hdparm output from banana pi server

The question

Why did I chose a Banana pi server instead of a simple home desktop working as a storage box? This question was not only in my mind, but many of my friends asked me too.

Normally a desktop will give better performance than this ARM SOC, but that also includes more space, and money. I wanted to see how good/bad is this one compared to a desktop box I use as server (located somewhere in USA). I chose to use hdparm command to do simple testing, where I can make sense of the output.

Test on Banana Pi

[root@localhost ~]# hdparm -t /dev/sda1

/dev/sda1:
 Timing buffered disk reads: 268 MB in  3.01 seconds =  89.05 MB/sec
[root@localhost ~]# hdparm -T /dev/sda1

/dev/sda1:
 Timing cached reads:   772 MB in  2.00 seconds = 385.52 MB/sec

Test on my desktop server

[root@fedora-build ~]# hdparm -t /dev/sda1

/dev/sda1:
 Timing buffered disk reads: 434 MB in  3.01 seconds = 144.37 MB/sec
[root@fedora-build ~]# hdparm -T /dev/sda1

/dev/sda1:
 Timing cached reads:   22548 MB in  2.00 seconds = 11284.87 MB/sec

Is it too slow?

Maybe in many use cases, but not for my own backup needs.
