5 out of 5 eggsPerfect Buy!!!

Pros: clone function, dual docking bay 3.0 usb speeds

Cons: have to turn entire device off to eject one drive if your using it for other ways than just setting up a hard drive and transferring data to hard drive would not suggest people get this to use it as a hot swap bay better use for data transferring only

Other Thoughts: other wise its a great buy would suggest it to any one for short tasks not long term tasks as it keeps drive spinning non stop and always uses drive and keeps it hot with each minute that passes

5 out of 5 eggsWorks for cloning SafeBoot encrypted drive

Pros: The Archgon MH-3621 worked perfectly for cloning my computer's existing encrypted hard drive to a new SSD hard drive without requiring the drive to first be unencrypted by McAfee SafeBoot or messing up the encryption.

Cons: I had to reboot the computer twice for it to behave normally after booting from the new drive. Not really an issue considering how much time it saved me.

Other Thoughts: If you need to clone a computer that has been encrypted by SafeBoot this box is a huge time saver!
1) Insert source drive into slot 1.
2) Insert destination drive into slot 2.
3) Turn on Archgon MH-3621
4) Press and hold "Clone" button for 5 seconds, release button and then wait for cloning to complete.
5) Install new drive in computer.

Yes! It's that simple to use!

5 out of 5 eggsA great product and is worth every penny!

Pros: I ordered it because it looked interesting and could help me with cloning and using its external sata drives (I do a lot of full/partial hard disk recovery). Just today I used it to clone a 250GB hard drive that I was unable to make my desktop's sata connection to recognize. Sure enough, once I plugged it in, the computer recognized it thru the USB port and saved the day and saved me hours of re-configuration! It looks well built, elegant looking and worth every penny!

Cons: NONE

3 out of 5 eggsGood at cloning, not at "being a dock"

Pros: Nice aesthetics, solid build quality, USB3, easy cloning function.

Cons: 1. No separate switch for each hard drive, like on StarTechs, which are superior to this one, if you are looking primarily for a DOCKING station. You cannot remove only one hard drive at a time (you can always try at your own risk though), without powering down the whole dock. There is only one "Kill switch." This is a real nuisance if you are running one continuous operation (like hosting) on one drive in the dock. You have to shut that down, otherwise you are risking corrupting file partition table on one of the drives.

2. There is no option for powering down inactive/passive drive, like on most of the reputable docks (Think StarTech, Thermaltake, etc). In other words, your drive RUNS/SPINS ALL THE TIME and if you got RE2 or RE3 (server type drives), they get so hot, you can fry eggs on them. I have to snap an HD cooling gear on the hard drives in this dock, to keep the heat down. It will kill your hard drives fast, if you don't. What were they thinking (must have saves costs on a processing chip).

3. If you have one drive in the dock, you can't insert second one without tripping a connection to the first. When you insert second drive (with dock on and the contacts HOT, i.e. powered on), the first drive that is running gets reset/disconnected and re-connected. If you happen to have something running on the first drive (like playing a movie, or read/write operation going on), you will get a Windows Delayed Write error, because the drive gets "uplugged" and "plugged back in." You can get the HD really messed up by this, like corrupting MFT, again. Of course, none of this is described in the manual of the dock. The only operations and guidelines described are regarding cloning function.

It is obvious that this dock was made with cloning in mind; the "docking" function was a byproduct or an afterthought.

4. When you insert 2 hard drives and switch power switch on, it only recognizes one at a time. It is a mystery how I got second one to work, but somehow you have to either unplug USB cable a few time (not just once), or do a "hot swap," jigging one drive in and out until the chip says, "Oh, you actually got 2 drives in??? - OK, here is a second one." It's always hit and miss.

I sent a request to the customer service about a week ago, with lots of questions on the function and use of this dock as a DOCK, and still got no answer. Like I said there is nothing on inserting/ejecting order or procedure in the manual (other than "Use software disconnect," or "Press Eject button to remove hard drive."

If I knew all of the described above, I would not have bought this item.

Other Thoughts: Lesson to take away if you decide to buy this dock (and probably any other dock by this seller "Asian First" or whatever it is:
Their dual docks have no independent power switches and no spindown/stand by function. It's an always on, getting hotter with every passing hour docking option. If you have water cooling setup that you can snap on the hard drives in this dock, then get it. Even Green Drives run ON all the time. Again, what were they thinking???

Hope this review helps you to make a better informed buying decision.

5 out of 5 eggsNice Little Tool

Pros: Very easy PC-Independent drive cloning. Used it to make backup copies of production machine system drives. If a machine goes down i can now simply load up the clone and get our operators back to work. Much easier than using software based image creation.

Cons: None that I am aware of yet.

3 out of 5 eggsMH-3621 Clone

Pros: This thing is small! Very astheticly pleasing (fits nicely on any type of desk) Runs without the aid of a PC.

Cons: Does NOT support IDE drives. I was very disappointed at this, as I purchased it to salvage files from some 22 different older drives I have collected over the years.
Although I looked into it very hard, there were no indications (online or on the box) that it would ONLY support SATA drives.

Other Thoughts: All in all, I don't think I'll be returning this thing. It's going to be very handy in the future, once I get some better equipment.
