R7800 USB 3.0 write/read performance

[cordezz]

Hello,
I am runnning Voxels V1.0.2.49SF on my R7800 and did some USB 3.0 performance tests.

My PC is connected via ethernet with the router which has two HDDs connected, one with EXT4 and one with NTFS.
When I transfer one large file from the PC to the routers HDDs via FTP the datarate reaches only about 30 MB/s, no matter if I use the EXT4 or NTFS HDD.
The same transfer via windows share to the router reaches about 40MB/s.

Shouldn't the write speed reaches about 55MB/s ( https://www.smallnetbuilder.com/wir...x4s-smart-wifi-gaming-router-reviewed?start=1 )?
Perhaps someone could verify my results on anothre R7800...

The read speed is excellent with about 100-110MB/s

I do not use the USB 3.0 ports, I use the eSATA port for my external HD.

Have you tried using the eSATA port on the R7800? My transfer rates are much better than you are listing with eSATA...

I have only USB HDDs :\

What is the specs on the HDD your using in the USB case? Speeds and such? There a 10K speed drive handy to test with by chance?
What was the spec drive the SNB used?

Below is a link to a past thread on USB write speed which I provided some data (see post #7):

It is a new WD My Passport: https://www.wdc.com/products/portable-storage/my-passport.html

Connected with my PC it makes about 100MB/s write speed. And even older HDDs go much faster then 40MB/s.

SNB just wrote that an 3.0 device was used, nothing more specific.

For me, the write speeds with the latest update is about 60-70MB/s for the write speeds. Read speeds fluctuate around 82-92MB/s. Overall these speeds with Voxel's firmware is significantly better than the stock netgear firmware. Though at times, the speeds will slow to around 40MB/s for a while or until I restart, but it takes a long time for this issue to happen, and has not really been a bother to me.

I am using a 2TB WD green drive connected via eSATA at the moment. I also keep the media server off since it is fer more convenient to map the network drive and access the files directly than it is to fumble with the DLNA.

Unfortunately I have no eSATA device for testing.
The media server or entware isn't the problem, it does not make any difference if I switch it on or off.
My R7800 is running in access point mode. But since everything else is fine, I don't want to hard reset it and test different configurations/FW-versions.

I just wonder why the R7800 test on SNB with stock Netgear FW two years ago performed better than my device with optimized Voxels FW.
