Disk speed test (free, not black magic)?

[CavemanMike]

I'm trying to test the speed of my synology DS214 with my macbook retina 2013. I tried blackmagic disk speed test from the app store but it generates an error.

Ny other free alternatives? I'm not a professional benchmarker; I just want to get a ball park 1 time idea of how fast this is going.

Any suggestions would be very much appreciated.

Thanks,
Mike

xbench has some disk benchmark tests included in their suite of benchmarks. Check them out.

You could always just copy files and watch your network activity.

Yes

Ultimately, that's exactly what I did:

Here's the significant result:

Single large file xfer done via ethernet to NAS: 848 mb/sec.
Single large file xfer done via Wifi AC (connect rate 878) to NAS: 426 mb/sec.

So, the bottle neck is the wifi, not the NAS. I don't need a SSD to SSD xfer.

So, the question remains is 426 mb/sec representative of three streams of wifi AC?

Thanks,
Mike
