kafka doc question/clarification regarding disk peformance

I'm a newbie reading kafka documentation

https://kafka.apache.org/documentation/#persistence says:
> the performance of linear writes on a JBOD configuration with six 7200rpm
SATA RAID-5 array is ...

I am confused.
I don't know how the configuration can be both "JBOD" and "RAID-5 array" at
the same time.

> ... about 600MB/sec ...

I strongly suspect that this is intended to be a JBOD configuration and
that the reference "RAID-5 array" should be removed from the sentence.

Pls clarify ... both for me and in the doc :)
