I just bought a ReadyNAS NV+ 2x750 and am trying to transfer all of my data from a raid array to it so I can retire my old server.First I tried to use EMC to get all the files over to the NAS, but that did not work at all with an average of 40,000 errors in compares ortimestamps per partition.I could not copy directly from the SATA raid through my network because the server always has files open on almost every partition.But I did try one partition of 10 gig with 8 gigs of files on it. It started well but eventually dropped to a speed of less than half ameg per sec and said it would take days so i aborted it.I transferred one partition directly to my new laptop HP Dv7t widescreen over the network very quickly. i then tried to copy that10 gig partition worth of files to the NAS through my gig network and it still was averaging maybe 500k/sec. This is with the laptopgig ethernet card set for jumbo as well as the NAS. I have done all the performance tweaks to the NAS from the forums. I run througha dlink DIR-655 extreme.Looking through the forums I decided to try a direct connect and transfer started at about 2mb/sec, climbed slowly to 8-9mb/sec,and then continually dropped over time to about 500-600k/sec and stayed there. Needless to say it took hours and hours to finish,and I have 22 more partitions to copy :( If I grab a big file and drop it to the NAS transfer is 28 meg/sec both ways. I realize there is a big difference between this and awhole partition full of files and folders of various sizes, but I really don't think it should take 9 hours to transfer 8 gigs over a giglan should it?Pretty disappointed now because I am looking at days and days just to get my data onto the NAS, and if file transfers are thisslow I might as well just use a usb external drive where I average 12-15 megs throughput.I have ordered a memory upgrade for the NAS and 2 more 750's, I sure hope there is some way to get better data transfer rates.Can anyone help? The laptop is running Vista Home Premium SP1 (of course). The NAS has been updated to latest softwareand firmware.It seems a lot of Vista problems with speed of transfer, but I have tried all the tips here and no matter what the rate alwayslevels at 500-600k/sec

Please try this solutions.faq.php#I%27m_getting_poor_performance_with_Windows_Vista._Is_there_anything_I_can_do%3FAlso if you are running any sort of security software or virus scan software please try turning it off, as I have seen such things as McAfee slow transfer speeds down considerably.

Thanks for the reply, but I have already done all of the tweaks suggested at this site. Nothing seems to really makemuch difference. Dang Vista has some serious problems, but if I downgrade to XP Pro my HP laptop support andwarranty go out the window.All I am trying to do is copy data from old drives to the NAS and it has been days and still no reasonable solutionthat runs at decent speed.I can drag and drop large files back and forth at up to 28m/s .... but as soon as I try to copy large collectionsof folders and files of various types and sizes, the transfer rate starts high and quickly drops to around 500-600k/sec.What I have done now is format a USB as Ext3 using readdynas, copied files from my vista machine into that driveusing the driver for windows, and then I hooked the USB up to the NAS and am doing an nas backup to see if thatis any faster at all, but so far it is also crawling along for a 5.3 gig backup.One thing I did figure out with permissions was that Vista in all its power takes any drives or files created in anotheroperation system and makes them read only for safety. So if you want things to end up OK you have to takeownership of the drives in Vista (takes forever), and then make sure the shares on the NAS are set to assign permissions usingshare permissions.Update: the 5.3 gig backup direct from ext3 usb to NAS took 30 minutes! When compared to what Vista was going to take thisis at least one way for me to get my data onto the NAS, which is all I really need to do since normal use will not becopying gigbaytes of data back and forth.

Use FTP or rsync for faster transfer speeds - that is my tip..staffan

I was having the same slow down problem but now.....Try this:1) Go and get a Netgear Gigabit switch GS6082) Make sure you have the jumbo frame setting ON for the NV+3) Set your computer jumbo frame to 7936 (if you have a Mac, it's easy! I'm not sure about PC, sorry!)4) Connect your computer & the NV+ to the GS608 Giga switch while they are off5) Turn on the switch, NV+(it may need some time to boot up) & your computer6) DONE!My experience:Before: Read ~ 12 to 14 MB/s Write ~ 10 to 13 MB/sAfter: Read ~ 38 to 40 MB/s Write ~ 34 to 36 MB/sI reckon the problem is the router having jumbo frame issue even it said it's a gigabit router! (Believe me, I try so many from different brands!)I hope all these can help, good luck!

