Percentage Used Over Time

Analysis Period:

When the "Read Percentage" input is set to 100%, the workload is ONLY performing drive 'Reads'. Since drive 'Reads' do not subtract from the drive life, the drive life is theoretically infinite.

Presets for data center workloads. This does not include an estimation of duty cycle, which varies greatly depending on use case.

The percentage of the total capability of the drive that is being used (example: at 50% duty cycle the drive is being used at half of the max rated performance). Alternatively it could mean the percentage of time per day that the drive is being used at max performance.

Block size of the I/O being transferred in KB. 4K = 4096 bytes. The total IOPS multiplied by the block size results in throughput in MB/s.

The selected drive

Estimated life of the drive given the specified workload

Number of times the entire capacity of the drive can be written to per day, over the life of the drive. Typically families of similar SSDs are rated at a certain DWPD to show the endurance over multiple capacities.

Total amount of data written (in TB) that can be written to the drive for the entire life of the drive

Number of write input / output operations per second scaled with effective duty cycle. To see full bandwidth and IOPS capability, set duty cycle to 100%. Write operations directly impact SSD endurance.

Number of input / output operations per second scaled with effective duty cycle. To see full bandwidth and IOPS capability, set duty cycle to 100%.

The Write Amplification Factor (WAF) is a numeric value that represents the additional, extraneous data writing that takes place when host data is written to SSDs. Specifically, WAF is calculated by taking the number of bytes actually written to an SSD divided by the number of bytes written as requested by the host.

When left unchecked, drive-specific default WAF values are used in the calculations. When checked, each drive will have an additional input field where you can specify a custom value for the WAF.
