NVMe PCIe SSD performance measurement not optimal
- Description
- There are a number of factors that may alter the performance of an NVMe PCIe SSD. Dell recommends to take basic setup measures to ensure performance optimization of these devices.
- Cause
- NVMe PCIe SSD has not been preconditioned and/or BIOS settings are not optimal.
- Solution
-
- Without preconditioning the NVMe PCIe SSD, performance measurements can be misleading as they may not reflect long-term performance of the device. Preconditioning enables flash management, which stabilizes data throughput over a period. For the Solid-State Storage Performance Test Specification, see snia.org.
- Configure the server for low latency performance. To achieve maximum performance with NVMe PCIe SSDs, change the server performance profile in the BIOS settings to Performance.
