ReadyNas NV+ V2 4 bay questions
Hello :D
I am looking to purchase either the ReadyNas NV+ V2 4 bay or the Synology Ds413(j) in the next few days, but I would appreciate some clarification before I make a final decision.
I have been down the route of DIY Nas's and haven't successfully managed to build anything that consumes so little power compared to ready built Nas's and apart from the HP Proliant Microserver, putting a nas together works out more expensive than buying a ready made one.
I have read a few reviews, from PCPro, StorageReviews and Andtech
http://www.pcpro.co.uk/reviews/storage-appliances/372292/netgear-readynas-nv-v2/2
http://www.storagereview.com/netgear_readynas_nv_v2_review
http://www.anandtech.com/show/5071/netgears-marvell-based-readynas-nv-v2-review
These seem to be a mixed bag really and there is nothing to compare directly with the DS413(j) as yet that I have found.
I will be using this primarily for serving my Samsung TV via DLNA, backing up a couple of windows computers and for file storage, performance is important, but I am not expecting anything earth shattering as both these are entry level NAS's.
The plus sides for NV+ V2 is the fact it has USB 3 ports, an LCD display easy accessible drive bays, X-Raid(2) and it's currently almost half the price of the Ds413j :shock:
The not so plus sides are that from what I have seen there seem to be very little in the way of addons for the NV+ V2 in particular ISCSI, not a deal breaker but it has been almost a year and this still doesn't seem to have materialised.
Power usage is possibly another issue, ReadyNas NV+ V2 seems to use about 20w more power than the DS413j, I know its not a massive difference and will take 50 hours to equate to a KW of power, but since the two NAS's use the same processor and the NV+ V2 uses half the ram and DDR2 this is surprising, I can only assume this is down to an inefficient power supply?
Is it relatively simple to upgrade the power supply? I ask this because at the moment the NV+ V2 is just under half the price of the DS413j so an extra £40 for a decent power supply would still leave me in pocket so to speak.
I have read somewhere that it is not possible to backup the ReadyNas to storage attached to the USB 3 ports? is this correct? if so I am struggling to see any point in having the USB 3 ports
I have also discovered ram not upgradeable, not a deal breaker, but wonder if this is a reason why so few addons seem to be available for the NV+ and Duo, I would personally have happily paid an extra £20 for this box and have it with 1GB or DDR3, ram is so cheap at the moment, I really fail to see how this was a big cost saving for Netgear, but as I stated earler not a deal breaker if it performs reasonably well then that is fine by me, I have about 3TB of files to transfer to the Nas once I have purcahsed and don't want to spend weeks transfering them via USB 3 :lol:
I have three WD20EARX oem drives that I want to put in the Nas, probably configured using Xraid-2 or hybrid raid if I opt for Synology.
Synology claim that using their HDD hibernation their unit will only consume <5.8W taking 40-50 seconds to wake the disks from smart tv, this would be acceptable for me as I will be using the Nas Ad-Hoc times when it is on and would want it to use as little power as possible when it is on, but will also make use of the shutdown/restart schedule for the times when it won't be used. Does the ReadyNas have any other power saving options to offer something similar to HDD hibernation and get anywhere close to 5.8W? What about something similar to Deep Hibernation consuming < 3w but quick wakeup and boot time < 3W wasted energy I know, but if boot takes a long time this maybe a reasonable compromise.
Also, can anybody confirm if the CyberPower DX600e UPS will work with the NV+ V2? I would probably have the NV+ V2 next to it and run the USB cable to the USB 2 port on the front.
If you have reached this far, thanks for taking the time to read this post and hopefully clarify some of my questions.
Cheers :D

