Is it possible to tie 2 different TR5UT+B's together in RAID 10

[yoos]

I purchased 2 Sans Digital TR5UT+B units on newegg and have 2TB seagate drives in every bay. My question is, is it possible to use RAID 10 on both units together? That is, I would like all five drives in unit 1 to be mirrored in unit 2, thus giving me 2 units with the same amount of 10TB data. If this is possible, how do I do it? Anyone know?

Thank you!

yes, you can ! but you can only use 4 drives - RAID10's HDD member need to be even.
One other note Seagate HDD with incorrect firmware Runs VERY SLOW in this box
