Thanks Gerry! That one looks promising.<BR>
<BR>
One thing that always confuses me:<BR>
<BR>
Let's say I do software RAID. So just buy a JBOD device. It still has<BR>
some "controller" on it, correct? Is the quality of this controller<BR>
very critical or not so much? And if a unit advertises itself as<BR>
Hardware RAID can I still use it as JBOD mode? There seems more hits<BR>
for "RAID" out there than for "JBOD". Maybe I am looking up the wrong<BR>
keyword.<BR>
