The Read speeds sustain at 800 MB/s. r/synology I am transferring 450 Gig of data from my QNAP 219+ to my Desktop PC. no one else has come up with a solution for your slowness in the other thread you had raised with similar issues. And if I go to and from my m. 2 EVO I recently purchased a TS-212 and it appears to have slow read/write speeds. QNAP routers use next generation Wi-Fi 6 for high-speed wireless connectivity. I realise that the setup that I'm using wont give me full performance offered by the NAS, but I would have anticipated much higher speeds with the setup that I'm using. 2420 • APC Back-UPS ES 850G2 I am running into an issue where I see slow file read speeds from my QNAP, and I haven't been able to figure out what is going wrong. Filesystem performance: 390MB/s RAID I get "slow" write speeds, 290Mb/s , I'm surprised that you can achieve 800mb/s My read speeds is 1300 Mb/s When I connect via 10GBE network connection , I have 500Mb read and write Speeds. It has been running for 13 hours and has not yet completed 300 Gigs. Quote; Post by wiffola » Tue Jan 25, 2022 5:43 pm. Perform Sequential Read Testand replace the disk which has low disk speed (for But the read speeds from the NAS to the PC are at 300MB/s max. I CANNOT WAIT for QNAP to release the QSW-M1208-8C (I know, it's not big enough if you need a 12 port or 16 port 10G switch) - but it will be at least an alternative to Netgear at a reasonable price. This is well below the performance this I am transferring 450 Gig of data from my QNAP 219+ to my Desktop PC. The setup (for the test): It has not been even a month since my prized purchase and I have noticed painfully slow write speed (approx 130-150KB/sec) and read speed (ranging from 5-10Mb/sec) on eth0 for my TS-412. 4x 2TB Samsung F3 (HD203WI) RaidZ1 ZFS + 8gb ddr3 Crucial [^] QNAP TL-D400S 2x 4TB WD Red Nas First, 3 of your results (CIFS read and write, iSCSI read) ran at link speed.

Hello r/qnap Community, I have set up a new TVS-h1288X with 8x 6TB WD Red Pro and 2x 1TB Samsung 980 NVMe drives. when creating two virtual machines which intensively read and write data, you should create one LUN for each VM to distribute the load. Are there any possibilities that it's all wrong from the beginning that i set up the qnap? these slow ARM NAS that 'look' like powerful x86 equivalents have always been a source of grief, as the speeds disappoint I am trying to transfer files to and from a new TS-431KX and the performance seems unusually slow, in the order of 30MB/s. i have enabled write cache and the setting below, high performance mode. If you meet slow file transfer issue over the network, follow the steps below to diagnose the issue 1.

If you ever find a true smoking gun I’d love to read an update from you here. Write speeds to the NAS are 100-300 MB/s Double check that both QNAP & PC are set to Jumbo Frames (9k). I have created a RAID1 (2) SSD Storage Pool for storing data files that are used by an application running on my PC. This can significantly reduce performance especially if resync is set to the highest priority. Theoretical max is 12. If we network from one computer to another (from desktop to desktop) we get 500mb+ up and down. Please, participate and enjoy! Read speed cannot be that slow compared to writing. I think setting Jumbo frames to 9K causes this (in my LAN at least). VERY slow file transfer. If I set the NIC to 9000 the speed drops to 600-500 r/w The speed is okay, I would use it do editing with 1 -3 editors max. Share Sort by: Best. i. But in RAID 6 I would have expected the speeds reversed (faster read than write). QNAP routers. iso file to it, speed is around 20MB/sec Coping the same file from it, speed is around 30MB/sec QNAP TVS-473e 4x 4TB WD REDs - RAID5 - 2x 500GB M. with qnap and pc connected i have ~40mb/s write speed via windows 10 mount (samba).

Is there anyway to increase my write speed with TB3? Thanks for The following factors may slow down the speed. I've seen it go down as low as 10 MB/s. QNAP SSD Read/Write caching feature helps random IOPS performance by re-sorting (reducing write) block addresses in cache to reduce load on back-end disks. Cache size impact, larger the better (to create more Switch: QNAP QSW-M408-4C Desktop: Asus XG-C100C 10Gbe NIC Jumbo frames set to 9000 on NAS and switcher but not on NIC.

In QTS. RAID 6 with 6 drives is limited in write speed to the speed of a single drive. I have 4 6TB Toshiba drives in my QNAP, and they are setup as individual drives (not pooled, and no raid). The Read sustained at 785 MB/s. When i connect through the network (using the switch and the same cables etc) to my other computers i get ~930mb/s read speeds. How do I check if the NAS is slow? If you are experiencing the slowness in web UI, use Resource Monitor to determine which process caused the issue. Read speed can use multiple drives though, hence Slow write speed over 10gbe with Raid 5. My write speed is saturating the GbE speed at about 110-115 MB/s, but my read speed is always somewhere between 20-40 MB/s. I get 150-400 MB/s sequential read speed, whitch is way below my expectations (900 MB/s). I realize RAID 6 is slower, but both my Thecus and QNAP are running the same gigabit ethernet.

However, the speed fluctuates a lot, sometimes as low as 150MB/s. An encrypted shared folder/volume/external drive may slow down the speed, please run the speed test on a unencrypted shared folder/volume/external drive. Hello r/qnap Community, But the read speeds from the NAS to the PC are at 300MB/s max. End result was 56 MB/s. I don't know what your NAS is capable of, but I suspect you're only testing your data cache here. You may experience performance issues for the NAS, this may be due to some settings applied on the shared folders or volumes, such as encryption or QNAP focused community, to share news, tips and discussion about QNAP products and QTS/QuTS usage. Just today when i was about to copy data onto it the speed dropped down to measly 2mb/s and sometimes getting around 30mb/s Slow WRITE speed, could be one the following reason. When copying a 1.

I'm hoping that I'm not being unrealistic in wanting better speeds than what I'm currently getting. Click on Processes then Enable Group by Application. Removing the Ultra-High Speed Tier. I get 150-400 MB/s If you’re talking hundreds/thousands of small files and such, you are almost definitely hitting the random read/write speed limit of your drives, which is like 1-4MB/s. Reset the switch - speeds back to normal. Netgear GS108Tv2 switch, VirginMedia Fiddling with some settings will sometimes improve speeds a bit but never seemed to be a permanent fix.
