[kwlug-disc] Multi-bay docks ... 1 at a time??? [Was: Re: Linux-compatible eSATA expansion cards]

[Khalid Baheyeldin]

My dual dock can do 42GB in 25 minutes to a single drive.

The drive is a WD Green 3TB, using the dump utility (which is specific to
the ext file system), and there is compression 1.4:1

This comes to 45MB/sec (or is it 31.5MB/sec?)

See the output below:
