Streaming problems
Made a post about this a while ago but it was a bit of a mess as it was written while also investigating the issue. The problem I have is basically an inconsistent very low performance by the ReadyNAS system, which shows up mainly in streaming.
If I reboot the system, it will stream fine, indexing in explorer etc will respond quickly, file transfers are very fast (35-43 or so MB/s), you can copy files while watching a movie etc all spot on.
After a while of being left on, but no real specific timeframe, but generally less than a day (surely part of how a NAS generally works, very long uptimes!) this deteriorates and streaming will stutter even on low quality video files and sometimes music files, file transfers will slow down (8-10MB/s maybe), even opening a word or excel file it will sit at "Loading (0%)" for a few seconds, I've never even seen that message before now!! Also trying to browse the NAS, or copy a couple of files to different locations etc while streaming will be impossible, and result in the file playback stopping dead or badly skipping until a good minute after it completes.
Another bizarre feature is that with media player classic open, and playing a file (or even a file in paused, or stopped after playing) the file transfer rate and 'local' performance of the NAS will be very very low, as in lower than USB1, <1MB/s transfer speeds!
It's a ReadyNAS Duo V2, with a single Seagate ST3000DM (I think, that's from memory!) 3TB barracuda drive. I have wondered if the optimisation is just, understandably very poor for a single drive. It was bought with the intention of adding more drives as cash became available to add redundancy and then increase capacity... just like the ads!

- What firmware are you running? Also, what add-ons (if any) do you have installed?
- RAIDiator 5.3.7 and no add ons besides ReadyNAS photos, which comes pre installed, it's not being used though.
- So you are not using Readynas Remote? Just normal SMB/CIFS access on your local LAN?
- Edit: Looked it up and see what you mean now!
No it's connected via gigabit switch to the NAS, which also has the incoming internet, PC is on the VIP port. That's all that's connected to it. Just using CIFS/SMB, shares set as network drives. - It shouldn't be slowing down then.
Have you checked the disk SMART stats? Also, some of the newer seagates have issues, so you might want to post the model number (and the firmware version the drive is running). - I did check the firmware as I know of "clicking" issues with the seagate drives, it's on the most up to date possible already.

Load cycle count seems high? but I've no idea if it's just high, or that's high even for a load cycle count.
