Review: Very fast. - I have this device connected via eSATA to a SATA card plugged into the PC motherboard. That card is a dual port eSATA card and it does support port multiplier, because of this Win11 on my PC does in fact see both drives. This is a good configuration for me. This device is an excellent match with the eSATA/SATA card I am using which is PEXESAT3221. Of course it is for a PCIe motherboard slot. If you are thinking of doing this make sure you have an open PCIe slot on your motherboard and if so get both. They will work perfectly and in this configuration they support RAID zero, which is what I was looking for. I hope this helps you.
Review: Power button is idiotic, no cloning, and too expensive. Otherwise, it's fine. - MAJOR FLAW - if the power goes out, you have to be on site to physically press the power button (unlike most docks which have a rocker or toggle switch in the back. This is for a boot drive for a local media server, so that's a real pain. Minor "flaw" - it doesn't include a stand-alone cloning feature. That's not so bad but then why does it cost twice as much as other docks with both (A) cloning and (B) an eSATA connector in addition to USB 3.0. That being said, I was happy to see that I could in fact connect the eSATA to the motherboard the way you'd connect the boot drive and the drive inside works just fine. Considering SATA only allows one drive (unlike old-timey ATA ribbon cables, or "PATA" as you kids call it now) it's understandable that you can't use both drive bays at the same time. Not sure why the HDD2 slot takes precedence over the HDD1 slot when you use both this way, but that's just a curiosity, not positive or negative.

### ⭐⭐⭐⭐⭐ nice SATA III external enclosure.
*by H***1 on March 31, 2023*

I have several already but they are SATA II This one is III. That is double the Data Transfer Speed from 300 to 600 MB/s. Loving it, have Installed, Booted and ran several Linux Distros from an 2.5 SSD and runs af it were running directly from the onboard mboard SATA ports. copy data between drives. To install, test or run newer Linux Distros temporarily and not disturb the m.2 internal permanent distros, like Manjaro,OpenSuse, Fedora, Debian and ArchLinux based-like distros. I wish I had bought this one before the pandemic, price has increased but still worth it. I take SATA over USB hands down.
