Does anyone know how to do shared folders on windows 10 that can utilize 10G networking? I have an 4 drive SSD raid 0 array (drive M:) on a threadripper pro machine running windows 10 (Premiere Pro rig). I get awesome speeds when writing locally and 300-600 MB/s speeds when copying from that array to a Synology NAS. I made that media array drive m:\ a shared folder. When I try to access it from another similar machine on the 10G network I get only 60MB/s copy speeds even though the Synology NAS works at normal speeds on that machine on the same network. What am I doing wrong? The array seems to be working fine locally in windows. I tried sharing a folder on the C drive (Rocket 4 plus 1TB) and got the same slow results of 30-60MB/s.
Ok, let me get rid of some unnecessary information here and provide an update with the solution I found. The presence of the 4 drive RAID0 array of Rocket 4 Plus 4TB drives or NAS performance don’t seem to be relevant.
VIDSRV-001 and VIDSRV-002 each have a Rocket 4 Plus 1TB SSD system drive.
The two threadripper pro machines are almost identical with two exceptions
VIDSRV-001 has a 5975WX processor with RAIDXPert and a 4 drive RAID0 array of 4 Rocket 4 Plus 4TB drives.
VIDSRV-002 has a 3955WX processor and raid is disabled.
I created a folder C:\share on each machine and shared the folder. I am using Teracopy for file copy and speed testing. Copying a 5.9 GB video file for these tests. The system drive is just a simple single drive.
On VIDSRV-001
Type 1 Copy from \VIDSRV-001\share to \VIDSRV-001\share yields around 200MB/s
Type 2 Copy from \VIDSRV-002\share to \VIDSRV-001\share yields around 500MB/s
On VIDSRV-002
Type 1 Copy from \VIDSRV-001\share to \VIDSRV-002\share yields around 60MB/s
Type 2 Copy from \VIDSRV-002\share to \VIDSRV-001\share yields around 500MB/s
There is an ethernet link involved that seems to only run at 5G speed instead of 10G but that is shouldn’t be causing a problem like this and is probably why I am seeing 500 as the faster limit right? WRONG!!! VIDSRV-002 is connected to the switches with one 35ft CAT6 cable that plugs in to a CAT6 wall jack to patch panel. There was a short home made cable from the patch panel to the switch. I replaced the flakey 35ft cable from the computer to the wall plug and all of a sudden that link was running at 10G. Type 1 copy jobs then were able to run at 300mbps from VIDSRV-002. Replacing the short field terminated CAT6 cable with a new short factory CAT6 cable then increased the Type 1 copy to 500mbps.
I now have it functioning with equal speed both directions with just some different cables. Apparently cable quality can effect 10G performance even when the link speed claims to be operating at 10G speeds.
