5 out of 5 eggsStarTech S3520WU33ER

Pros: supports UASP
works in Window 7
works in Window 8
compact design
RAID0 works well

Cons: minor nit is that the front panel LED s/b less intense and the display narrower. definitely an overkill IMHO

Other Thoughts: using TWO seagate 4TB drives in RAID0 mode i was able to get 301/297 READ/WRITE on Windows 8. on Windows 7 i was able to get 264/262 using a Desktop rig with an Asus MOBO with Asus USB3.0 boost 'ON'

i am happy with the numbers. i am happy with this StarTech enclosure and also considering it's distant cousin - the one with the NAS capability.
