We tested the DS920+ with a number of scenario’s that it may face in the real world. The settings for these scenarios are as follows.
512MB file size, 16KB Block size, 80% Read 20% Write 100% Random, I/O queue depth 128
1GB file size, 16KB Block size, 100% Read 0% Write 100% Random, I/O queue depth 64
Transfer Size: 8K Reads: 80% Writes: 20% Random: 80% Boundary: 8K Outstanding IO: 64 Threads/Workers 4
2GB file size, 4KB Block size, 90% Read 10% Write, 90% Random, 10% Sequential, I/O queue depth 128
160GB file size, 64K Block size, 98% Read 2% Write, 100% Sequential, Boundary: 4K, I/O depth 64, Threads/Workers: 8

We also tested the DS918+ in a few scenarios it might be used for in an office environment. It produced average bandwidth speeds of 137.35MB/s and 112.01MB/s for the File Server and Web Server tests respectively, 50.22MB/s for the Workstation test and 112.43MB/s when tested with the Database trace.