Even when I try direct connect bypassing the router (DIR 655) the speed does not improve at all.I strongly believe that it is just something I have to live with when using Vista. I have applied every tweak there is for improving file copy and directory listing performance with Vista and the best I get in I/O tests is 12-14 read or write.Now that I am done transferring entire drives to the NAS it is not really much of an issue, but I would really like to see the speeds that others are reporting.

No more ideas on how to solve this problem?

Have the exact same problem with speeds all over the place but most of the time in the really slow regions :(
Tried all of the tips above but no change.
I use Vista SP2

I have just bought the NV+ and I am really disappointed so far since I already experience slow speeds when just opening JPEG's stored on the NAS (using Vista HomePremium SP1, wireless connection). When I bought this ReadyNAS NV+ it said it should work with both Windows and Mac OS X (I mostly store all my files from the Mac, but I want access to pictures and movies etc from the PC or Playstation3).

I haven't had time to read all topics and forums about how to set up the ReadyNAS yet, but I mostly use Mac OS X and I plan to store all my files on the NAS (using both PC and Mac). These slow speeds, are they only a concern with Vista or will they still exist when using Mac OS X? For the Mac I use a network cable connection (no wireless).

Will there be a problem to store my Mac OS X created files to the ReadyNAS and will there be a conflict when Windows Vista is getting access to the same files and folders?

Thanks in advance.

I have windows 7 and the speed of uploading a 13GB file was going at the speed of 4.97MB/second. That is not acceptable. I ran the same file to a Thecus NAS and the transfer speed was over 20MB/second. Netgear has to fix this. This is even after the latest firmware (4.1.6) installed on the Netgear Readynas NV+.

Despite Jumbo Frames supposedly being faster, I had a lot of problems with my NV+ and spent days mucking around and testing and eventually found that I was much better off just turning the darn Jumbo Frames off. I don't think there is any industry standard for Jumbo Frames and I believe that incompatibilities exist between specific devices. Here's my results:

PC & NV+
Jumbo Frames ON for both PC and NAS: Write = 16.4 MB/s, Read = 22.2 MB/s
Jumbo Frames OFF for both PC and NAS: Write = 22.2 MB/s, Read = non-responsively slow (due to switch having Jumbo Frames enabled)
Jumbo Frame OFF NAS, ON PC: Write = 22.2 MB/s, Read = 33.3 MB/s

MAC & NV+
Jumbo Frames ON for both Mac and NAS: Write = non-responsively slow, Read = 27.0 MB/s
Jumbo Frames OFF for both Mac and NAS: Write = 19.2 MB/s, Read = 23.8 MB/s
Jumbo Frame OFF NAS, ON Mac: Write = 18.9 MB/s, Read = 33.3 MB/s

Conclusion from my testing is that you will always get faster performance on the NV+ with Jumbo Frames turned off than you will with it turned on. Since I have another NAS that works fine with Jumbo Frames turned on, I tried to find a balance where I could have the rest of my network on Jumbo Frames (PC's, Switches and my other NAS) but leave the NV+ with Jumbo Frames off. I think the NV+ actually gets better performance if Jumbo frames is totally off but this slows down everything else for me.

Try this

http://home.bott.ca/webserver/?p=226

Made a huge improvement for me. Browsing images was unusable beforehand.

Not sure if it will have an effect on a wired network, but it's gotta be worth a shot :wink:

Make sure you enable jumbo frames on your Mac's (or other client's) end. What used to take me an hour in write time now takes me 5-6 minutes.

Howdy y'all!

