drewmoney writes "A LinuxDevices.com article introduces several of Netgear's Linux-based NAS devices, technology they acquired with the purchase of Infrant earlier this year. (Here is Netgear's product page.) There are models from 1.5 TB, at about $1,100, to 4 TB, topped by a 4-TB rack-mount version. They are geared towards the professional home user and small and medium businesses. The NAS devices come complete with the usual RAID features, file-system access, and a built in USB print server. All are controlled through a Web GUI and some even offer SSH access."

- It uses the ext2 filesystem, which not only lacks journalling, but has no nice way to fun fsck (only option is to enable telnet via a fun_plug and run fsck on your mounted filesystem...blech!).
- It *still* has piss-poor unicode support.
- The current firmware does funny things if one of your drives dies and you have a RAID-1 array, such as not rebuilding the array. Some users have reported that it won't even detect a drive failure in raid-1.
- Its user/group and volume management simply doesn't work. You can't set up multiple shares and give different users different permissions to the shares. User/group management is a mess.
All of these problems exist in the 1.03 firmware, which is the latest version. My unit has also been blessed with a common hardware problem -- one of the "drive okay" blue led's died. Quite a few folks are reporting this (probably cheap leds).
About the only way to make the 323 usable and safe is to solder a serial port on it so that you can use redboot and overwrite the stock firmware. IMHO, if you're going to take the trouble to solder and manage the thing via the command-line, you may as well just plunk down a bit of extra cash and have an actual warranty. Or save the money and put two hard drives in an old computer/install linux distro of your choice. It certainly shouldn't be considered a reliable nas, and I certainly wouldn't be saving copies of anything important on it (unless you're backing the data up somewhere else).

That's $0.73/GB for this Netgear product. Almost a year ago I built a 2.5 TB OpenSolaris fileserver using ZFS for $950 [slashdot.org], that's twice cheaper: $0.38/GB.
I understand Netgear market this product for endusers without the time or the ability to build and configure a NAS themselves, but this reminds me that some of us are privileged people, because we don't have to be victims of such horribly expensive proprietary gear... We have the choice to build it ourselves and save real, big bucks.
This also shows that the storage market really have room for more competitors. At a time where the raw cost of disks is $0.20/GB and where you can build storage servers for $0.36/GB (proof: I did it), the only explanation behind the high prices in the storage market is pure lack of competition. This is one of the reasons why Google build their servers themselves: they figured out all the "professional products" out there are overpriced.

With ZFS you can also dynamically expand your pool by replacing drives one-by-one with larger ones, no matter what the current pool configuration is: combination of stripes, mirrors, raidz, raidz2. You can also expand a pool by adding a new "vdev" to it. A vdev can be a single drive or a N-drive mirror/raidz/raidz2. There is one thing you can't do (yet): dynamically reconfigure a N-drive raidz/raidz2 vdev to a (N+1)-drive vdev.

I'm sick to death of four stupid drives (Score:5, Interesting)
Good grief, can someone please explain to me what the fetish is with four drives in every single freakin NAS system on the planet? And every vendor gets the same thrill annoucing it as a "4TB" solution when only a complete moron would run these things as a single JBOD volume without any fault tolerance.
Why not five drives, guys? It's not like we are back in the late 90s when every motherboard had two IDE controllers supporting two devices. I routinely see motherboards now with five or six SATA ports. There are even splitters and repeaters that can change one SATA port into two. So why not break out and distinguish yourselfs with five drives so I can actually get a 4TB (3.8 actual *sigh*) solution AND a spare drive for the RAID set or even hotspare (if i'm feeling nervous).
Why not an even eight? How about a eSATA port so you could connect two NAS units together for expansion or redundancy? How about something like iSCSI and then let me chain as many NAS units together on a gigabit switch as I want?
I finally had to stop buying NAS units and get my hands dirty and build my own so I could actually break the REAL 3TB ceiling. I went with a SAS RAID card and an enclosure that supports 8 SATA drives out of the box. Down the road, I can get a SAS repeater and add a second 8-drive enclosure, or a third, or a fourth. Online volume expansion folds new drives in like butter.
But it's ugly as sin. It's a cheap Dell server ($329 w 3yr warranty!) whose only purpose in life is to house the SAS card connected to this ugly black metal monolith with two very tacky plastic drive enclosure racks. I don't mind sticking it in the closet of my house but I really can't stand the idea of trying to sell something like this to anyone.
But until I can pop down to Best Buy and buy something that looks decent, or is modular or stackable, I guess I'm stuck with whatever FrankenRAID I can piece together.
Eight drives, guys, how 'bout it?

