I guess how the drives are connected has nothing to do with raid or no-raid but to be sure I'd like to ask this short question.
I just created raid-1 on my 2x2 external USB-connected drives and now discover I could use eSATA for more speed. So I want to buy a slot plate with two connectors and two eSATA cases.
My board is ASUSTeK M4A785TD-V (5x SATA II) the disk are Samsung HD204UI (SATA II)
EDIT I use current Ubuntu and built the array with mdadm (software raid)
Should be okay, right?
