   When you get your practice disks *do a capacity test*.   
      
   1) Create the array.   
   2) Fill the array with 1GB test files until it is full.   
   3) Did the array corrupt at 2.2TB worth of files ?   
      
   I could find evidence that the thing was using 28-bit LBA   
   instead of 48-bit LBA. I don't think the SATA specs even allow   
   that. All of SATA, should be in 48-bit addressing mode.   
      
   You should be *very suspicious* about this product,   
   and use test procedures appropriate for "mystery meat".