RAID10 is a perfectly legitimate configuration for a great many applications; redundancy isn't the only reason people get RAID devices, you know.
Anyway, I think it's a fairly limited audience that wants more than 3TB in a cheap-ass desk-side thingy. Seriously, you'd want an 8x1TB RAID5 array on a single, "consumer grade" power supply? Might as well run it as JBOD (actually, that would probably be safe

RAID 10 *has* redundancy so I don't really understand that example as a counterpoint. Yes, there are some high-end desktops that come configured with RAID-0 arrays for performance but nobody could possibly want to do that with a NAS. I'm pretty sure the network would be a chokepoint well before you reached the performance level of unstriped drives.

And most of these consumer/prosumer NAS devices are cubes meant to sit on a desk, not rack-mounted. You can fit five 3.5 drives vertically in three 5.25 drive bays, the same amount of space as most four-bay enclosures use. So five drives doesn't seem all that unreasonable.

I'm just not so sure what's better about these NAS devices than either just running your own simple Linux server or a super-simple configuration. I'm not sure I want to trust my data to some proprietary RAIDed solution.
Every time one of these NAS stories come up, I just cringe. My experience with trying to buy a turnkey NAS like this was not good. Then I built my own [slashdot.org] for a whole lot more bang for buck. At the time, 500 GB drives were the right choice, but the 1TB might be a better deal now.
The point, though, is that with just a little bit of effort, you can easily build a system that is twice as powerful for less cost, and as you say, much safer as the data is in a completely open format the does not require any propri

Infrant ReadyNAS (Score:5, Interesting)
The ReadyNAS NV+ is a pretty interesting unit, by the way. I have been looking at it a lot lately. It's one of only a handful of midrange consumer NAS devices that include features like Gigabit ethernet (so it's not slow as molasses) and support for not only SMB/CIFS and FTP but also the native Mac file sharing protocol, AFS 3.1. (Yes I'm perfectly aware that Mac OS X has no problem with SMB/CIFS, but it's a more pleasant experience to connect with AFS, and it also works with the Classic Mac OS. Believe it or not, some people do still use Mac OS 8/9 for various reasons.)
The ReadyNAS can be configured in several different disk modes from JBOD to RAID 0, 0+1, 5, to some proprietary mode Infrant calls X-RAID which supposedly uses disk space more efficiently than RAID 5 (when you're using 3 or 4 drives). The last big positive I can think of at the moment is that it actually supports a list of UPSes so your home or office file/backup server will theoretically shut itself down safely rather than crashing hard when the UPS battery runs down after the power has been off for an hour in the middle of the night. How about that.
Unfortunately the ReadyNAS, like all the other NAS (and non-NAS) multi-drive RAID-type storage devices fails to impress me in one regard. The hardware itself that controls the drives is still a scary single point of failure. I may be protecting myself from a drive failure, but if the hardware fails you lose everything anyway! The chances of the important hardware failing is always greater than zero, and the probability that you will somehow be able to recover your data by sticking the drives into another identical device is much, much lower than 100%. So to be reasonably sure that you won't lose your entire array you need to get at least TWO of these expensive devices and keep them synchronized. This is tantamount to failure in my book.
So in the end I have kind of written off all these devices and I'm waiting for widespread ZFS support in Linux, Mac OS X, FreeBSD, et al. It's coming soon (except for Windows, I don't hold out much hope for Windows ZFS support, third-party or otherwise). When that happens it will be possible to take some generic PC hardware and create a ZFS raidz2 array that can handle losing two drives without failing to protect the data, then if that PC hardware fails you can take that ZFS raidz2 array and hook it up to some other generic PC hardware and simply do a "zpool import" and go on about your business. No insanity like losing an entire RAID array because of some stupid little glitch in the RAID hardware. Eff-you-see-kay THAT, buddy.
Unless I am completely misunderstanding the capabilities of ZFS and raidz/raidz2, it would seem that we are currently on the threshold of the first and only truly resilient data storage method that won't cost a king's ransom to implement. Any supported generic PC hardware (cheap) with Gigabit ethernet, SATA and at least 1GB of RAM will be able to become a file server that will outstrip by a country mile the performance and reliability of all these regular RAID-based NAS devices that almost across the board have abysmal data transfer speeds. Even the very nice Netgear/Infrant ReadyNAS NV+ will be completely obsolete unless they jump on the ZFS bandwagon.
Mark my words. The entire data storage industry will be changing very soon. Most folks here don't seem to see it yet but I think ZFS is going to be big. Like, iPod big, or iPhone big. Everybody scoffed at those devices at first. Well, they aren't scoffing now. I think widespread ZFS support is going to do the same sort of thing. It seems like just another filesystem at first, but it ain't.
