To test the DiskStation DS918+ we used four WD 6TB Red drives (WD60EFRX, 5,400rpm class, 64MB cache), built into all the RAID arrays supported by the device; RAID 0,1, 5,6 and 10 using the default Btrfs file system and then tested.
Atto Disk Benchmark.
To test real life file/folder performance we use a number of different file/folder combinations to test the read and write performance of the NAS device. Using the FastCopy utility to get a MB/s and time taken for each transfer, the data is written from and read back to a 240GB SSD.
