Question 1

Did anybody measure the USB 3.0 or the eSATA performance?

Accepted Answer

I averaged between 600 MB/s and 625 MB/s on the USB port with a Toshiba external USB 3.0 optical drive. My MacBook Pro backup is an eSata RAID-1 with monitoring software; the monitoring software is telling me that I'm pushing 625 MB/s. One thing I've noticed is that the KTU10 tends to run on the very "warm" side with an eSata device attacked. Other than that, the Kanex KTU10 performs better than I expected.

Question 2

Does this adapter support eSata port multiplication? I am trying to connect an iMac to a drive tower with five jbod drives.

Accepted Answer

I distinctly remember it working back on Sierra with my 2012 MacBook Pro. Today on High Sierra and Mojave it's a no go. The adapter is recognized, the USB port works, but the eSATA 5 drive enclosure that used to work with it no longer does.

Question 3

Can the eSATA and USB3 ports be used simultaneously, or must they be used one at a time?

Accepted Answer

They can be both used at the same time, in fact I just copied a 10GB folder from an eSATA drive to a USB3.0 one at about 60MBps - About two minutes - (the drives are 3TB and 4TB respectively, and very full, so maybe that affected the speed performance.) There is, however, a difference in read and write speed, specially in the eSATA vs firewire800 department. (The 3TB is a FW800+eSATA Lacie Quadra) Hope it helps!

Question 4

Will this work for a elgato hd60s game recorder. my 2012 imac doesn't have usb 3.0 ?

Accepted Answer

This will take your thunderbolt port and give you USB 3.0 on you 2012 iMac. I did this to a 2011 21.5" iMac and have had absolutely zero problems. It was recognized immediately and have had no connectivity issues with a Seagate 8TB USB 3.0 HDD for movies using Plex. The HD60S does not have a USB A port. it has USB-C. You would need to get an additional USB-A to USB-C cable here on Amazon with this and it should work.

However, I'm not a gamer. the operative work is "should" you would need to check if the HD60S is interoperable with Macs. doing a quick google the 2012 iMac had Ivy Bridge CPU's which are 3rd gen CPU's for the core i* series. HD60S requires a minimum of 4th gen CPU's. YMMV but I would say it's not a good fit for your Mac.
