ByteccUSB3-ESATA SuperSpeed USB 3.0 to eSATA 3Gbs Adaptor

I tried with self-powered devices (devices that include their own power converter). eSATA does not provide power so there is no choice (or expectation otherwise) on that front.Be sure the eSATA device is plugged in and powered before plugging this device into the USB port or turning on the host if it is off. When I connected (or powered) the eSATA device after turning on the host (or plugging this into its USB port if the host was already powered), this would not enumerate on the USB side. The blue light comes on, but the host does not see it.Connecting it to a eSATA optical device this device does not enumerate on the USB side, even if the eSATA device was connected and powered first. I do not see it at all with a SATA optical device connected to it -- there is no USB device showing in a port directly on the side of my PC, or in a USB3 hub.Connecting an eSATA HDD to it, then plugging this into a USB port on my hub or PC works. The USB side enumerates (as a USB storage device that seems to inherit its description from the eSATA device's manufacturer and model information). I did some basic testing as a sanity check here and it looks like it works well enough in this scenario.Unplugging or turning off the eSATA HDD/SDD does NOT cause this device to report removal or shutdown. Unplug this from the USB side BEFORE you turn off or disconnect the eSATA device, else you will probably suffer data loss, a hang, or a crash. Warn the OS first, too -- tell it to prepare for a safe removal -- to reduce risk of data loss.Since I purchased this specifically to connect an external eSATA BDXL burner to a laptop, this device does not work for me, however this device is inexpensive enough that I plan to keep it around should I need to connect an eSATA HDD or SDD enclousure to the machine.

I needed to hookup a Fantom 2TB Green Drive (eSata or USB 2.0) to my Mac Mini. When reading reviews of comparable products, this one seemed to have the best compatibility and reported to have good eSata performance. However, I found that this had a side effect but I am not sure if I can blame this adapter or the Mac Mini but I concluded that it is probably both.Good: I followed the directions of turning on the drive and then hooking up the USB connection and the drive was recognized immediately by the Mac Mini running Yosemite. I was able to format the drive and used it immediately. I am using this setup as a Time Machine backup with OSX server and the backup.Bad: I have a bluetooth keyboard and trackpad and I noticed the range and usability was radically worse. The trackpad was constantly connecting and the mouse portion was intermittent and not usable unless I moved within 3 or 4 feet and even then it wasn't good. I googled around and found that the Mac Mini is not shielded adequately for USB3 noise. I ended up ordering from OWC a shielding kit for $4.99 to put some copper around the bluetooth module to limit the EMI noise from USB 3 devices. I would note that you have to literally take apart the Mac Mini to put the shield in but this isn't the BYTECC problem. However, I decided to move the drive enclosure 6 feet down on another shelf and then as a quick workaround I decided to put some aluminum foil around the Bytecc USB3-Esata adapter to limit the EMI noise around this device. Instantly, the bluetooth keyboard and trackpad worked at great range. So, I concluded that there is probably not a lot of shielding on this adapter and there is enough noise to screw up a badly shielded mac mini late (2012). I will put the shield on the mac mini and will order a ferrite core around the cable portion of the adapter to limit the noise as a long term solution. I will repost if those two thing adequately reduce the noise.Update Jan 2016: I was running solidly for 1 year of doing backups with a 3M eSata cable with aluminum foil from the usb 3 connector to a few inches past the esata connector on the estata cable. I could not get the 6M eSata cable to reliably run. I got another larger and faster USB3.0 drive and removed this old hard drive and connector from the mac mini. I plugged this same setup into the back of my Apple Extreme Router instead and I found that the drive actually worked. The Apple Extreme is a router with a USB 2.0 port that you can attach a hard drive to make it look like a a Apple Time Machine module. I don't know the performance of the drive in this configuration but it seems to run faster from my iMAC to the router with this setup than to the mac mini connected to a USB 3.0 port. I don't have any real evidence of it but maybe I can figure out how to compare the speeds.Note: While the hard drive was solid ; I did notice a shorter bluetooth range for my keyboard and trackpad with the Bytecc plugged in but it was 20 ft vs 30 ft. Sometimes when I rebooted my system the keyboard wouldn't be recognized and I had to unplug the Bytecc and connect the keyboard and then plug the bytecc (harddrive) in. I would say that was 1 out of 10 reboots. I reboot about 1 or 2 times a month so it wasn't that many times.

I like this little blue adapter for the following reasons:1. Design is sleek.2. Has an amber "activity light" for when esata drive is in use.3. Lives up to its 3 Gbs transfer speed specs.However, I don't like the following about this adapter:1. She burns VERY hot! Meaning: (Almost) TOO hot to the touch.2. Because of the heating issue, I'm also worried that this adapter will break down sooner rather than later, and that would be awful because - well, these babies aren't exactly "cheap."3. My adapter has increasingly been DISCONNECTING from its esata drive. Meaning, I lose the drive completely from Windows 7, having to restart the drive or, worst case: reboot the laptop (an ASUS Intel Core i7 Q720 1.60 Ghz Turbo). THIS problem may well be a result of the adapter OVERHEATING (see above) or ... possibly a glitch in my USB 3.0 4-port hub (manufacturer: J-Tech Digital).I need to test this "little blue genie" with a DIFFERENT hub before I can make a stronger assertion that it's definitely the ADAPTER causing the esata drive disconnect and NOT the hub. Because ... The overheating issue may ALSO be a result of the USB 3.0 hub and NOT the adapter itself. Lots of questions and I don't see too many other reviewers complaining about their adapter overheating. So, my own "diagnostic jury" is still in recess. Hence 4 Stars for this adapter (for now); to err on the conservative side, even though I'd LOVE to award her 5 (due to one VERY "cool blue" DESIGN).
