Still a great video! One thing of note re: Jumbo frames. If you enable Jumbo Frames on your NAS and the rest of your LAN is not 100% Jumbo, you may experience frequent disconnects, failures to connect and outright inability to use the NAS. It can be a WHOLE LOT WORSE than just 'slowing down your network'.

I have trouble playing 4k MKV files in Plex on my Nvidia Shield when I upload a file to my Synology DS920+. My setup is as follows: Synology (Plex Server) - Nvidia Shield (Plex Client) - PC (how I transfer files to Synology with SMB or NFS) are all connected to a switch via CAT6 ethernet cable. Is it normal behavior that files in Plex have an infinite loading screen if I am simultaniously uploading from my PC to the Synology? Also, will link aggregation from Synology to the switch help in this situation?

Will, I have my Eero connecting to a NETGEAR 8-Port Gigabit Ethernet Unmanaged Switch (GS108) that then goes to my NAS and feeds the 2nd and 3rd Eero. Both of those routers are connected to NETGEAR 5-Port Gigabit Ethernet Unmanaged Switch (GS305) that feed my smarthome closet which contains my various hubs and the other feeds a TV, Roku and Firestick. My question is are these Gigabit hubs sufficient for heavy home use (and the NAS) or is this slowing everything down? Would it make sense (practically and financially) to upgrade the 1st switch to something like this: NETGEAR 10-Port Gigabit/10G Ethernet Unmanaged Switch (GS110MX)?

You don’t need a separate volume for drive just a different shared folder. What I would say is have a shared folder for any files you do not want synced to your computer as the bulk fast storage. With your XS+ you probably will not be slowed down much either way because of the beefy CPU compared to my 1819+

SpaceRex! I really need your input. I think I might have a major issue with #14. I have 1 volume on my NAS. I initially transferred 8TB of data (videos, projects that need quick access) at 100mb/s. This worked great. For the past day, I've been trying to make a backup of my computer (and soon to be 2 other computers) and there are 400,000 files to transfer. My transfer rate is kb/s (sometimes less than a single kb/s). I think it's because a few hundred thousand files are tiny kb-to-mb sound files for music production. Should I erase everything and start over with 2 volumes? My Synology Drive initial backup is unbearably slow.

@SpaceRexWill 2 жыл бұрын

So you don't need to create two volumes. instead you can have 2 shared folders, one with drive one without

@BretSnyderMusic 2 жыл бұрын

@@SpaceRexWill I think I might already have that. I have a shared folder called "Main Storage" (where my videos and projects go), and if I transfer files right now to it, they transfer at a solid 100mb/s. Then I followed your guide on using Synology Drive and that falls under my "home" folder, and Synology Drive is where my transfers are slow as molasses (1-30kb up/down). So I think I might already have what you recommend. 😭

I see desktop motherboards coming on the market with 1x 10gbit and 1x 2.5gbit. Could I then enable jumbo frames 9k on the 10gbit port and just leave the 2.5gbit port default? And another question what if everything is plugged into a switch and the 2.5gbit line also discovers the NAS will data go the wrong way? How to make sure to have the NAS in the LAN network but not go back over the 2.5gbit connection @ the desktop side.

@SpaceRexWill Жыл бұрын

So yes you should be able to do this (assuming the motherboard is not cheating out or doing anything weird). If you wanted to make sure that the traffic never went down the 2.5 gig network for the NAS you would want to put it on a different subnet. That way you can ensure that the NAS is only ever routed through the 10GbE port as its only on that network

The DS720+ works well but the bottlenecks of only reading from 1 disk ( using both Shr an Raid1) this means that the maximum read/write speed of about 180Mb, you could use SSD for much faster access. 1Gb ethernet is limited to about 120MB maximum speed, you could try a USB Ethernet adapter.

Mine was slow because of a few reasons: - uninstall some of the apps on the synology that I'm not using (I think they are called moments but idk for sure - I think they also call them apps) - turn off the indexing programs - started freeing up space (it was almost full) Those things brought it from a crippling 5mbps to about 50MB/s. That's INSANELY different speeds. I'm on the DS220j - my other Synology with 5 drives transfers faster than 600MB/s read speeds over a 10gbs connection. And fully saturates a 2.5gbps connection (200+MB/s) since my Mac doesn't support the 10gbps usb adapter I'd bought. Fast enough to archive data for sure.

I have a MBP M1 and iMac M1. In another video you show file sharing betw. 2 M1 macs via TB3. I need to have a 2TB backup capability and at least 4TB of 'cold storage' of archived work. I am looking at a Synology NAS (4 bay or greater) but it looks like 10GbE or TB3 is well over $1K. My wish is to access the same files from either MBP M1 or iMac M1 so I can run jobs on either. My network is slooow 1Gb or wifi and I work in a remote area of the house compared to where the router is. My question: Can I attach a DAS to the iMac and use file sharing from the MBP to access the DAS, i.e., make the DAS into a multi-user device and thereby skip the network requirements of the NAS?; 1Gb or wifi. Re your other videos, thanks for showing all these options with IP over TB3 with Macs! If I cannot 'use a DAS' in a multi-user mode (me on 2 M1 macs), then what Synology NAS would you recommend?

