Question 1

Can this docking station be accessed with USB 2.0 connections?

Accepted Answer

Yes. The docking station will support both USB 2 and 3, but will be considerably slower on a two. That said, it still the best of the hard drive docks I've had or used. Connections are simple, and works with all SATA based drives (including SSDs).

Question 2

Is it compatible with SATA II drives?

Accepted Answer

I cannot answer your question directly from personal experience. However, according to industry specs SATA III is backward compatible with SATA I and II. The specs on this device also show the interface is SATA I/II/III compatible. I have been using this dock with all of my SATA devices from SSD to older spindle drives. I use this to recover data from computers I have upgraded to SSD and the user forgot they had data on the old drive. Very handy with the dual bays to transfer data. Hope that helps.

Question 3

Does this product support 4TB disk drives?
Can it do stand-alone copies?

Accepted Answer

Hi. I can support 4TB drives, but it is not a standalone device. It has to be connected to a computer to support copy/backup/restore functions. Does not come with software, so depending on what you want do, you'll need to get the software that supports it.

Question 4

can you clone drive with this device on or off line ?

Accepted Answer

I have not tried to, but you need to not have any files on the boot drive open.  This translates to me to necessitate a boot from DOS and perhaps Ghost or other similar programs .  So check the StarTech site for DOS USB drivers. If so you are in luck.

Question 5

Will this dock work with RAID? I'm hoping to connect two 4TB drives to a computer in a RAID array, but each needs power. To avoid having tons of power adapters, I'd like to use a single dock instead of powering each drive individually. I'm just not sure if a dock 
will cause problems with RAID.

Accepted Answer

I had a pair of drives setup with btrfs raid 1 in this dock but sadly the dock failed less than a year after purchase and the drives which were already 5+ years old are still going.
