snydeq writes "InfoWorld's Desmond Fuller provides an in-depth comparison of five entry-level NAS storage servers, including cabinets from Iomega, Netgear, QNAP, Synology, and Thecus. 'With so many use cases and potential buyers, the vendors too often try to be everything to everyone. The result is a class of products that suffers from an identity crisis — so-called business storage solutions that are overloaded with consumer features and missing the ease and simplicity that business users require,' Fuller writes. 'Filled with 10TB or 12TB of raw storage, my test systems ranged in price from $1,699 to $3,799. Despite that gap, they all had a great deal in common, from core storage services to performance. However, I found the richest sets of business features — straightforward setup, easy remote access, plentiful backup options — at the higher end of the scale.'"

You're technically correct (the best kind of correct). But... While I agree a hot plug bay may be a nice idea, really, on a home NAS, what do you want to hot plug all the drives for? If you're trying to fail a drive and rebuild the array you probably aren't in a position where you want to be using it continuously through the rebuild.
What's the use case for hot plugging the drives?

And yes I have used a cheap dual drive NAS while it was rebuilding the array. It was slower but still functional.
Hot swap cases make drive management much easier. Drive 3 of 5 needs replacing? Forget tracing cables back to the motherboard just pop out drive 3 in the array and replace it. This also means I can get someone else to do it even if it means walking them through it over the phone.

I have a DS1010+ 5-bay model and absolutely love it. It's got 10TB in it right now but I may replace the drives with 3TB models eventually. With a dual-core 1.6GHz atom and 1GB DDR2 ram it easily reads and writes at 100+MB/s via a RAID5 array on my simple home gigabit network.
Also the new NAS' that are Intel-based can run most CLI linux servers and programs which is great. You may need to add more RAM if you run lots of heavy servers or have lots of concurrent users but most have spare ram slots.
The best thing I find about Synology is their every updating and cutting edge Web GUI. They are already using HTML-5 features to support things like dragging and dropping files right into your web-browser to upload files to the NAS remotely.

Having 3 network cards and enough space for 15 drives makes up for the few hundred extra dollars you pay for a DIY NAS. Plus, a DIY NAS has a lot more flexibility than the consumer grade NAS.

Basically the majority of cheap NAS units are a Linux box with some storage, and anyone who doesn't consider them a viable alternative doesn't have the chops to build one.

If you manage to build a storage server that pulls a few hundred more watts of power, you must be doing something very wrong. Even a gaming system with a 2600k and a HD6870 draws 75 watts at idle from the wall socket, and that's roughly the worst possible setup for a storage server you can get.
If you just want 10TB of storage capacity to go with your laptop, setting up a Linux box and sharing it out is dead easy. If you want a full server then the NAS boxes don't deliver that. But I agree, there's a pretty

I would agree with that. However the best scenario I've tried with a Linux machine is using a software raid (or LVM) on a bunch of disks and then setup a iSCSI target, especially convenient in a virtualized environment. Network cards are cheap so it's easy to add custom multipath.

Reading about Linux's disappointingly lame MD system gave me new respect for Synology's devices, especially for the SOHO environments for which they're suited.
For a larger / business application, ZFS totally rocks, but Oracle has decimated Solaris' visibility, so one is left with no good options.
I have yet to see a typical scenario where the bottleneck is at the back-end (ie: md). The sluggish part is always at the frontend; the higher you get on the OSI layers, the more you need a robust interface. And at this level, Linux is terrific. Having a custom storage machine allows you to put more power where you need it, something that is not possible with a COTS device.

When you're just building a home/small office NAS, you don't need a high-performance RAID card - software RAID is more than enough. Especially considering the price of those things.
maybe but not all boards have 8 ports and some that's 6 chipset and the other from a add on sata chip also the build in software / fake raid likely will not work across 2 different chips like that. And even with 8 ports you still need 1 for the OS disk or you can mix the OS with the data drives.
redundancy you may want raid 6 on a raid card and not on board fake raid and most south bridges only have 6 ports any ways.
8 hard drives is not enough to justify RAID 6, unless they're EXTREMELY unreliable drives. Especially since that cuts down your storage capacity down to 12TB - not that good.
RAID 6 is only needed when it's possible for a drive to fail, and then for another to fail while the array is still recovering. There's no point in doing it with only 8 drives.
8 drives in raid 0 is a major risk. Raid 5 uses less space.
Also some low end MB only have 10/100'.
True. But then again, how many switches and computers are still only 10/100? Maybe you don't, but I still work daily with stuff that maxes out at Fast Ethernet.
Plus, a $115 mobo isn't "low-end", at least by my definition. It's a fair assumption that if it has 8 SATA ports, you're going to have 10/100/1000 Ethernet.
The case needs to have room for 8 HDD's + a os disk and good cooling.

Yeah? For $30 I can also add a nice SD/MicroSD card reader. And it would be just as beneficial to the system. Just because RAM is cheap, doesn't mean you need to cram absolutely everything full of it.
maybe but not all boards have 8 ports and some that's 6 chipset and the other from a add on sata chip also the build in software / fake raid likely will not work across 2 different chips like that. And even with 8 ports you still need 1 for the OS disk or you can mix the OS with the data drives.
Once X79 comes out, you'll have 10 ports, naturally. In any case, software RAID, at least under Linux, can handle disks on any widely incompatible set of chipsets. As well as separating the OS onto a disk partition on just one drive.

It's also extremely useful if you run into an unrecoverable read error while trying to rebuild the array.
A lot of standard mechanical drives have an unrecoverable read error rate of about 1-in-10^14 bits (or 1-in-~12TB), meaning you're getting into some pretty nasty chances of hitting an URE on at least one of your disks when you're trying to rebuild the array after a disk failure with a decently-large array.