Have you seen performance issues after upgrading to DSM 7? I have DS1817+ 8G RAM 8x10TB drives. After upgrade it worked fine then started to slow down. Just getting a list of files was horribly slow. CPU load low, plenty of RAM, if I reboot the NAS, performance is restored every time. I can transfer 100MB/sec on large files all day. Using rsync I can compare large directories no problem. Then it will later a day or so at most, slow down where comparing two directories goes from seconds to many minutes.

Anyone seen very slow synology devices that could only read/write with 50-60MB/s max ? I cannot make a NVR1218 copy any faster than this (Samba, FTP, etc), even command prompt copy commands run slow. Can this really be that slow because CPU is not fast ? I tested with many disks including WD red SSD. It doesn't sound right.

Watched many of your videos - great content, thank you for providing all this information and help! Here is an interesting problem, maybe you have an idea: I got a DS1821+ with a DX517 unit. All drives are 20TB Exos. One volume of the total size in a Raid6 per unit. I narrowed down the problem to the DS level: if I copy large data files from the DS to the DX, I get ~90MB/s (80-100% utilization) on each disc (equivalent to a transfer rate of 270MB/s). I tested the sustained write speed of an individual disc before setting up the NAS, and it's around 250 MB/s. Copying data on the volume via 10 Gbe starts out at 1GB/s for a few seconds, and then drops of to 270MB/s sustained as well. Similar result copying data to the main DS, just 2x faster because more drives. Looks like there is a bottleneck with the HDDs, I am just puzzled as to what it could be (RAM is 32GB, CPU does not go over 10%, SSD cache disabled). Happy to pay the consultation fee if you're confident you have a fix...

@SpaceRexWill Жыл бұрын

The main problem with wifi is not even throughput. With a good Asus router I get 70-80MB easily ( small apartment ) but latency. SMB especially is terribly chatty so everything feels slow if you work in folders etc. The second thing for me is a good SSD cache for anything that is iOPs bound. User interface/Plex UI/Photos etc. became orders of magnitude faster after adding an SSD read cache.

@Mr.Jean-Paul 3 жыл бұрын

Both in this video as well as your video of installing SSD Cache, you recommend NOT to use a read/write cache, instead a read cache only. I would like to know if your maintain this recommendation for DSM 7 RC, where the write cache can also be used to cache metadata in a BTRFS, which apparently improves transfer speeds for often overwritten files like in Hyper Backup, Active Backup or Snapshots? I used a read/write cache for several years, but noticed that it is saturated (always on 100%) since the installation of DSM 7 Beta/RC. Due to your recommendation in both videos, I switched to a read only Raid 0 cache in order to check if the cache does saturate as quickly as in the first scenario. The cache is used in Volume 1 RAID 5 in a 1520+ with 4 HDDs. And thank you so much for your well explained videos.

@SpaceRexWill 3 жыл бұрын

So the reason that you see that now the catch is now saturated is they changed the way that cache works. Now by default all IO is sent to the cache (I explain it more in depth in the video on RC1 that I am posting in about 20 min lol) which means that you cache should very quickly get loaded. writing the metadata can be done a-sync therefor I still say it is better for most users to use a read only cache as you get twice the space as well as no risk of data loss. The metadata will be read from the cache as well which will speed up the overall tree, should there not be enough ram.

@Mr.Jean-Paul 3 жыл бұрын

@@SpaceRexWill Checking your video about RC1 then. I only noticed that the choice to cache metadata is not given when selecting read-only cache, but still it may be cached as you say. No worry about the RAM, I’ve got plenty of it. Pssst…not saying how much, don‘t want my warranty to expire 😉.

How does testing drive perf on a _network_ shared fs give anyone any sense of the baseline performance of the synology itself? To do what you claim should be the starting point (baseline nas perf), enable ssh, ssh into the thing, and get fio running. That removes the network component and yields true best-case hw perf #s. For network, install docker and get an iperf3 container running. Get iperf3 installed on whatever device that's not so anemic that it can't saturate its NIC hardware. Then run that against the synology. Both as sender and as receiver. Tune e2e network as appropriate; mtu being most convenient/easiest. If you can't be bothered with the iperf stuff at least initially, at least enable the dhcp server on the synology (use different network block from existing), locate the synology close to a machine from which this smb disk testing should occur, and direct connect the two; no switches/routers in between. That should at least eliminate most net issues. it's still crap as a "baseline synology hardware perf" test though.

@SpaceRexWill 3 жыл бұрын

For ultra advanced users yeah it’s great to do all of this testing. But for your average user it’s wayyy overkill and going to be too hard to setup. That’s why I focus on what makes a NAS feel slow or fast, and for 90% of users, that is how quickly large files are transferred over the network. To the average end user it doesn’t matter if fio says it can perform 25kiops and sequential reads at 5 GB/s if they are over a 1 gig connection

My Synology is in the UK - download there is 80 meg, upload 20 meg. Here in Spain my download is 20 meg, uploads just 3 meg (I can make that 20/20 by switching to mobile) - what then is the most likely holdup - the broadband or the 2 mechanical 7200rpm drives on the Synology (raid). I could replace them with SSDs as I have here in Spain - but if the broadband is the bottleneck, no point. For reference I have some half-decent (but not 4K) movies on the Synoplogy and I can remotely watch them here in Spain without noticeable delays on our 4K TV.
