ReadyNas NV+ (v1) Upgrade Suggestions
Hello, I am a long time ReadyNAS NV and NV+ User, I upgraded to the NV+ SPARC after my NV died well before NETGEAR was involved, and have been happy with it since, I have upgraded the memory to 1GB,...
Your NV+ should be getting around 20 megabytes per second on large file transfer, not 1-2 megabits. Have you checked the disk health?
Any new NAS (including the entry-level RN104) will outperform your NV+.
If you are interested in transcoding with plex, get the RN214. If not, then perhaps the RN314 - it doesn't do real-time 1080p transcoding, but it does have lifetime chat support. Technical support (phone/CHAT) by the way is for brand new products purchased from authorized resellers.
You can of course repurpose the NV+ for backup.
I will have to look into both of those further. AS for my current NV+,
On my Windows 10 and 8.1 machines, I was getting average 4.5 MB/s. On my Windows 7 PE test machine when I was migrating data off, I was getting about 2 MB/s.
I have 3 Seagate ST31000528AS 1TB Drives, and 1 Seagate ST1000DM003-1CH162 1TB Drive in a redundant X-RAID (3 TB Total, 1 Spare).
The SMART status' are OK. I have the following features enabled:
- Disable Full Data Journaling
- Optimize for OS X - My Wife has one Mac OSX pc, the rest are Windows.
- Enable Fast USB Disk Writes
I didn't enable fast CIFS writes though.
Also what might help, is when I run top via SSH without a copy, it looks like:
top - 11:24:03 up 100 days, 10:26, 1 user, load average: 0.23, 0.15, 0.18

When copying a file the CPU ramps up and smbd consumes MOST of it.

Thanks for the help and recommendations.
It's been a while since I tested the NV+ speed, so I tried it with NasTester ( http://www.808.dk/?code-csharp-nas-performance )
On my Win-10 system it reports 16.65 MB/sec write and 26.0 MB/sec read speeds on 400 MB file transfers.
The Win-10 system is using an SSD hard drive. Disable journaling, optimize for OS x, Enable fast CIFS writes are all set on the NAS. Firmware version is 4.1.15-T3.
I Turned off Journaling and enabled CIFS writes and ran the NAS Test for the 400MB file, but for 1 itteration since it takes so long, it stil reports about the same for write speed. Read speeds are higher, but lower than what you are recording:
Running warmup...
Running a 400MB file write on S: once...
-----------------------------
Average (W): 4.96 MB/sec
-----------------------------
Running a 400MB file read on S: once...
-----------------------------
Average (R): 19.24 MB/sec
-----------------------------Although I am only running 4.1.14. I have been waiting for 4.1.15 to be pushed to final before upgrading to it. Was hesitant on upgrading to a test firmware (T3), but if it makes that much of a performance different, I may have to.
I don't think the speed difference is related to the beta firmware - all it has is a couple of security patches over 4.1.14.
You might want to do a backup and a factory reset - then rebuild the NAS and reload the data.
Sorry for the delayed reply, I had upgraded to 4.1.15-T3 without any changes; however, I got an idea.
I mounted the nas again on my machine using the Windows NFS Client and saw some slight improvement on write and DRASTIC improvement on read:
-----------------------------
Average (W): 6.01 MB/sec
-----------------------------
Running a 400MB file read on T: once...
-----------------------------
Average (R): 51.83 MB/sec
-----------------------------Since I can use NFS, for now I will do this. I don't want to reset my NAS as I have a small percentage of stuff that isn't backed up. My NAS is 3TB, my backup drive for it is 2TB... so some of my media collection was excluded.
I will have to look at a new box to replace this and relegate this one as the backup.
Thanks again for all your help.
