The N2A2 NAS appliance comes with a 60W AC adapter, an RJ-45 cable, product installation guide and a couple of software CDs.

In order to set up the NAS, there is no need to install any of the softwares on the CDs. Pointing the browser to the IP of the NAS and logging in with the default credentials (admin/admin) enables one to administer and set up the NAS for a particular environment.

By default, the two disks are organized and visible over the network as individual disks. The hard drive volumes may be configured in one of multiple ways:

  1. RAID0 (Striping)
  2. RAID1 (Mirroring)
  3. Linear (JBOD)
  4. RAID1 + Linear (JBOD)
  5. Individual Disks (Default)

For the RAID1 + Linear (JBOD) configuration, the amount of disk space allocated to each volume type is configurable.

In the rest of this piece, we will restrict ourselves to the two configurations of interest, namely, RAID 0 (for performance) and RAID 1 (for redundancy).

On the whole, the setup process is painless. The NAS is also DLNA certified and offers a host of other features like FTP and web server as well as Torrent services. The LG N2A2 NAS offers the right balance of features and options for the home consumer.

    Sorry to hear that. Exactly the reason I will always build my own. Those small fans are way too loud. Reply

    Would like to see some power tests in these home NAS reviews. Do these things have some sort of sleep mode? That's the main reason I can see for going this route vs just using some old hardware laying around. Reply

    The power numbers are in the final section.

    ~21 W for full load
    ~14 W at idle

    There is also a configurable 'full sleep when no access' mode where it consumes less than 1 W. It is woken up on access over the network.

    I do have the N2R1 (actually I gifted a second one to my father since his previous ICYBox was a huge loud piece of crap). It is somewhat fast, silent, has a nice feature set also including the DVD or even BlueRay write and runs a modified Debian which allows for some nifty tricks like the use of rdiff-backup. I also do have other soft- and hardware RAID systems running.

    Doing software SATA RAID on an Intel based system /may/ be faster and allows using the very useful LVM but is far less stable due to funky link resets from which md sometimes won't recover, sucks far more power and is nowhere as easy to administer -- not that I'd care, but you get the idea...

    Iff I ever decide to do another Linux RAID it'll prolly have a 3Ware (or similar) Hardware RAID controller, again. Other than that I'd go for another LG NAS or some more expensive brand...e

    "The disks in the N2A2 can't be replaced by the user."

    Doesn't that somewhat undermine the usefulness of RAID 1 for an end-user?

    Yes, it is inexcusable (as I have mentioned in the review).

    However, data recovery is possible by the end-user. (I have outlined the steps in the penultimate section)

    I assume that the N2A2 will let you copy data from it with one disk degraded. When I read the article the first time, I (hopefully) mis-understood that you HAD to tear the unit apart to recover it. Re-reading it I see that it was more "just to see if it could be recovered" in the event of a board failure.

    I guess I can see from their point of view to simplify support - maybe they don't want to deal with HDD compatibility. But like you imply that didn't seem to be a problem for releasing the N2R1D. It does seem strange to need to RMA the entire unit for a bad disk.

    Then again, I'm assuming that's how they will handle HDD failures?

    Regardless, thanks for the article - especially the recovery tear down.

    Yes, the unit was torn apart to test both failure scenarios at once.

    With HDD failures, the end-user can recover the data while in the degraded mode. For motherboard failures, I am not sure what LG will do in terms of data recovery (but the end-user can tear down and recover from the hard disk -- as covered in the data recovery section)

    I am not sure why LG decided to introduce this type of NAS into the market. As a networked hard disk, this makes more sense (but not as a NAS competitor to D-Link's and Netgear's offerings in the same price range).

    ... I'm also not sure what to do. or just continue to use my normal pc and setup intel raid.
    A NAS with decent perfromance figures, eg. one of the QNAP or synology types with an atom processor are about the same price here as a DIY NAS with a Core i3. Note that Core i3 is only like 40$ more than brazos/atom build. That includes Chenbro case (=expensive). This is were DIY fails because these "small server parts" are very expensive and I don't have space for a second "normal" pc case.

    If you have the cash to spare, I think the 'buy' option is the preferable solution (compared to the headaches that building your own system brings)

    Also, for most home usage scenarios, PCs are an overkill for NAS solutions. A simple hard disk serving content over the network with the help of an embedded NAS chipset (like the one from Marvell) will be much more power efficient and easy to manage.
