    The only thing that I would add is that Netgear is really taking their ReadyNAS product line seriously with their support. I reviewed on of these units as well (mine came with 2x 1TB Toshiba drives included) and I had some very strange issues with the software (6.0.8). Without going into the details (ejecting external usb drives was one), I notified Netgear about the issue they had a firmware fix the next Monday (firmware was originally 6.0.8 - and was updated to 6.1.1). To me, that was a huge plus. Knowing that your support ticket,etc would be investigated and getting such a fast patch issued shows their commitment to this product line. Reply

    Ganesh,

    I'm wondering how likely is it, if you were to buy/use this in a home, to actually use the OS that comes with the system, rather than WHS 2011, or a Linux-based server OS (CentOS, etc)? Can you go a bit further with the software aspect of it?

    I would just use the OS that comes with it. There's other features of the OS (like Power Timer) that allow you to set a schedule for when the NAS is on - and it also has WOL functionality. Inside the OS is support for SMB, AFP, NFS, FTP, iTunes, ReadyDLNA, etc. Also in the OS is a free antivirus.

    There's also a one touch backup button that can be configured to whatever you want to backup (like just certain shared folders) or you can schedule automatic backups. There's nothing too special about the OS, but there's really nothing missing from it either.

    I agree with anactoraaron. This is an off-the-shelf NAS. If the software features don't fit, you are better off with a WHS server or custom Linux DIY build. Also, as far as I can see, the only complaint that can be put forward 'core-feature-wise' is the lack of LVM support -- i.e, say, you get the 4-bay variant and want to store some data with single disk resiliency and some with dual disk resiliency -- it is not possible with ReadyNAS OS 6.x.

    BTRFS includes "lvm" just as zfs does. In fact, that's one of its criticisms.
    Since btrfs supports redundancy using the chunks model (default 256MB), rather than at the disk level, you can have multiple redundancy options within a single disk (not a great idea for multiple reasons, but should be doable). Of course, you can span this over multiple disks to get the desired effect.
    Something like:
    mkfs.btrfs -m raid 1 -d /dev/sda -d raid 1 /dev/sdb /dev/sdc
    I should think.

    I did mention btrfs's LVM support in the article, but the problem is that Netgear's firmware doesn't implement it. Reply

    In the article you said it was supposed to be using the code that was employed in Oracle's deployments? Reply

    Yes, but not all features are exposed to the end-users. I guess the really adventurous users could try out certain things over SSH, but without official support, it is going to be pretty dangerous. Reply

    The feature I had in mind was proxy server for web caching, content filter, security (something like Squid). I realize this is kinda getting away from a "NAS", but with the specs listed, I don't see why it couldn't. Reply

    While Oracle may now include it, Redhat is still on the fence about it with the upcoming RHEL7, and still is working out stability before endorsing it for performance reasons. If you want a better filesystem, you can get an HP Microserver and pair it with zfs. I'll let others take this netgear experiment. Reply

    Final paragraph states the product name as the "ReadyNSA" am I the only one to find that interpretation hilarious? (sorry for being slightly off topic). Reply

    Thanks for noticing that. I fixed the typo now :) Reply

    Using btrf is certainly an interesting choice. It would be nice to see an article that explains the advantages of using it instead of ext4. Reply

    Ganesh, Thanks for the review - just wondering if you know if this unit supports Hyper-V virtual machines via SMB ? I have been trying to find out from Netgear for a couple of days but no one can answer me. Windows 2012 R2 Hyper-V allows the use of SMB 3 file shares to host virtual machine files. Can this unit work for me? thanks in advance Reply

    To be honest I haven't ever really considered a NAS for storage but if I were, a two bay NAS seems a bit useless to me. So you can do RAID 1 and lose half of your storage or do RAID 0 and gain your space but lose any hopes of recovery if one of your drives dies. Wouldn't a 3 bay NAS be the minimum common sense size? Reply

    You don't lose half your storage with Raid1. Unreliable storage has limited value. You keep all of your data if one drive fails, which is a lot better than what happens with a failure on any of those 1 disk NAS units out there. If you want capacity or higher performance, then you get a 4+ disk unit, or roll your own. Reply

    When I had a drive failure on the first drive of the RAID pair in my old ReadyNAS Duo, I learned that the second RAID drive was not accessible, since the ReadyNAS Duo boots from an operating system installed on the first drive. ReadyNAS RAIDar could not even see the NAS, so it was not possible to diagnose the problem through the software interface. Instead I had to decode the blinking lights on the ReadyNAS to deduce that the first drive had failed.

    Is this still the case in the current generation of ReadyNAS products? In fact is that the case with other NAS products?

    Losing the ability to use RAIDar and Frontview was a big surprise and I would have expected that to be flagged in product reviews. What happens after drive failure is not something I have seen reported in any NAS review, but it is very important, as most users expect to be able to access the second RAID drive in case of failure.

    Could you add failure mode analysis to your reviews, covering whether the NAS is accessible through software for diagnostic purposes (as against physical inspection of a box), and whether the remaining drives of a multi-drive NAS are actually useable one a failure mode occurs?

    Thanks,

    Brian