I'll try not to be a curmudgeon this time. ;-)

My NV+ is 256mb RAM, latest Raidiator/OSXRaidar, RAIDX 4x Seagate 1.5TB (firmware SD17, but Seagate claims these are NOT in the required firmware upgrade SN range)

I've hooked up a Seagate FreeAgent 1.5TB USB drive to the NV+ using one of the USB ports on the back. I formatted it with the NV+ to ext3 filesystem, thinking that the NV+ would like this better than FAT32 or HFS+.

I'm now copying over 1.5TB of stuff from the NV+ RAID to the 1.5TB FreeAgent using rsync via a terminal. i.e.:

rsync -a --progress /c/home/captain /USB_HDD_1

...so no data should be going through the network, other than the terminal text, which should be very non-intensive, right? Other access to the NV+ is non-existent during this test, though when I DO access it the rsync rate plummets.

According to rsync I'm only getting, at best, ~3MB/s instantaneous, 2.5MB/s average, transfer speeds, and that's on multi-gigabyte size files. On small files its in the x.xxKB/s area. Doesn't this seem very slow for a pure USB file transfer? Can anyone give me some suggestions, please? Could it still be the firmware on the Seagate drives? If so, is there some way to update the firmware, since Seagate doesn't want to let me in on the secret given my SNs?

hrmm. I just had an idea to shut OFF all services via frontview... That really shouldn't be necessary though, should it? And shouldn't USB rates on a non-hubbed USB direct-connect be closer to 40MB/s?

Ok, ALL services other than rsync and https (for frontview) are turned off, so nothing should be bogging this down. I'm still seeing rsync reporting only around 2.8MB/s.

FWIW, I also have, under System/Performace in Frontview, checked:
Disable full data journaling
Enable fast USB disk writes

Thanks for any ideas!

I just bought a NV+, put 4x 1.5 TB seagate hdds in raid 5, that's all fine and dandy. It's on a gig network. It's running the latest raidator 4.1.6. Like everyone else has been saying my network speeds are from 3mb/s to 11mb/s. I've tried different cables, a different router, different mtu speeds, went through the full/half duplex options for 100mb (weird we don't have options for full/half 1000mb) but while set at auto negotiation its 1000mb full duplex (the speeds seemed a little more consistant at 100mb half duplex). I also tried setting my ip to static and not. I should also note that i found with jumbo frames off i get much better speeds.

Should also note my speeds on the exact same workstation to another network storage can see 20mb/s to 40mb/s.

All of these observations are normal for Gigabit Ethernet.....

All of my computers are Windows XP SP3 or Fedora Core on 100 Mbps Full Duplex links; no wireless in my network (security reasons). All machines get a consistent 80 to 90 Mbps download (read) and 40 to 45 Mbps upload (write) to all 3 of my NV+ units. All 3 NV+ have 1GB of RAM.

So, I've swapped out all the Seagate drives (so the Seagate firmware bug is now eliminated as a possiblity) with these new Hitachis. Of course, I can't EXPAND the X-RAID, so I've been copying all 4TB-ish using rsync. The BEST speeds I've seen in the last WEEKish of copying have been around 1MB/s. This is TOTALLY UNACCEPTABLE!!

Something is just plain wrong here, and has been so since the get-go with my NV+. The network, and particularly the NV+, is quiescent aside from this rsync process. I can get significantly faster throughput from a Linux box which is routed through even more switches than the NV+ (but includes going through the ONE switch between the NV+ and the target Mac).

1.15MB/s from NV+ to Mac is the BEST I can get, and only on LARGE files (small files drop to a few KB/s and each file takes a long time!)
16.71MB/s I just got from Linux box to Mac with a 756MB file.

Note: just for grins I rsynced a bunch of small files from Linuxbox to Mac. The reported speeds are also low, but the speed they run through (i.e. file after file after file) is EXTREME compared to NV+ to Mac doing the same rsync copy. Just a guess, but I'd say I could copy my whole 4TB from Linuxbox to Mac in a day. I think it was about a WEEK ago I started the rsync from NV+ to Mac and it's still plodding along, but I need to reboot the Mac soon just for general Mac maintenance!! :-/
