Synology DiskStation DS416slim review

As the Synology DiskStation DS416slim supports both standard 2.5in HDD's and SSD's we tested its performance with both. Ideally, we would have used the 2.5in version of WD's Red drive but we couldn't source any so instead we used four WD Black 500GB (WD5000BPKX) drives. For SSD testing we used four Samsung SSD840DC EVO 480GB drives.

Software:
Atto Disk Benchmark.
CrystalMark 3.0.3.
IOMeter.
Intel NASPT.

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.

60GB Steam folder: 29,521 files.
50GB Files folder: 28,523  files.
12GB Movie folder: 24 files – mix of Blu-ray and 4K files.
10GB Photo folder: 621 files – mix of .png, .raw and .jpeg images.
10GB Audio folder: 1,483 files – mix of .mp3 and .flac files.
