A loss of data can be prevented in normal operation, but all of the measures that can be taken do not replace the need for regular backups. The use of at least two hard drives in a RAID 1 configuration enables the mirroring of information should one of the drives fail.
If you take both of these criteria into consideration—lower power consumption than a full-scale computer and the redundant storage of data—you will soon come to the conclusion that a NAS device is the best possible compromise. This storage technology has already been used by large businesses for a number of years, and is now making its way into SMBs and even into home environments.
Saving To Two Hard Drives
NAS devices used in businesses generally contain at least four hard drives. To accommodate smaller organizations, particularly with regard to price, NAS devices for the Small Office / Home Office (SOHO) sector and the private user are now being offered with one or two hard drives. In both instances, the potential buyer is still able to purchase units with hard drives already pre-installed by the manufacturer. Pure NAS cases without pre-installed drives can also still be purchased, thus reducing prices even more. It is even cheaper if you decide to go for a NAS case with just one hard drive slot. For the purposes of data security, a NAS device with two drives is preferable to one with a single drive.
RAID Modes For Home Use
Until very recently, RAID technology was mainly used in large companies and mostly required special controllers that are not only very expensive, but also require specialized knowledge. Now this technology is being included in more and more lower-priced units. The implementation of RAID capabilities into hard drive controllers on motherboards means that this technology is also available for private users. And this can also be seen with NAS devices. The user interfaces have been made more user-friendly. In addition to simply setting up drives and user accounts on the NAS devices, it is also possible to easily configure the various RAID modes without the need for a storage background.
In order to see how capable these NAS devices really are, we have decided to use the Maxtor Shared Storage II as an example. The following pages will reveal the impression this unit left behind, and how it performed in our tests.

kwl review for this device. I wonder though if it allowed for mtu/jumbo, vpn security config n such. Prob not but that woulda been a nice touch.
The Silent Majority
These home NAS storage solutions need raid 5 and support for at least 4 drives. Until then my old AMD 500 will continue to chug away...
"But the fact that a user may wish to replace the drives has not been taken into consideration. Should a drive fail and you need to replace it yourself, you’ll have to take the unit apart and break the warranty seal."
If a drive fails and it's still under warranty, it would only seem logical to invoke the warranty protection and get a free drive. If a drive fails and it isn't under warranty, then breaking the warranty seal wouldn't be a problem. Doesn't seem like a particularly important detail.

"...And so, with a clash of lightning that split apart the heavens, and with a mighty voice, God said unto Abraham: 'Click on the image twice you doofus!'".
I do agree that clicking on the image once to get the main image page, and then a SECOND time to get the full-sized image is stupid, but if they were to insert the full-sized image in the main article, the article would be pretty hard to read through.
I had one of those little warranty stickers on my old Mactor One-Touch. With a razor and some patience you can get that sucker off without breaking it.

Except that this will involve sending your still perfectly functional drive away, where it will be perused by whoever while you have no access to it yourself. Not an acceptable solution to me. This is yet another FAIL solution for home NAS, I'm afraid.

the problem is you'll have to do without your data while you wait for the warranty work. do you really trust sending out your one good copy?
Let me see...Raid 1 means you can replace a failed drive with a new one and the second drive (the "mirror") still contains the data. But now, you have to replace the failed drive so the mirror can be rebuilt...but you cannot without voiding the warranty. Do I have this straight? If so, this is simply a disaster waiting to happen. Especially with the high drive failure rate reported by customers. Still waiting for a good home NAS.

Buy your drives.
Call it a day.
Performance is lackluster at best, especially in raid-0! Let me rephrase, performance is TERRIBLE.
The chances of the working disk getting damaged while shipping the whole box back for a single failed drive are WAY higher than the chances I'll damage it opening it, but considering the literacy of the users of such a slow NAS... I'll stick with my homebrew NAS kthx

Use Raid 10 it's just as secure as RAID 5. you need 4 drives for RAID 10 however. use the last slot has a spare.
You gotta go e-sata for performance. Then just share the drive for other users to access it. At the minimum you need a gigabit connection but for that to work you need gigabit through out your house.
Otherwise you're stuck at 100Mbit. USB is 480Mbit for a comparison of theoretical throughput.

eSATA will only work for computers w/in a few feet of the NAS. GigE through the house isnt that hard, just make sure you have a GigE switch somewhere, most recently built/wired houses have GigE wiring, its been pretty standard in terms of wiring for some time now. Cost of USB wiring throughout the house pretty much knocks that out. So GigE or .. well to be honest the performance on this system was so bad it'd be fine on 100Mb with the exception of only one graph which showed > 14MB/s results.
What were they thinking when they implemented Raid-1? The whole point is to be able to easily replace the defective drive, have the NAS rebuild it as soon as possible, and have some peace of mind that your data is again sort of safe. Now they want a customer to entrust their valuable data and send it off to who knows where to be viewable whoever.
Thats a deal breaker.
I suppose my imperfect knowledge of RAID arrays doomed me. I assumed that you would still be able to remove the data from the one working drive. Big fail on my part, it seems.
Sure you can remove the data from the working drive but that would entail a user who has more than 500GBs of it to keep a backup drive for a backup solution. HDD are pretty cheap now a days, but nonetheless that in my opinion defeats the purpose of having raid1.
I've had one of these units (the 320GB version) for over a year. I was after a simple, small, low power NAS box that could sit on my home network to store & share my families MP3 collection. I only use the Web interface to set it up (I don't load any software on my PC/s) and don't use the raid mode at all.
It works OK, but it is slow and has some quirks with media player (9/10/11 on 4 PCs) when playing files (VLC doesn't seem to have the same problem though). I also automatically clone my work to the unit every hour just as another repository. The unit gives the perception that it's underpowered (CPU wise, I assume it's some embedded processor running linux?)
One of the main reasons I bought this unit was that is was cheap & had an external USB HDD & Printer connector. I haven't used the printer port(yet), but I did buy an external eSata/USB2 drive enclosure in which I put a 500GB drive. I can plug this into the NAS box for extra storage or I can also plug the same unit(when required) into the eSata port on a couple of my PC's if I need some temporary extra(fast) storage(sometimes for video editing/converting across drives).
I'd give the unit 7/10.
My smaller/earlier Maxtor SSII has a severely disfunctional mediabolic UPnP server that is compatible with pretty much nothing and even fails tests in Intel UPnP validation suite. You seem to have just given the UPnP server in this NAS a "pass" based on its documentation... you really ought to test it and tell us if actually works.
For the purposes of data security, a NAS device with THREE drives is preferable to one with only two drives. Raid-1 with 3 drives FTW.
I don't know why it's so difficult for an empty Raid-1 box with 3 drive slots and GB LAN at a reasonable price to come to market. You would think that a simple Raid-1 controller chip in a plain black aluminum box would be cheap. Not $500.
Just reading about this NAS solution in other pages a found the comments and reviews from amazon customers: selfexplicatived. http://www.amazon.com/Seagate-STM3 [...] B000GOUE3S
