Hello,I have a ReadyNAS NV+ running sparc 4.1.13.It's connected with cat 6 cables to an ASUS AC66U gigabit router.My NIC is also gigabit compatible.I have quite slow read speeds for drag and drop.I get about 9-10mb/s read and 20mb/s write.I tried connecting directly to the NAS and I get the same performance.- Full data journaling disabled- Journaling disabled- Fast CIFS writes- Jumbo Frames off4 Hard drives1: WDC WD20EARS-60MVWB0 [1862 GB]2: WDC WD20EARS-60MVWB0 [1862 GB]3: WDC WD20EARS-60MVWB0 [1862 GB]4: WDC WD20EARS-00J99B0 [1862 GB]Any one has any ideas?Thanks

Are you testing with large files ( > 250 MB) or small ones?Can you try Nastester and see what it reports? http://www.808.dk/?code-csharp-nas-performance

Hi Stephen,I was moving large files.The results of the tester are consistent with my drag & drop results:NAS performance tester 1.7 http://www.808.dk/?nastesterRunning warmup...Running a 400MB file write on Z: 5 times...Iteration 1: 19.59 MB/secIteration 2: 17.71 MB/secIteration 3: 19.65 MB/secIteration 4: 19.66 MB/secIteration 5: 17.71 MB/sec-----------------------------Average (W): 18.86 MB/sec-----------------------------Running a 400MB file read on Z: 5 times...Iteration 1: 11.22 MB/secIteration 2: 11.22 MB/secIteration 3: 11.71 MB/secIteration 4: 11.96 MB/secIteration 5: 11.99 MB/sec-----------------------------Average (R): 11.62 MB/sec-----------------------------

Have you checked the SMART stats on the disks?Also, it might be good to check for 4K alignment (and if the NAS is very old, the block size). There's info here on how to do that: http://www.rnasguide.com/2011/06/22/why ... -readynas/

Not sure what I should be looking for in the SMART stats but they're not showing any errors.HDDs are 4K alligned and block size is 16k.

Any errors showing up in the NAS ethernet stats? Maybe copy them before and after a test.

I just tried connecting the NAS to the PC direct via a different cable and got the same results.
Also, I have already tried a different cable to the router prior to that.

Do you have a different PC you can test with?

Tested with a Gigabit laptop, same result.

Lesson learned, buy Synology.

Your speeds sound reasonable for the NV+ though I would have expected higher read speeds than write speeds. Your NAS unit is basically a model that was released back in February 2006. It was discontinued back in late 2011.

What version of Windows are you running?

All our current ReadyNAS models are much faster than the NV+.

My speeds are not reasonable since the performance guide indicates I should be reading at 33mb/s, not 10.

I'm running Windows 7 Ultimate 64bit.

The difference could be because of the green drives you are using. Green drives are lower performance drives.

In the performance guide, they are using 7200 rpm drives.

Not really. 33 MB/s is for the "optimal" configuration. Your settings are closer to the default, which is mid 20's.

[quote="fbmachines"]The difference could be because of the green drives you are using. Green drives are lower performance drives./quote]I also use the same drives, and I am getting around 17-18 MB/s read speeds with my stock NV+. And that system doesn't have 4K alignment.

So I think the slow read speeds are still unexplained, but I am thinking 18-20 MB/s is the ceiling.