- It seems unlikely that the power difference is due to the supply. I am thinking that the hard drives used for the measurement are part of the difference.
Synology says "Measured with 4 Western Digital® 3TB WD30EZRS hard drives. The figures could vary on different environments." http://www.use-ip.co.uk/datasheets/1327 ... erver_.pdf
According to http://www.tomshardware.com/reviews/3tb ... 82-11.html, each EZRS uses 5.5 watts when running a max throughput, so 22 watts would be from the disk drives.
If hitachi 7K3000 deskstar drives had been used instead, then each disk would use 9.2 watts, an increase of about 15 watts. - Thanks for the reply, do you know which HDD's Netgear use for their figures of: -
Power Consumption
52W typical with 4 x 2TB disks
48W idle, 22W with disk spin-down
If they are using drives similat to the 7k3000 thats would put the two pretty much on par for power consumption - The NV+ v2 also uses a brick power supply similar to that used by the 2 bay ReadyNAS units. The original NV+ (v1 with silver chassis) used an custom internal power suppy (as do the Ultra/Pro 4 bay units).
If you have the opportunity to actually put you hands on a ReadyNAS at a retail store, you will immediately note the quality and robust construction. I am currently configuring my fourth ReadyNAS over the last 5+ years. After I purchased my first, I never looked at any of the other units. I did extensive study and research before buying my NV+ in 2007 and there was nothing close. One thing I did was download the manuals from the websites and note any potential areas I was not happy with. At the time many required a special application on the client PC in order to access the host NAS. (The ReadyNAS uses RAIDar only to find any ReadyNAS unit on the network and activate the setup program [Frontview] but not to access the data files. You can also directly access Frontview to set up the unit directly from within a browser if you know the IP). Having had a NAS with the LCD panel, I would certainly hate to have to do without one. Those units without the front panel signal the alerts and messages in a different manner. RAIDar gives you a lot of information that can help for the 2 bay ReadyNAS units that do not have the front panel, but without the panel and without RAIDar you are reduced to decoding light patterns and flashes. - Hi and thanks for all the replies.
I would still like to know about current and future development for the arm family of readynas's.
I haven't found much in the way of addons yet, what is the reason for this?
I don't want to invest in a piece of stepping stone technology that will be superseeded in a few months by a v3 with more ram and cpu grunt. - Most Add-ons are done by third parties. You need to remember that the x-86 system has been out for five years while the ARM system has been out for less than one year. It is unlikely that the ARM community will have as many add-ons as it is considered an entry level system rather than the high end Pro line for which most add-ons have been developed. (Mid range x-86 units benefit from those add ons because the vast majority of them run on all x-86 boxes, including the discontinued 32bit NVX units).
The third parties developing these add-ons are users of units employing the architecture. A member (super-poussin) recently posted in another thread that he has 15 add-ons he is testing for the ARM based units. He developed a lot of the third party add-ons for the x-86 units. Development and enhancements of the ARM based system will continue by Netgear. This can be seen by the recent release of ReadyDrop for the ARM based units which has yet to be released for the x-86 units. The ARM based units also got the new Frontview interface (version 5) before the x-86 units which have yet to get it. - Hey BlokeUK,
I agree with you that no add-ons for ARM platform have materialized and has been a major complaint of mine (in additional to the RAM not being upgradable). Check out my recent post: viewtopic.php?f=10&t=66958
"I will be using this primarily for serving my Samsung TV via DLNA, backing up a couple of windows computers and for file storage, performance is important, but I am not expecting anything earth shattering as both these are entry level NAS's."
Reading above, if your going to use the NAS for just that, you should look into ReadyNAS Duo v2. I had the Samsung E8000 plasma streaming via DLNA from the NAS and worked quiet well. Just make sure you get a good wireless router or use the LAN on the TV. The Samsung's builtin media player is pretty amazing as it will play almost any format and works very well with the ReadyNAS Duo v2. The Samsung's wifi card broke on mine after 3 months of usage and still didn't work after Samsung's tech came to repair so I returned it to Amazon and purchased a Panasonic ST50, BUT unfortunately Panasonic was being cheap and didn't want to pay licensing fees for DTS audio so streaming from the ReadyNAS was not a good option (lot of MKVs have DTS audio). I ended up supplementing the Panasonic with a WD TV Live... woah sorry for the long side track.
If you read my post, I'm thinking of leaving the ReadyNAS community after 4+ years of use because add-ons for the ARM platform is basically nonexistent. Even after almost 1 year since the NV+ v2 and Duo v2 released, not much has materialized. Also, I was so blinded by my love for ReadyNAS that I didn't look to other NAS platforms (I mean firmware/software to manage the NAS). I've recently seen Synology's DSM software and it's looks super amazing.
Sorry to say, but after 4+ years of ReadyNAS Duo I can't wholeheartedly recommend ReadyNAS (the performance on the Duo is very good, but they also got rid of Jumbo Frames from Duo v1). - There are plenty of apps in development for Genie Apps for the Duo/NV+ v2 and there are some community add-ons available.
The RAM is soldered on to the Duo/NV+ v2 so we'll just have to live with the RAM not being upgradeable.
As for Jumbo Frames not being available one needs to note that the Duo v2 has very different hardware to the Duo (v1) and has a different OS. It's a new product not a second revision of the Duo (v1) though externally it looks somewhat similar to the v1 (there are obvious differences mentioned on my website). - Jumbo Frames is probably more the new RAIDiator v5 GUI not having the option, than the hardware not supporting it. Many options that were in v1 are not in v2, such as Printer support, Network UPS (later added?), DHCP server (yes, rare option).
Seeing as Sparc hardware from 2004 did it, I'd be surprised that this ARM setup built by NTGR in 2011 would not. Has anyone tried using ifconfig on shell to change the MTU?

Thanks this is reassuring, do netgear offer a free sdk for their arm nas?
The os looks like linux, so might even look at porting some stuff myself if I can find the time.
I'm still a little hesitant because of amount of ram and the fact they soldered it making it difficult to upgrade, and I'm still getting my head around this decision, it can't be down to cost alone, ram is cheap,
could it be thats its not upgradeable because netgear don't support memory upgrades?
Whatever the reasons I'm starting to lean toward the nv +
Appreciate all your detailed responses too :)BlokeUK wrote:

It should be possible as it is with my Duo v2 which is pretty much the same hardware as the NV+ v2 except the Duo v2 is only a 2 bay unit, i am sure someone with a NV+ v2 can confirm this for you.
