In the article, "6 GiB/s (600 MiB/s)  when 6 GiB/s SAS drives are attached"

Does it mean 6 GiB/s link can deliver 600 MiB/s of data ?

We have been using the 1Gbit/sec = 100MBytes/sec conversion factor for 15 years or so now. NB "B" = Bytes and "b" = bits

So a 6Gb/s link = 600MB/s (nominally)

Now will a 6Gb/s link actually deliver 600MB/s? well thats a difficult one, unlikely, but given enough disks on the bus its possible to get quite close.

You just have to realise that a single disk that has a 6Gb SAS interface will only do 200MB/s sustained speed

Typo in HP documentation SAS is currently 6Gbits/sec, which is 600MB/sec.