Yeah I figured that out a long time ago. I figure the only people that buy that crap are people that are lazy, want a really simple solution, or do not have the expertise to do it themselves. That is to say you take one of these pre-assembled NAS, plug it in network, do a wizard, done. For a small biz with no tech support, maybe an option. Also most of the bigger NAS support hot swappable drives, which is nice... thought if you spent about 120$ rather than 40$ on your case you can get hot swappable drives a

I got a Fractal Design Array R2 Mini-ITX NAS Case which is gorgeous, takes 6 HDD in a small case. MB is Sapphire Pure Fusion Mini E350 AMD Dual Core E350 which is very low power, 5 x SATA III + 1 eSATA II, USB 3, GbEthernet.
FreeNAS 8 supports the hardware, and ZFS filing system is reliable.
Not enterprise level, but excellent for home use.

...and you should budget for 8GB memory to run the ZFS filing system properly. Oh, and FreeNAS runs from a 2GB (min) USB stick, doesn't waste a HDD.
To soft-start the investment, you could buy the MB + RAM first, set it up in a cardboard box with a spare PSU and 5 any-size SATA HDDs you have kicking around.

There is no mention of speed, performance, file copy replication, the ins and out of each solution, just a list of features they all share and how the author went about determining them at his whim. Without metrics this article is just a sales blurb for links. Other websites do it better: Storagereview for one, Smallnetbuilder is the other.
Another wretched sales brouchure disguised as a review by Infoworld.

It's definitely more work to set up than a pre-built appliance and I wouldn't use it in a production environment but it has some advantages and works well as my media server. I particularly like that multiple drives developing a few bad sectors won't render the entire array unrecoverable. That's a bit of a concern when combining multi-terabyte consumer level drives. I currently have 20tb of fault-tolerant storage with room for another 6tb before I run out of ports. With more ports and a larger case, I could go up to 40tb.

Yes yes yes I've seen how it is done with ZFS, even played with it myself, but it is NOT the same, it is NOT as seamless, it is NOT as simple. With unRAID I add a drive and that is basically it. It just starts saving data to it as if it were a JBOD.

The metrics were using different raid types from one solution to the next, some say RAID10, some RAID2, etc...

Use GlusterFS http://www.gluster.org/ [gluster.org] for redundancy spanned across one or more JBOD machines for a much easier hardware and data upgrade path. Use oVirt for easy set up http://www.gluster.com/community/documentation/index.php/GlusterFS_oVirt_Setup_Guide [gluster.com]. Mount GlusterFS directly to your clients or export via iSCSI target, fibrechannel target, FCoE, NBD, or traditional NFS for a more advanced shared storage solution. And you can still run more of a NAS type setup with CIFS, WebDAV, or the like.

Dear Slashdoters. I know that you can build a better, faster, cheaper NAS that will perform fellatio over SSH and wipe your ass for you.
But, I don't care... at all. According to you, I overpaid for my two NAS devices, a Drobo FS (serving media) and a Synology DS211+ (photo backups (profoto)). But I'm exceedingly happy with them. Transfer speed is sufficient on the Drobo to serve 1080p content to 2 tv's and an iPad simultaneously, and the Synology keeps up with my image editing software just fine. I've upgraded the drives in the drobo once so far, and just like their videos claim, everything just worked. The Drobo survived a drive failure last year, in the middle of 'movie night,' and video playback from the drobo was unaffected. - I'm glad that these NAS devices were reviewed, but I can't imagine why so many have come to this thread to post their server builds. The people, like myself, buying these NAS devices are buying them so we don't have to build our own servers.

I think the only problem I have with Drobo is the horrifying warranty options. For a device that has roughly 80% markup, I think it's attrocious that it has a hardware warranty period (1 year) lower than a cheap USB hard drive from just about anyone else (2-3 years). Especially given that once you're out of warranty, a hardware failure ANYWHERE in that device isn't really recoverable from without going out and buying a new Drobo. You can argue that it's unlikely to fail, but I think that, if they really sta

The ability to pop out a smaller drive and replace it with a larger drive is amazing - that is simply how technology is supposed to work. I have the Drobo FS at home and the DroboPro FS at work. Having used them for about a year and having tried to make them fail before I moved them into production, I'm very happy with their reliability and performance. (More on performance in a second.)

My own AFP experience with QNAP was terrible, due to the dodgy FOSS stack - I forget which one - that was included.

I ended up with iSCSI between the QNAP and the Mac OS Server (ATTO iSCSI) and serving AFP from there, with a 5x speed improvement.
Was I doing something wrong? It doesn't seem to match the AFP figures in the article. Anyone else have similar awful real-world AFP performance?

They use JFS on debian.. You can easily add the filesever software of your choice (Samba, Netatalk, NFS, etc.)
On the hardware side they use a Intel mainboard with a Intel Core 2 CPU, a PCIe SATA 2 Controller and 45 SATA 2 discs (each 1.5 TB). They put it in a custom enclosure, the 3D model is available here (25 MB ZIP archive) [backblaze.com]. This all costs less than 8000€ for 67 TB (discs included!).
There is also an update [backblaze.com], where they get 135 TB for less than $8000.

Unless you are absolutely phobic about exposure to harrowingly technical terms like "raid5", you should approach the drobo with notrivial caution.
They are quite pricey for their size and performance, which has historically been pretty tepid. Probably worse than that(which is a set of vices shared with quite a few other underpowered NAS units), is that their "BeyondRAID" system makes up for some powerful features by being Just Fucking Weird in some annoying ways.
