premium. For many applications, mixed use SSDs provide sufficient write endurance at a more attractive price point, making them a cost-effective compromise.

Workload-Specific Selection Criteria

Organizations should analyze their specific I/O patterns before selecting between mixed use and write-intensive SSDs. Workloads with less than 70% write operations typically benefit from mixed use drives, while more write-heavy applications may require write-intensive models.
