Server build performance remains at 115Mb/s during operation.
Hello everyone, I set up two servers based on the Mark Rober video using Linux Tech. Writing files to them is limited to 115Mb/s, which is slower than expected since my Synology NAS offers 350Mb/s. The hardware matches the video closely: a ROMED8-2T motherboard, 16-core EPyc CPU, 128GB DDR4 RAM, a 12TB HDD spinning at 7200rpm (Seagate Exos X22 SATA), and a 6Gb/s HDD. I haven’t used TrueNAS before, so I’m checking if adjusting a setting could improve performance. Our board has two 10Gb Ethernet ports, so it shouldn’t be the bottleneck. Please assist!
They integrate with additional 10Gb ports and established a 10Gb connection. There isn't a standard Gigabit link between the client and server. The observed 115 MB/sec aligns with typical performance on a fully utilized Gigabit link.
Surprised not at all. Hard drives aren't quick, and 10Gb NICs don't really help if your storage is HDD-based... it doesn't matter what interface you use. What RAID configuration are you using? It depends on the type of RAID you have, but Synology can distribute data across multiple drives using its own RAID setup. This helps approach striping performance, though HDDs still lag behind. A 115Mb/s speed is better than a single drive transfer.
Hi, we linked them together directly and assigned fixed IP addresses to each device. We're using RaidZ2 with six HDDs, all of the same high-speed drives found in our Synology NAS. When we applied the same configuration to our existing NAS, we achieved speeds of 300-315 MB/s. Additionally, our new NAS includes a 1 TB NVMe cache drive.

So go for raid 6... basically stick to raid 5 with two failover disks unless you're using raid 0. You won't actually achieve magical speed boosts from an HDD. SAS or SATA drives are the way to go. With raid 0 you can reach up to double the speed. Keep in mind a few things: 1) Disk speeds cap around 80-150MB/s for big files. 2) Your RAID controller's bandwidth is a factor—standard Dell PC6 cards usually max out at about 300MB/s or 2400Mb/s. Bits matter more than bytes. 3) The file sizes you're dealing with play a role; lots of tiny files can slow things down, often to just 10-20MB/s. 4) Your NVMe controller matters too—SATA is limited to around 550MB/s, while PCIe can push up to 3000MB/s. There are plenty of links that can slow down the system, just like internet speeds; data transfer is always limited by the slowest part.
1. Ok, sounds good on that one. 2. 8 of our hard drives are connected straight to the motherboard using 2 SAS to SATA cables/splitters and the other 4 are connected using the same cable onto an LSI SAS 9300-16I 12GB/S SATA+SAS HBA Host Bus Adapter Card. 3. We're working with fairly large file sizes, mostly RAW video files to be edited using Premier Pro. 4. Both of the nvme drives are connected directly to the two motherboard slots. I did just figure out that my 10GB switch was auto negotiating the link speeds to 1 Gbps for some reason, so I connected directly between my tower and the NAS (which I thought I had already tried that) and our transfer speeds improved to around 315 MB/s, which is what our Synology was doing, but we were hoping for a little bit faster speeds. Thanks a lot for the help!
The main constraints are the hardware components. Using full NVMe RAID will affect performance, so I suggest a fiber 10GB fiber NIC and a Twinax cable.
