It's iozone instead and while this 'RAID' performs poorly in the end once you exchange your thumb drive with this thing you'll most probably end up with +80MB/s NAS performance in both directions.

Yup, that's what I meant lol. So backed up all my data yesterday and last night to some other drives. This morning I reformatted the RAID drive to EXT4 through the OMV interface and started moving the files back. Getting consistent 80MB+ speeds on writing back to the drive. Larger files are even moving at 110-112MB through almost the whole file so it's damn near maxing out and I'm happy. Thanks for the help on sorting out my issue.

These things can start to throttle based on access pattern. Your two iozone tests both seemed to test an USB drive since reported values are a bit too high for SD card or eMMC (or maybe you run off a really good high capacity eMMC module)?
Anyway: the mode to test with iozone is
Code
cd /path/to/mountpoint
iozone -e -I -a -s 1000M -r 128k -r 1024k -r 16384k -i 0 -i 1
This will test sequential transfer speeds with three different block sizes (128KB, 1MB, 16MB) and will also show throttling effects if an USB thumb drives starts to heat up and then slows down after some time. That's why we test with several block sizes of increasing size since normally the larger the block size the higher the transfer speeds. If performance decreases you know the thumb drive throttles to prevent overheating.

I am using a class 10 SD card. My test drive is a USB 3.0 thumb drive formatted to ext4. The actual drive I am trying to use for this is a USB 3 ProRAID array in RAID 0 which is my current media drive attached directly to my router, but I wanted to do a few test runs with OMV before moving it over. I went ahead and mounted up the RAID drive this morning and ran the iperf test. Here are the results. The drive is currently formatted NTFS but I plan to reformat it to EXT4 when I can back everything up off of it first (usually takes about 48 hours for 6TB of data).

Still trying to figure out how to use iozone though. I found a command in another thread but not sure this is what you need? It's supposed to be writing to a usb 3.0 thumb drive.

Setting up OMV on a Rock64 1GB board using the precompiled image. Setup went fine and configured a USB drive w/ shares, users, and access. Connecting to share w/ Win 10 PC works as expected. Moved a 2GB file to the share and write speeds start at around 75MBps and after 1GB or so of the file transferring the speeds drops to about 15MBps for the rest of the file. Reading files from the drive gives me a steady 75MBps the whole way through. Thought it might be a SAMBA issue so I tried the suggestions in the SAMBA tuning threads but it did not help. I tried moving the file over w/ FTP and saw the same issue. The drop off was slower but after about 1GB of the file moving it get slower and slower until it ended up at around 20MBps when the file finished. Any thoughts on what I could be looking for?
