Low 10Gb/s speed TS-431X3 (204MB/s)

[Rubberswe]

Recently bought the NAS and the SFP+ module, but cant get the transfer speed anywhere near 10Gb/s

Using static ip 192.168.0.112 on nic and 192.168.0.111 on nas
nic2:TP-link TX401
MTU 9000 on both nas and nic2 (tried different values 2)
My computer(nic2) is connected directly to the nas with a 2m cat6a cable via a 6COMGIGA SFP+ rj45 module

(nic 1 is used for internet with dhcp - puplic ip)

10gbps transfer speed to nas is:204MB/s (Nas adapter 1)
2.5gbps transfer speed to nas is 192MB/s (Nas adapter 2)

4 disks used: Toshiba 18TB 7200rpm in JBOD mode
Both qnap and win10 is reporting 10Gb linkspeed

What im missing?

I would say you need to change your disk configuration to RAID before trying to get near 10GB speeds. I'm pretty sure I read (somewhere???) that JBOD config slows down disk throughput and RAID is much faster.

Spanning jbod fills the disks sequentially. so maximum you get is the speed of a single disk..no RAID advantage

That explains the speed

Arghh, i was thinking about converting the disks to Raid0, but was unsure about the files on the nas, will they get deleted?
Moving them back to comp will take ages




/thank you

[dolbyman]

yes, converting spanning JBOD to RAID0 will destroy all data on the pool/volume

[Rubberswe]

After converting to raid0:
The testfile transferspeed is now about 500MB/s - but that file is 750GB.
All the smaller files(1MB-1GB) is still about 150-200MB/s (cant remember the exact speed, but it didnt increase much after converting to Raid0)

If i increase the internal memory to 8GB and install an m.2 2TB disk as cache will that improve the transferspeed ?

/thanx

[dolbyman]

no.. sequential operations do not profit from cache

if you want faster speeds, increase your bays (new nas) or switch to solid state

Crap, that **, but tx 4 the help
