I have a ReadyNAS 104 running latest FW 6.6.0. NAS is filled with 4 drives (2x Western Digital Red 4TB, 2x HGST 4TB) in X-Raid. During performance tests, I am getting the following speeds using NAS performancetester - Running warmup...Running a 400MB file write on 5 times...Iteration 1: 14.35 MB/secIteration 2: 13.95 MB/secIteration 3: 14.27 MB/secIteration 4: 13.96 MB/secIteration 5: 13.34 MB/sec-----------------------------Average (W): 13.97 MB/sec-----------------------------Running a 400MB file read on 5 times...Iteration 1: 16.19 MB/secIteration 2: 16.47 MB/secIteration 3: 16.34 MB/secIteration 4: 16.18 MB/secIteration 5: 15.42 MB/sec-----------------------------Average (R): 16.12 MB/sec----------------------------- Antivirus is disabled, async is enabled on the test folder, and the NAS is for the most part setup with default settings. Any suggestions on improving performance?

capaz For iperf, you may install as follow steps, 1. Make sure NAS can connect to Internet, 2. Access NAS via SSH, then run command" apt-get install iperf" 3. NAS RX test, NAS run command "iperf -s -p 5001", test client run command "iperf -c NAS_IP -i 2 -p 5001 -P 15 -t 20" TX, Test client run command "iperf -s -p 5001" NAS run command "iperf -c Test_Client_IP -i 2 -p 5001 -P 15 -t 20" for dd test, 1. Access NAS via SSH 2. Open a share in SSH, for example: cd /data/Documents" root@nas-00-00-00:~# cd /data/Documents/Write command, root@nas-00-00-00:/data/Documents# dd if=/dev/zero of=3GB bs=1024k count=3000 Read command "dd if=3GB of=/dev/null bs=1024k" Note: 3GB is test file size, please make sure it is more than your NAS memory size, if chage to 10GB, command is "dd if=/dev/zero of=10GB bs=1024k count=10000"

These are my test speeds when directly connected by CAT6 from my laptop to the NAS, slightly faster but still slower than expected. Running warmup...Running a 400MB file write on 5 times...Iteration 1: 35.17 MB/secIteration 2: 35.56 MB/secIteration 3: 35.91 MB/secIteration 4: 35.96 MB/secIteration 5: 35.81 MB/sec-----------------------------Average (W): 35.68 MB/sec-----------------------------Running a 400MB file read on 5 times...Iteration 1: 21.72 MB/secIteration 2: 21.73 MB/secIteration 3: 21.60 MB/secIteration 4: 18.20 MB/secIteration 5: 21.64 MB/sec-----------------------------Average (R): 20.98 MB/sec-----------------------------

What is the disk configuration (including RAID mode)? Is bitrot protection on? Also, how old is the data volume? There have been settings changes over the years that increase performance, but you need to build a new volume to take advantage of them. Note that NasTester speeds also depend on the laptop disk performance, since the test is a disk-to-disk transfer. Is the laptop using an SSD?

I am running RAID 5. Bitrot is disabled. Data volume is about 7 months old. However, NAS has been powered down for 99% of that time. It was setup and has not been used since. Yes, I am using an SSD on my laptop. I have also tried using my desktop and get similiar transfer speeds.

The write speeds are about correct. But your read speeds are too slow. What is your RN104's network connection? Are you using jumbo frames or NIC bonding?

Not full at all. It's basically a new volume, 99% free space

    No, I am running 6.6.0. That appears to be the latest per the firmware check. Is 6.6.1 a beta?

3xX Could you please tell me what you are using to perform these tests? You mention "NAS performancetester", but I can't find anything by that name in my searches. Maybe you have a link to it?

Thanks!
