I use this device to upgrade from 250 GB HD to 1 TB SSHD for my 2008 MacBook Pro. This is what happened:1) I opened my MacBook Pro, took the old HD out.2) Connected power cord to Inateck docking station without connecting the usb cord.3) Inserted the old 250 GB HD into slot A, and 1 TB SSHD into slot B.4) Powered the docking station on and began cloning.It took 2 1/2 hours to complete cloning 250 GB with only about 30 GB data. After installing the new SSHD, everything runs well and much faster. One big PROBLEM：there is only a 250 GB partition used, and I could not mount the remaining 750 GB or increase the size of that 250 GB without buying a $40 software app.No! I am not ready to spend $40 for re-partitioning!So, here is my plan B:1) I booted up my MacBook Pro with the old 250 GB HD in slot A of the docking station, after connecting the included USB cable. (By the way, the USB cable sucks. It connected to the USB port on my laptop so loosely that it dropped before completing the job. I wasted almo.st half an hour because of that.)2) Formatted (Apple calls it "erase") the 1 TB SSHD and got 1TB! What a surprise!3) Got a copy of trial Carbon Copy Cloner.4) Cloned everything back from the old drive to the new SSHD.My MacBook Pro comes with USB 2.0 ports. Still, it took only 20 minutes to get the job done. So much faster than offline cloning. My old MacBook Pro is now running like a new MacBook Pro with abundant of storage! Also upgraded it RAM fro 2 GB to 6 GB, I believe I have extended the life of the 2008 MacBook Pro for 10 more years!Conclusion:1) The offline cloning is only good for cloning between same size HDs, SSHDs, and SSDs. Different types can be mixed, but better the same size.2) Offline cloning takes much longer time than through computer. So, do it before going to bed. You will have a new drive ready for you the second morning.3) If you are upgrading your HD to a larger capacity, use your computer to clone. Get a free copy of cloning software. I got Carbon Copy Cloner which works fine. Maybe you can find something else too.4) If you have a bunch of computers with old, slow hard drives, this docking station is your angel! It truly makes your life much easier!5) Transferring data through USB ports is very fast. Very easy to use the docking device as a fast, unlimited external storage.6) You can always keep a cloned external hard drive. No longer worry about hard drive failure or losing data.Last words to the seller: Please get a better quality USB cable for your customers. Mine doesn't connect to any USB port firmly. It drops whenever you move your computer even by a tiny bit.

Arrived on time and worked not just flawlessly, but so easily.I had a desktop computer with a 250gb SD drive. I purchased a Samsung 1TB SD drive to upgrade it. No matter what I did I could not get the included Samsung cloning software to work. I tried to attach the target drive internally to the computer and even bought a special cable to clone through the USB port. After much Googling, nothing seemed to work. I began to suspect that my new drive was faulty.I saw this Inateck USB 3.0 to SATA Dual-Bay product could clone drives by itself, not needing the computer at all. It was on sale and I got it for around $35.00. I opened the box, read the simple directions, connected the power, inserted the clone and target drives, hit the buttons in the proper order, went to bed, and this morning put the Samsung drive in my computer. It booted up immediately and I am typing this from that computer now. It was just that simple. Drop the drives in the device, hit the buttons, and walk a way.I have not had time to test anything else the device does, but I bought it to clone and it did it hassle free. I am very happy. I am already planning on installing SD drives in our older laptops now, something I had put off for months because of the dread of complications I had experienced with that first drive above. Those laptops are going to feel like new again.Edit August 1st, 2017I posted above immediately after the cloning and successful boot up. Later I discovered that the cloning process used only 250gb of my 1tb target drive and left about 750gb unallocated, This appears to be normal. In general terms, the process took the image of my old 250gb drive, made sure there was room on my 1tb target drive, partitioned just enough space on the 1tb drive to receive the cloning, then cloned that image of the old 250gb drive to the new 1tb drive. The key word above is partitioned. The process leaves any unneeded space on your target drive unused and cannot be recognized by your operating system. That would not be a problem if I had used a 250gb target drive, but since I used a 1tb drive, that left a lot of the new drive unusable and I wanted to use all of my 1tb drive.(If you do not need the unused space on your new drive, then you are done. Enjoy your upgrade! If you would like to see how easy it is to grab all that space and use it, then keep reading.)Thankfully, this partition process appears to be normal and there are numerous free partition apps that quickly and easily reclaim the unused/unallocated space on the target drive. Having never done a cloning or worked with any partition apps I Googled around and settled on something called EaseUS Partition Master. I downloaded the free version, ran it, and through a simple graphic showed me how the space on my new drive was divided up. Since I had zero experience with any partition apps I cannot recommend EaseUS over any others. I can only say that it was simple to use and it worked.My drive was divided into six sections, one being the cloned 250gb part that included the operating system, another was the 750gb unallocated section, the rest were small recovery sections. I wanted to combine the 250 and 750 into one simple 1tb section.Unfortunately, one of those recover sections was between my 250gb section and my 750gb section. To combine any two sections into one requires they be side by side, with the section that will do the expanding on the left and the section that will be absorbed on the right. Windows operating systems cannot help you with this situation. Windows 7, 8, or 10 can only combine the two sections after they are side by side. Since that never seems to happen, using an app like EaseUS is necessary.Using a partition management app for the first time I was scared I would mess something up, until I remembered, I still had the original 250 SSD drive and even if I did mess up, I could simply reclone and start over. What a relief! So I plunged in, downloaded EaseUS, clicked a link in the app that took me to detailed instructions. I simply moved the small recovery section that was in the way to the right, by dragging it with my mouse. The hardest thing for me to figure out was how to make EaseUS accept the movement, but I finally saw that in the top left corner of the window there were symbols for Undo, Redo, and Accept. I had to click accept for the movement to take. Once I did that, my 250gb and 750gb sections were side by side. I used my mouse and dragged the bottom right corner of the 250gb section and pulled it over the 750gb section. I accepted and now I have one section with 1tb of storage available. I still have the small recovery sections also.I know, I typed a wall of words, but I wanted people to feel comfortable with this process. Upgrading a computer with a SSD is such a huge improvement that I do not want people putting it off, like I did. Now that my anxiety and research is over, I can clone by hitting some buttons and walking away. If I used a larger target SSD, then within 10 minutes I can download a partition app, install it, and reclaim the unpartitioned space with a mouse click and drag.

Good product. Very much does what is advertised. All my old hard drive are read without any problems. Though a bit costly but worth the penny.yet to check the cloning feature, though I am sure it must work too.

I bought this to try and recover data from a failing 3.5'' SATA Hard Disk. Windows was unable to detect the hard drive, and several cheap SATA-USB converters that I had tried also were also un-reliable.As a last effort before dumping the hard disk, I bought this. And guess what my hard disk was detected and I was able to recover all the valuable files. Initially I was trying to make of clone of the HDD since this one was failing and I did not expect to recover files directly from it. But in the end that was not necessary as this device was able to access the failing HDD without any issues.The build quality is top notch. It is very compact and supports both 2.5"(laptop) and 3.5"(desktop) hard disks. It also comes with a stand alone clone feature. Ie you can clone a hard disk without turning on your PCThe device has a USB 3.0 interface and it offers really good data transfer speed.I tried it on Windows 10 Home and it was detected automatically and there was no need to install any additional drivers.Now the price is on the far end, but it is worth it.PS: Read the instruction manual carefully and follow it.

Amazing productSo lightweight and does its job excellentlyGo for it
