Netgear's Marvell Based ReadyNAS NV+ v2 Reviewby Ganesh T S on November 9, 2011 8:30 AM EST

Netgear's ReadyNAS lineup is very well respected in the industry. This lineup owes its existence to the acquisition of Infrant in 2007. After acquiring Infrant, Netgear moved away from the custom RAID controllers (based on the LEON SPARC core [PDF]) in favour of Intel x86 based solutions. However, Intel based solutions are too costly for the mid-range SMB market. We have already seen vendors like Synology and LG using Marvell based controllers in their systems. Netgear is also moving to a Marvell based solution for this market with the products introduced today.
The 2-bay Duo v2 is meant to replace the existing ReadyNAS Duo and the 4-bay NV+ v2 is meant to replace the existing ReadyNAS NV+. Compared to the Ultra and Ultra Plus series, these solutions are much cheaper. They also sacrifice some features such as NFS and iSCSI. These are not used by a majority of the consumers in the economical prosumers segment. Hardware wise, both the products carry only one GbE port (compared to the two ports in the Ultra lineup). The table below presents the various home NAS models from Netgear.
Netgear's suggested pricing for today's introductions is presented below:
Netgear doesn't offer any specifics on the platform except for indicating 'Marvell Smart' in the packaging and a 1.6 GHz CPU at the core. Both the Duo v2 and NV+ v2 run on the same CPU, with the number of bays being the only difference. A look at the pricing table above reveals that the units compete in the same class as that of the LG N2A2 NAS that we reviewed a couple of months ago. Is the platform same? How does the performance stack up? We will see the answers to these questions in the next few sections.

ganeshts - Thursday, November 10, 2011 - linkThese are not vendor supplied numbers I am talking about.
A 6281 based NAS was reviewed here: www.anandtech.com/show/4510/lg-n2a2-nas-review
Look at the NASPT benchmarks and compare with what we got for the NV+ v2. There is a big difference in the robocopy benchmarks (46 and 21 MBps vs 77 and 35 MBps). For the general consumer, who doesn't care about speeds, the LG unit is a better choice at a lower price.
The DS212 specs seem to indicate that a 6282 is at the heart and it also has USB 3.0. I am yet to benchmark that unit, but I expect it to come in around what the NV +v2 achieved in the 2 bay configuration.
nasuser - Thursday, November 10, 2011 - linkYou can't use an LG benchmark to then make conclusions about a non-LG device! Just having a similar processor doesn't automatically mean the same performance. Maybe the next time you want to buy a car you'll go test a couple of Volkswagen - then you'll know which Audi to buy as they use the same engines
If you don't have your own benchmarks then you have no choice but to trust those provided by the supplier - in this case Synology - which shows the very little difference between their $200 unit and the Netgear $200 unit
But your article makes a major conclusion that the Netgear unit is effectively half the price of its' competition for the same performance, neglects all other aspects of comparison, and so states it is the best value for money. And that conclusion is based purely on extrapolating from a test of an LG device?
ganeshts - Thursday, November 10, 2011 - linkI don't trust manufacturer benchmarks because the test cases are not going to be the same across manufacturers. I always draw conclusions from the benchmarks that I have run myself. We have the following:
1. LG with 6281
2. DS211+ with 6282
3. NTGR NV+ v2 2 x 1TB with 6282
(2) and (3) have similar performance, and (3) is half the price of (2).
There is a new contender,
4. DS212 with 6282 and costing 1.5x the Duo v2.
I am making an educated guess that (4) will have performance similar to (3). I can't imagine how the engine analogy applies to the above description.
I will approach Synology for a DS212 review unit.
Daniel Egger - Wednesday, November 9, 2011 - link"By sacrificing some features such as NFS and iSCSI and cutting back on the DRAM, Netgear has managed to deliver the members at half the price of the competition's offerings."
So why is it in your opinion that castrating an already available feature would reduce the cost of such a product? The real reason for that is to lure non-experts into buying a more expensive version ...
However none of the brands deliver something I would consider to be a killer feature: All of the NASes allow for repartitioning while destroying existing data; what I would like to see instead is some utilisation of LVM to partition space on the fly and maybe even allow snapshotting and snapshotted backups.
