if it takes 8 hours to transfer 1.45tb between the two drives, doesn't that seem long for a usb3.0 connection?

you may want to check and make sure your computer has usb3 support? mine doesn't have usb3 so esata can transfer faster.

USB 3.0 can't even come close to touching the speeds you get from Thunderbolt. On paper they look close, but in the real world, on everyday machines, Thunderbolt is king. I did my own test and I transferred 2TB in 2 hours with Thunderbolt, the same 2TB data I transferred with USB 3.0 took close to 8 hours.

The speeds were very close to the ones when my esata drive was connected direct. You will lose a little speed because of the different ways esata and usb 3.0 transfer data.

I'm getting just under 130MB/s read and write. It took under 2 hours to copy some files (around a TB) that took seven hours under USB 2.0.

This unit is only designed to copy 2 duplicate USBs from one master USB. I do not believe it is designed recognize a USB hub to take place of one of the slots to duplicate a USB. I'm attempting it now with 2 gb worth of data ... it has taken 33 minutes and is only 45% finished. It is really bogging down.

If you think you will actually get that transfer rate you will be very disappointed. I transfer a lot of media such as videos & music so I am basing my answer on my own experience. USB 2.0 averaged 30 mbps. With my probox 4 bay I moved up to around 120 mbps on both Esata & USB 3.0. I think the Esata gave me a higher more consistent average at about 120 mbps. I run my proboxs on both W7 & W8.1. Windows 8.1 runs the fastest but my probox will drop out and I will have to hit continue once the drives restart when I move large files. I try to keep my blocks smaller with W8.1 w/I7 processor, basic on board video & W7 w/ I7 processor and 2GB video card never drops out. They both start out on the high end and then slow to around 90 to 120 mbps on larger transfers. I have an 8 bay probox that gives me the same rates even when I transfer media from 2 drives within the boxes. My hard drives are Seagate 3 TB rated at 6GBS. I have a few 2TB rated the same but I have never gotten the rated transfer speed. It takes me about 2-3 minutes to move a 5GB movie. It is a whole lot faster than USB 2.0 is all I can say.

I've found that usb3 to usb3 transfers are around 100MB/s up to 170MB/s on 3Gb/s Sata Drives you won't see faster than that till you get faster devices. USB3 to internal sata 3Gb/s drives are about 50MB/s to 90MB/s, Depending on processorand drive speeds. USB3 to e-sata Is around 70 -90MB/s The Drivers that came with mine did work. and it did power my usb 2.5" drives. but not more than 1 at a time. with out using the included power cord.

Although the transfer speed will depend on USB 2 and/or the type of SATA you have (1, 2, or 3), if you have a 2.5 inch HDD which is SATA, the cable associated with this question is compatible.

You bet! USB 3.0 supports exponentially faster transfer rates, but it's also backwards compatible to work with 2.0 device connections.

It is somewhat slow. I have not tested with an HDD but it seems that transferring a 1 GB from an SD card to a USB flash drive took a little longer than 10 mins for me. It might depend on the speed of the SD card and the HDD. When I connected the SD card and the USB flash drive directly to the computer the same file transfer took about 4-5 mins. So I would say that there is a factor of 2-3 drop in speed when using this device. I used the FtpMate app on my iPad to do the transfer.

It depends on your computer and the drives enclosures attached. Only a small set of USB enclosures operate at full USB 3.0 speeds. And USB still requires the computer to manage arbitration of disk IO, which could become overwhelming if you are attempting to move files to multiple drives in parallel. In short, you should try it. But in general, if you need high & predictable IO transfer rates with low latency, such as for OLTP database IO, USB is not your best choice. If you want low-cost bulk IO, USB might be fine.

Check the pictures; I posted one that indicates Source and Target locations.Speed varies widely with the drives. Cloning 60gb SSD drives took less than 10 mins. Cloning 500GB Western Digital 3.5" hard drives takes 30-40 mins. Please note that it doesn't take any shorter/longer based upon the contents of the drive (i.e. An empty HDD will take as long to clone as a full HDD), at least in my experience.

Well, I have a test tool, that shows 233.7MB/s write and 319.0MB/s read with a SSD drive in an USB 3 enclosure via an iogear USB3 hub.Most USB sticks, or SD cards are way slower than this.The USB3 hub disconnects, when Yosemite goes to sleep. Then via eSata it copies 1.4GB in less than 5s to my backup drive, not sure, if my drive is a bottleneck, but I am happy with the speeds.

I transferred my 250G hard drive on my MacBook Pro to a 1TB drive and it took about 3.5 hours.

You can use any USB connection up to 3.0 which the drive is configured for. It also runs FW 800 with the special add on adapter. The USB connection speed is limited to the speed of you computer's port so if it is not USD 3.0, it will transfer at the lower speed based on your computer configuration. I have the 4TB version and speed is not an issue at USB 2.0.

Depends on the configuration... If you don't change the RAID setup, it should be faster than a single 4 TB drive because it distributes the writing and reading across the two drives.

I didn't see anything on the box stating that. It does work well, I use it almost daily and I haven't had any problems yet. I transfer files that are 8 -12GB's with this drive. Also it does seem work faster with the USB 2.0 computers then the 2.0 flash drives.
