[H] Whitebox ESXI Esata Question

[tmservo]

Ok, here's something I've never tried but have been thinking about 
testing..

Have a whitebox ESXI that just runs basic test services for me.. Xeon 
E3-1275v2 processor, 32G, etc.  Anyway, storage right now is just a 
single SATA 2TB Re4.  No desperate data on there so I just acronis it 
off weekly.

But I'm debating this now.. getting a VMWare certified RAID controller 
is a sucky proposition in re-opening this box where it's at.  I've seen 
people report mixed results using an eSATA RAID device - which should be 
completely transparent to the OS..

Anyone try or thoughts?   I figured I might grab a mid-level RAID-1 
eSATA device and give it a go..
