Alright. So-many people are clamming that USB is faster than eSATA. Even back in the USB 2.0 days. "eSATA was on top of the line, when considering performances or transfer rate for external storage. Even today eSATA is faster then USB 3.0.
Well. The question is. Why would someone use slower input when there is a faster one or better?You have question no013?
What yo question?

I haven't seen eSATA port on any of my boards in years. USB port is on nearly every computer made in the last 20 years (unless you're Apple). Nice to know my external 2.5" HDD and flash drives will work on nearly everything.
What does that answer have to do with the question that you quoted? The question wasn't which ports were available, it was which was port faster.
2 of the 3 boards I have at home right now have eSATA onboard, the 3rd system has a PCI-E card to provide the eSATA port.
The reliability problems of USB are not theoretical. In a previous employment I developed software to automatically copy data to an arbitrary number of disks in parallel which we used to write to thousands of USB disks. We ran into all sorts of nasty problems which in the end meant we had to checksum every file after transferring to detect corruption. Not to mention wonderful things like shoddy USB controllers that cause malfunction in other connected USB devices...The answer to the question was there if you read the question correctly or looked beyond the first sentence of the answer. eSATA also requires separate power supply which is another thing (in addition to its zero presence) that makes it inconvenient. Enormous convenience trumps slightly better benchmarks and theoretically higher reliability.
Problem that I run into with USBX is that its got great burst speed for transfer but settles down to a standard speed. eSata doesnt run into that problem. I have a NAS that has both USB3 and esata. I've tested both and the esata gives me a faster consistent speed. No burst speeds, its 1 speed and stays that way through the whole file transfer process. (tested with 30+ Gig file transfers)

My Z170 ITX board doesn't have eSATA, the 8 series board I had before it didn't have eSATA, and I have to go back to a Wolfdale board to find one. None of my cases have any ports on the front panels either and they've also been disappearing on the crappy Lenovo desktops at the office... the ones newer than 3-4 years don't have the ports on the I/O panel anymore.

Not as long as the disks in the enclosures remain SATA.The only place usb wins is ease of use/compatibility. Maybe 3.1 will win out speed wise in time.
This also depends on if USB is using USB protocol or HDD protocol. I forget the terms.Well yeah, USB 3 has almost an order-of-magnitude slower response times, which makes it fairly crappy for performance SSDs handling tons of small files. This is due the overhead of a shared bus and using the processor for I/O.
SATA protocol latency: 6us
USB3 latency: AROUND 50us.
This is the place where you can get SATA and NVMe latency numbers:

And USB3 latency analysis is found here:
https://stackoverflow.com/questions/13831008/what-is-the-minimum-latency-of-usb-3-0
But for hard drives and entry-level SSDs, USB3 is indistinguishable from eSATA.
Well. If it's on-board eSATA, and USB they are both have shared bus bottleneck, but still eSATA is the king whether it's shared or self-powered. On top of it all, eSATA 3 has max bandwidth of 6 GB/s when USB 3.0 can only reach up to 5 GB/s.
