Solved Best Spanning Enclosure

I'm looking to purchase an external enclosure for spanning. The 2 enclosures I'm trying to decide between are the StarTech SAT3520U3R and the SANS DIGITAL MobileRAID MR2UT+B. I'm pretty sure both will work for my needs, I just want to get the one that will work the best, be more durable, and with the least amount of headaches. The bonus of both of these are USB 3.0. The Sans Digital is more expensive... but if it's worth the extra $$, then I'll get it. If anyone out there has either of these or has knowledge of either and can help me out, I'd really appreciate it. Thanks!

After tons of research, I went with the Sans Digital. The unit arrived today and seems very well made. I will be posting a question on here about spanning 2 hard drives. Hopefully, someone will help out. Thanks...
