Drop in transfer speeds? Pro 4 ReadyNAS

Hi,
When transferring files from pc to NAS, the transfer speed drops to almost nothing. Then resumes a few seconds later but nowhere near it start of speed.
PC->Netgear Switch GS208->ReadyNAS Pro 4.
All network cables have been checked and they are all Cat 6. I’m at a loss. From PC to NAS unit must only be 2meters...
Any ideas?
Can the Ram be upgraded? (Currently 1gb)
Someone suggested upgrading to OS 6? (But I don’t think mine supports it, but as I don’t have support anyhow, worth doing? Is it possible?)
Thanks guys

    Hi Bobski2000, is your nas behind a ups (uninterruptable power supply)? If not, hooking it up to one to my knowledge gets the OS to enable the write cache. This could improve the preformance of transferring files to the nas significantly.

    Good luck with fixing and kind regards

      Wow, UPS? Never would have thought that would help. I’ll buy one as I need one anyhow, but will it work, I’m not so sure but it’s worth a try.
      Thank you

      No.  In OS 4 systems, you explicitly enable the write cache on the system->performance page on the web ui.  You can also disable full data journaling on that page.

       

      But I do recommend a UPS.

       

      On the main problem:  these settings can increase performance, but if they weren't touched then they don't explain a sudden drop in performance.

       

      I suggest downloading the log zip file, and looking at the network statistics (which are in network_settings.log).  Also look at the SMART information for the disks (either from the web ui, or from the log zip).

       

      • What firmware are you running?
      • What services and add-ons are you using?
      • Are you using both NICs in the pro?  If so, what aggregation setting are you using.

        Been and checked both settings and both are set as they should be.

        firmware is 4.2.31.

        using only the first LAN port.

        only have streaming on using one media folder. Nothing else, no add-one at all.

        SMART is okay on all drives.

        Ordered my UPS, should be here next week 👌🏻
