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.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

- honcho - I guess the old adage of 'beggars cant be choosers' springs to mind!
Dropping $380 on a NAS when one was in the store looking at me for $200 is pretty hard - in the long run though I think the Synology may have been the better route.
I ended up buying 2Tb drives (WD20EARX) as the "approved" drives from the HCL were slim pickings and larger cap "approved" drives too expensive.
As of yet, I have not got them installed as after I put them in the NAS the LCC counts started rising v quickly - this is a known problem with WD drives and the synology suffers from it too...however I think the "approved" HCL list for Synology is larger which would have given me more choice to find the right drive within my budget.
If you are not in a hurry to buy, it may be worth waiting a little to see if Synology ever drop their price...you get what you pay for. - I still have not purchased a nas yet, still a few questions I need answers too before I take a plunge.
One other question i hvae after reading about USB 3 performance is what is USB 3 performance like on the NV+ V2.
I read that performance of USB 3 implemented using BOT doesn't offer a great improvement over USB 2 and need to implement UAS to maximise USB 3 potential.
Looking at the synology DS413j this is almost rwice the cost and does that extra 256mb ram really justify the cost other than the extra addons?
The DS413 more expensive again offers very good read/write performance but is 3 x the price so it seems you do get what you pay for.
So I have it down to USB 3 now being the deciding factor, otherwise may as well go for an ultra or pro or one of the synology DS 410/11 models that only have USB2, but also have e-Sata
I can not find any performance figures for USB 3 on the NV+ V2 or the DS413(j)
Anyone copied files to/from the USB 3 on the NV+ V2 and what sort of performance do you get over USB 2?
Thanks in advance - Well i do not have a NV+ v2 i have Duo v2 but its the same specification for the hardware,
Drag and drop between USB 3 Drive connected to NAS and my windows 7 machine
Read avg: 40-45 MB/s and write avg: 35-40 MB/s - toomanybarts - there has been an application called wdidle3 that will stop the LCC counts from climbing. It basically turns off the internal drive sleep function and lets the NAS control it. WD did much the same thing with their new Red Label series and they can't keep up with demand.

Thanks for your reply
Is that USB 3 - USB 3 or USB 3 over USB 2 Win 7?- That has to be USB 3 as those speeds are in excess of what USB2 will do. USB2 claims effective throughput of 35MB/s, but 20MB/s is more like it.

:shock: I thought USB 3 was 10 x faster than USB 2 :roll:
I would have thought 100 mb+ would have been more like the speeds allowing for the fact that 500MB is only a theoretical maximum and the theoreticals are rarely achieved.
That is not what I would expect for USB 3, I would be want x2 that at least I guess the NV+ V2 uses BOT and not UAS as those speeds are more in line with the older BOT implementation than the newer UAS
See this link for info http://www.tomshardware.com/reviews/usb-3-uas-turbo,3215.html
Thanks for info anyway PapaBear your replies have been most helpful so far, but I want my decision to be right, this is going to be a decision I am going to have to live with for at least the next 3-5 years- PapaBear - yeah I have a bootCD with WDIDLE3 on it - I need to borrow a friends PC as I was getting errors - it seems my SATA controller on the host PC is via PCi and not directly on the motherboard - or something like that, I cant remember the exact error, but its a known limitation of WDIDLE3!
One question I have is that you mention disabling the head parking allows the NAS to control it - I have not heard that mentioned before?
If so, then maybe when I do set WDIDLE I should disable it completely?
All other posts seem to suggest using the /s300 switch which would set the timer at 300seconds... - toomanybarts - I am not sure about disabling it, I do recall posts about changing the timing. The only WD drives I have in my NAS units are two of the new 1TB Red Labels which were designed to be used in raid boxes, which some one commented that the head parking feature was disabled. I would go with what the other posts said, for I have never personally used the function as I have not needed it.
- BlokeUK - the claim for the USB3 standard is up to 5 Gigabits per second, which happens to be 5x the speed of a Gigabit network. It is also far faster than the internal throughput of the NAS units, unless you have a rackmount x-86 based unit which is designed for up to 10 Gigabit per second networks. The theoretical limit for a Gigabit network connection is 112 Megabytes per second (1000/8 for the 8 bits per byte) although some of the older Pros, the new Ultra 6 Plus and the new Pro6 have recorded 120MB/s. It's also 67 percent faster than the SATA 3 theoretical max of 3000Mb/s.
Note also the operative words "up to" which covers a speed range of from 0 to 625MB/s (the theoretical max). Just for grins, since I have a USB3 Flashdrive (Patriot XT 32GB) and recently installed a USB3 add in card to my desktop (C2D E6750, so not the fastest). Copying from my Pro6 to my desktop a 2874MB file took 42 seconds for an average of 68MB/s. Copying that same file from my PC to the flash drive was inconsistent, the first time the copy seemed to stall so I killed it and the second time it took 184 seconds for an average of 16 MB/s. I then tried a test folder of a variety of file, 657 in all plus 25 folders for a total of 683 MB. The first try from the Flash to the PC took 13 seconds for an average of 53MB/s and the second time took only 7 seconds for an average of 98 MB/s. I then tried to copy the test folder from my PC back to the Flash and the first trial took 98 seconds for an average of 7 MB/s and the second time took 62 seconds for an average of 11MB/s.
The card on which the flash drive was packaged says "up to 90MB/s Read" but nothing about writing, which is always slower than reading. On the test with the 600+ files and the 25 folders it did seem to bog down in the write.
