Actually i have a 4 disk dock loaded to 10tb mostly small files. But the question remains is esata supported and how to get it running. When i hook it up, the wrt doesnt see it but windows does when i plug it into a laptop. Original linksys fw supports it.
Since nobody else confirmed...
I ordered an external enclosure several months ago (SINGLE-DISK). It has both ESATA and USB 3.0. Both ports worked with whatever version DD that was on my WRT-1900ACSv2. I tested to see if one was superior speed-wise to the other. They both measured almost exactly the same. Writes were faster on the ESATA port but Reads were faster on the USB 3.0 port. So my drive is hooked to the USB 3.0 port and I use the ESATA port to power the external fan I have cooling the router.
So using the ESATA port connected to a SINGLE DISK ESATA drive worked for me with whatever version of DD it was at the time. _________________ WRT1900ACSv2
After seeing Doug's post it sparked my curiosity to see if the ESATA had actually stopped working with the newer version.
I powered everything down. (Including the drive). I unplugged the USB Cable and instead used the ESATA cable pluggining it into the drive and to my WRT1900ACSv2. Powered everything up. Drive appeared to be reading.
Once it stopped flashing I went to to one of my computers. I could immediately see the drive. I could explore the files. I tested the Samba transfer speed with the ESATA. Read speed varied 98 to 103 MBps. Write Speed varied 106 to 109 MBps. I also tested DLNA. DLNA also worked fine streaming music to one of my Internet Radios. So for me with the router and drive I am using ESATA does work. The Read speed is slightly slower than using the USB 3.0 port but the Write speed is slightly faster than the USB 3.0 port.
The Drive enclosure I am using is the
ROSEWILL RX304-APU3-35B (1TB Seagate Barracuda Drive formatted to EXT4). This is using DD-WRT R37961. My system used to test was a Windows 10 Pro 1803 32-bit system. _________________ WRT1900ACSv2
You are right d0ug, Esata is the same as sata only a different connecter and shielded cable.
If you look at the pin voltages and signal layouts they are identical and could very well be connected with a simple bread board.
I know on mine sometimes drives don't show up because they have some weird partition info and linux can't read it, or the kernel modules are way outdated.