All the smaller NAS products currently on the market are in fact toys without something along these lines.
nurgle - Wednesday, November 9, 2011 - linkAt the $400-$600 range, Wouldn't it just make a lot more sense to just use a computer? Even at the $199 range it seems you could pick up some old atom pc and use that instead. Not to mention you could run all the applications you would want on it (FTP, SFTP, FTPS, SSH, webserver, dhcp, nfs, cifs/smb, dns, firewall, NNTP, NTP, and on and on. I mean all these NAS things are just a stripped down linux box in the first place. Why not just have a linux box?
I get the laziness thing. I also get the people are too dumb thing. But it seems like a lot of people who are neither lazy or dumb are compelled by these devices.
irev210 - Wednesday, November 9, 2011 - linkSize, power consumption, web GUI.
Obviously this is something you can build yourself, but here are a few things to consider (coming from an avid QNAP fan).
1) Build quality -
My qnap is built like a tank. Sanyo OSCON caps, high quality cokes/mosfets, high quality delta PSU, ADDA fan
2) Power consumption -
The PSU size is perfect for the size of the NAS, so you get the most efficient A/C to D/C conversion.
3) noise -
Obviously it is designed to be quiet
4) Software -
Their web-based software is nifty, easy to use, and takes seconds to configure
There are a TON more reasons, I suggest you take a quick look at some of the neat features at qnap.com
Nowadays, I am lazy. Convenience and total cost of ownership are much bigger priorities for me.
KennethAlmquist - Wednesday, November 9, 2011 - linkHaving just built a system, I would say:
1) Build quality: You can buy good quality components and still save money over a pre-built NAS. My build:
- Intel 620 2.6Ghz dual core Sandy Bridge processor ($69)
- Intel DB65AL motherboard ($85)
- 2 x 1 GB memory (had on hand, ~$20 otherwise)
- FSP AU-400 Aurum Gold 400W Power Supply ($76)
- NZXT Source 210 case ($40) + front fan ($8)
That's $100 less than the NV+ v2 without drives, including a brand name motherboard and a high end power supply.
2) Power consumption: The Aurum Gold has an efficiency of around 86% with a 40 watt load. I assume that the NAS manufactures get better value for their money by going with power supplies with lower wattage ratings. I don't see any reason to believe that they use more efficient power supplies. High efficiency at low power is expensive, so I'd hazard a guess that the NAS manufactures go for 80% efficiency.
Under load the system I built draws 49 watts, compared to 28 watts for the two drive Netgear unit, but that's with a much faster processor and 8 times a much memory. The NAS may have more energy efficient disks; I didn't get the Western Digital WD20EARS drives I wanted because of events in Thailand. An apples to apples comparison might give Netgear a 10 watt advantage. At that rate you are not going to get $100 worth of electricity savings in a reasonable amount of time.
3) Noise: The build I did is virtually inaudible. The only NAS I can compare it to is the Iomega StorCetner ix2, which is a lot noisier.
4) Software: If QNAP doesn't sell their software separately from their hardware, that suggests that they have looked at the market and concluded that their software doesn't provide a compelling advantage over the competition. Presumably the appeal is that they install and mostly configure the software for you, and it works well enough that you don't have to worry about it. And yes, I do understand the appeal of that. But if you have the time and inclination to deal with the hardware and software yourself, you can do better than a pre-built NAS.
T2k - Tuesday, January 17, 2012 - linkYou are clearly clueless about this market, I must say.
Build quality with $40 case and $8 fans? ROFLMAO!
Aside of these stupid claims most NAS boxes are not only about quarter of the size of your fugly build (NZXT, OMFG) but also noiseless, cost actually the same than your ugly build and come with 3-5 years of warranty, all included, no need to keep contacting 5-6 different el cheapo PC parts vendor when they die.
But your most hilarious point was the last one:
"If QNAP doesn't sell their software separately from their hardware, that suggests that they have looked at the market and concluded that their software doesn't provide a compelling advantage over the competition."
:D :D :D
Did it ever fuckin' occur to you that they chose to keep it proprietary because THAT IS the main differentiator for a NAS box? And that they maintain their own fork, you don't need to shit, only install single updates?
Boy, you are one hopelessly clueless bloke.
C_H_I_P - Wednesday, November 9, 2011 - linkIs it me, or is the SKU for version 1 and 2 the same ?
C_H_I_P - Thursday, November 10, 2011 - linkFigured it out for myself.
V2 == RND4000-200EUS
V1 == RND4000-100EUS
