Pros: Already posted- it was wonderful for a VERY short period of time.

Cons: Ive had this unit up and running two weeks now. Today, out of the blue while reading a file, the NAS just disappeared from my network list. I have reset and powered down and done everything short of taking it apart and it is just gone. I even switched cables AND network hubs. I now have to play the warranty game with Buffalo. I guess it was too good to be true--look for something more reliable.

Overall Review: From amazing to junk in less than a blink. Here is Buffalo quality.

Pros: FAST, inexpensive, good build quality. I'm using it with macs and PCs on a gigabit network. Stays cool and quiet. The On/Off switch is a nice implementation. When you toggle it OFF, it runs through a proper shutdown routine of the NAS, not just cutting off the power. Fast Web UI.

Cons: if not running DHCP, it's a bit hard to get setup using a static IP. LED is a bit bright, can't lower the brightness/shut them off. The AUTO power feature isn't recommended. The NAS seemed unreliable when this was set.

Pros: Nice looking unit, good when it worked. Tech support had no wait time.

Cons: Like many others the firmware went bad. I don't feel I got good value out of my purchase. Recovery process could be better.

Overall Review: I've had some of Buffalo's routers flashed with ddwrt and they have worked really well so I gave them a chance for a NAS. I have local backups of my virtual machines and then 2 others at an different offsite colo, kept it cool but it just died anyways. Under 1 year but the data is important and I can't give it to buffalo so I'm stuck with probably a paperweight. My personally built freenas setup was more expensive but much faster and more reliable.

Pros: Connected to customers network and the preset share was easily accessible. Speed seems good - am backing up several workstations to it with Acronis TI. I did not evaluate the bundled NovaBACKUP software or other functionality.

Cons: None.

Pros: None

Cons: Always needed rebooting. Died within 4 months.

Overall Review: Buffalo support impossible to get a hold of. Finally found someone who confirmed hard drive dead. Buffalo wouldn't recover the data, but recommended a partner data retrieval service. $2,100 later, Buffalo told us they wouldn't replace drive since the service opened the case and voided the warranty. Wouldn't send the original broken case/hard drive back either.

Pros: Fast, reasonably priced, gigbit ethernet, nice build quality and attractive package. I purchased 2 of these units for file sharing in an Active Directory environment to allow various AD groups to be able to easily share documents. None of the content is particularly critical or sensitive. Nonetheless, I assumed I would be able to restrict access based on AD group membership.

Cons: Remember what happens when you ASSUME. Active Directory support is useless. By default, everyone has read/write access to a shared folder. If left in the default mode you can only restrict user or group by giving them "read" access. Yup, there's no way to deny someone from having read access. The second option is to give the shared folder "read" access and add AD users or groups and give them "read/write" access. Again, no way to deny access. I can't think of many scenearios where I'd want all of the users on my network to have read access to all folders. Subtract 4 stars. Then, there's the documention. I didn't expect much here but the docs are worse than I expected. Subtract one star, which technically leaves us at 0 stars.

Overall Review: So close... Buffalo, if you're listening: this *could* be an awesome device if it had real "Active Directory Support"

Pros: The concept is great. Firmware not easy to use but not that difficult to figure out. When it works, it is great way to back up files or store files you don't need very often. Setting up password protection is not straightforward and only one computer can access password protected data at one time.

Cons: The unit failed after 2 years. The firmware crashed and could not be recovered (even after following some complicated instructions from their web site). I was copying files to the unit when it just stopped. Error code indicated it was the firmware. I also had a Linkstation Duo fail after about 9 months. Only a one year warranty. I will try to remove drive (no easy way to do so) and see what I can recover.

Overall Review: I would not purchase again.

Pros: Fairly fast, cool, and quiet.

Cons: Unit died 1 year and 4 months after purchase. Warranty is only for 1 year. I am not buying another one of these.

Overall Review: Documentation is poor, especially explanation of the error codes the LED light shows.
