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, upgraded the storage twice with XRAID, run it on 1 1GB switch and replaced the fan with a slightly quieter version when I had to move it to my office instead of the basement.
The problem I am having is it is getting a little long in the tooth such that read/write performance is VERY LOW in comparison to new systems. Some of this could be the CIFS/Samba with Windows 10/8.1, but some of it is age. When transferring large files, speed drops down to an abysmal 1-2MBps, smaller files are better but only go into the 5-6MBps range. And when I try to stream video over SMB to my Boxee Box (running Kodi) it can studder. I had just tried to transfer 100GB and it said it would take 24 hours!, where a USB 2.0 thumb drive attached to the computer took about an hour. A long time ago (In a galaxy far far away :) for the Jedi Council ), this used to be the reverse. Transfers to the NAS were exponentially faster than USB.
So... While it works fine, it is probably time to upgrade. I originally bought the NV+ 4 bay since it was the powerful prosumer model and did some high-load stuff, running a lab of about 12 systems at home. Now, I have converted most of that all over to 1 large VMWare system, besides the Sun BLADE 2500 Solaris 10 workstation :) and while the NV+ introduced iSCSI, I never used it, but if performance shows, it probably would not work very well.
The models have diverged a bit, so not sure where to look now. What I am looking for is a good 4 bay prosumer model, similar to the NV+ of this time, that I can do the standard Samba, NFS and even iSCSI with good performance (Bonding network links perhaps), something that won't make media stutter when I stream it, and something that could possibly transcode it as well although It doesn't have to be Plex as I usually connect internally to my network via OpenVPN. The final part is the price. Since my NV+ is working, I don't want to spend an arm and a leg for a new unit, I have the WAF (Wife Acceptance Factor) to think about (answering the why do you need a new one when the old one works... :) ).
Thank you for your time.
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:

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.

Sorry to bring this back up, but has anyone used Plex Server on the 214 or 314 NAS boxes? I was reading about it and it seems transcoding is locked to 480p on the 214. Most of my media is 720p or 1080p and would like to steam it to my Laptop and Fire TV Stick at full 720p or 1080p. Thanks.
