Summary: Ideal for backup of files and folders like videos and photos, or other purpose. The fact that it is a stack of four HDD device, one might keep in mind that working from one HDD to an other one in the stack is not a good idea.
Summary: The enclosure disconnected only once when transferring files but has operated flawlessly since. I have three 3tb drives and an 80gb drive installed. All drives stay at 36 C even under load so all in all a good enclosure.
Summary: The unit worked without any issues. No setup required. I have it running on an iMac. I am enjoying the faster speeds of USB 3.0 although no where near the 5 gig/sec possibility. Currently have 2 3 terabyte drives in the unit. The unit is quite light due to being made with a fair bit of plastic.
Summary: I purchased mine 2 months ago and have 8TB installed running USB 3.0. I transferred just over 2TB of movies, music videos and music in just over 6 hrs. Now this transfer was from a Seagate Go Flex drive to the Vantec HX4. The old drive before this was 22.5 hrs. with only 1.6TB of files with USB 2.0.
