The purpose of this benchmark is to compare the performance of the Windows Server 2019 network attached storage (NAS) to the Server 2016 and the RedHat Linux 8.0 NAS server performance. The benchmark test was performed on 3 identical virtual machines installed on a physical server with 16 CPU cores and 32 GB of system memory. Each virtual server was installed on an SSD disk and configured to use 2 CPU cores and 4 GB of system memory.

The test was performed using 3 different data sets:

• Small Files - 500,000 files with the average file size from 1 KB to 10 KB.
• Medium-Sized Files - 50,000 files with the average file size from 100 KB to 1 MB.
• Large Files - 2,000 files with the average files size from 10 MB to 100 MB.

For each dataset, we have performed 4 benchmarks using 1, 2, 4 and 8 client machines via the Gigabit Ethernet network. The benchmarks were performed using the DiskBoss file management utility, which is capable of performing multi-threaded file copy, file synchronization, file delete, disk space analysis and duplicate files search operations.
