Odroid NAS died, Trying a Raspberry pi 4

My Odroid died over the weekend. It's been running every day for 4 years so, I guess it did OK doing what it wasn't really meant to do.


So I'll use something else not meant to do it again :D
This time a Raspberry Pi 4. USB 3 and gigabit ethernet.

Using the Pi's Wifi:

2 runs showing this will generally be ~80 Mbps, so I can expect about 10 megabytes per second. It's not great, though it will handle HD videos (ish).
Benchmarking the wireless has not been great - so I'll have to hook it up to my router via gigabit ethernet.



Using the Pi's ethernet to my router, then over AC wifi:
Hooked up to my AC router, via gigabit ethernet, my PC over AC is getting much better bandwidth.

My HTPC is directly connected to the same router via cable, so pure wired numbers look excellent.
Downloading files are near 50MB/s so this is quite nice.



Using the Pi's purely over gigabit ethernet:

Now we're talking. This should be good for ~115MBps



Bottleneck - harddrive:

pi@raspberrypi:~/shares/major $ dd if=/dev/zero of=./testfile bs=1000M count=1 oflag=direct
1+0 records in
1+0 records out
1048576000 bytes (1.0 GB, 1000 MiB) copied, 10.8304 s, 96.8 MB/s
pi@raspberrypi:~/shares/major $  dd if=./testfile of=/dev/null bs=1000M count=1
1+0 records in
1+0 records out
1048576000 bytes (1.0 GB, 1000 MiB) copied, 8.92268 s, 118 MB/s


These are directly on the pi, so they give a decent indication of that USB 3 capability with harddrive storage. It's not far off from the gigabit throughput so it's well matched. The numbers are actually slightly better than the odroid, which is excellent.
