Opps, didn't read the RAID-0 bit, still try the GPT stuff, the 2TB MBR is a
hard limit.  gstripe(8) would also be an option.  With you're RAID-0, were
you looking of for read or write speed?  You can still use RAIDZ and
outperform a straight stripe in most workloads if you make use of an ssd
based L2ARC and a ZIL for read and writes respectively.
