1 out of 5 eggsHorrible experience

Pros: Stored files for 2 months

Cons: After a little over 2 months of use the 4th drive died, talking to tech support and getting an RMA was easy enough. They say turn around time should cap off around 4 weeks. Fast forward 4 weeks and I'm inquiring on the status and the first 3 people I speak with tell me they never got the proof of purchase (I had sent it in twice). Then they say they had the PoP but never got the drive. I reply with the tracking info that clearly states they got it and it was signed for. The two people I mention this to never return my email afterwards. I start calling in and get person after person who are going to look into it. After 3 of them I get elevated to a manager, who is going to call me back that afternoon. Two days later I call back and "oh she'll call you back in a few minutes." Like hell she will, put me on hold and go get her. "Oh she's out of the office, if you don't hear from her in two hours call back and ask for her."

This is where I'm at, and frankly I don't care if this drive ever works again. I just want to be done with Buffalo and their horrendous tech support.

1 out of 5 eggsNever Buying from Buffalo Again

Pros: It worked great for about 2 months. Hold time for tech support was not too long. Tech support was friendly even though there was not much he could do to help.

Cons: Poor quality. Drives are cheap, parts unreliable. RAID controller went bad. No way to know if the data is intact until we receive the warranty replacement unit and plug in the drives. But when will it arrive? No one knows because Buffalo does not provide tracking numbers on warranty replacements! 5 days later and they tell me it still has not even shipped yet. No way to know when to expect it. Just have to keep calling them every day or so.

Other Thoughts: With everything we purchase online we expect a confirmation e-mail with a tracking number. NewEgg does a great job with that. Why can't Buffalo do the same with advance RMA warranty replacement? I've provided proof of purchase and my credit card info to cover a warranty replacement that may or may not show up in a few days or weeks? This lack of responsiveness on the part of Buffalo convinces me to never do business with them again.

Manufacturer Response:

Cliff, I am sorry you experienced a failure with your unit within 2 months of purchase. We build our units with quality, name brand, tier 1, class A drives. We also subject our TeraStations to a ~60 hour burn in time for quality assurance. I was able to look up your record to review if there were any holdups on your RMA to explain a 5 day delay. It looks your initial call was on the 15th to setup the RMA but we had to wait on your proof of purchase, which was provided 2 days ago on the 17th. It didnt ship yesterday, so I will ship out today. please contact me if you have any questions or if you would like your tracking number.

4 out of 5 eggsSo Far So Good

Pros: Easy Setup
Reasonable Cost
Front Display

Cons: Somewhat long boot

Other Thoughts: Overall, for $540, this is not a bad drive at all. Came pre-configured in Raid 5 with 4 WD Green HDs. I happen to be a fan of WD so I was pleased. It took a few minutes to boot making me think there is something wrong, but eventually, the display does go to normal operation and the device is easily seen on the network. This one did not auto-prompt me to update the firmware like others have mentioned. It joined our domain flawlessly and saw all the AD users and groups after a reboot. Created a backup share, setup the backup software to use the device and it has been humming along ever since. Only using a single Network Port even though two are available. So far, nothing to complain about. As long as the durability is there, I can us using this drive for many years to come. I have always had good luck with WD drives. I give 4 eggs as I feel there is always room for improvement. Perhaps decreasing boot time or even maybe making it a bit smaller or increasing x-fer rates. But know that 4 eggs, for me, is a very high mark. Do not hold that missing egg as anything negative about this drive.

4 out of 5 eggsUPDATE

Pros: Works great after initial setup and install issues are overcome. Hardware seems solid.

Cons: Software needs work.

Other Thoughts: As a follow up to my previous review, we were able to interrupt the firmware update after 24 hours with no ill effect. Downloaded the ZIP file from their website and the enclosed executable flashed the firmware promptly. Highly advised to use this method instead of complying with the prompt to allow the web console to do it for you. Buffalo still needs to fix this so others don't waste a whole day of work like I did.

1 out of 5 eggsFirmware will not update!

Pros: When it works, it works great. Once you get the setup issues resolved these have been pretty solid units over the long run. Kudos for being able to get tech support on the phone without too long of a wait.

Cons: Past experience setting these up for clients has always involved calls to tech support because of something not working properly right out of the box. This time was no exception. Firmware update hung (there are numerous complaints about this on the forums) and has been going almost 24 hours now.

Other Thoughts: It prompted me to update firmware as soon as I logged in to the web console and I fell for it! The browser screen warns not to refresh the screen to interrupt - yet displays NO indication of any kind that it's making progress. Tech support says just leave it alone overnight. 24 hours later now... it is still going. This is a problem that Buffalo needs to address rather than telling me over the phone to not update it that way. Don't ship software that prompts me to start a process that's unreliable and does not show any kind of progress bar to indicate whether or not it's working. Fix it!

Manufacturer Response:

Cliff, please email me so we can troubleshoot your device. If you have problems with our update feature then I suggest that you download the firmware tool from our website for his.
The Windows/Mac tool will properly update the device each time. It will also ensure that the update is md5 hash checked.

2 out of 5 eggsTeraStation looses connectivity often

Pros: Has four (4) Seagate Barracuda ST1000DM003 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive in a RAID5. This was the primary reason I bought this unit. I wanted fast (SATAIII) HDDs in a RAID 5 at a reasonable cost. I have worked with and recommended to dozens of my customers the Buffalo LinkStation as a NAS backup solution. I even wrote a Linux based backup script that works very well for doing ftp transfers from a Fedora and CentOS based server to NAS. So I know the Buffalo Web based interface very well. I received this BUFFALO TS-XE4.0TL/R5 4TB TeraStation ES NAS 8/29/12. I installed software on my WINXP PC and I also was able to access the unit via Web browser on my CentOS server. I set it up like I have done for my customers. Turned power button on back of unit to 'manual'. I went to 'System' then 'Power Management' and made sure 'Sleep Timer' was disabled and 'HDD Spindown' was disabled. So essentially I didnt want it to go into sleep mode or spin down the hard drives

Cons: The problem has been since day 1 that I lose Web based connectivity to the NAS device and I have to restart it often while in in there working on settings or looking around in Web interface. So it's not like the there is inactivity that is causing my connection to get lost. I have an external 2TB HDD with only 130GB of data that I need to copy to the Terastation. I started copying the data the same day (8/29/12) and to this day (8/31/12) I still have only been able to copy 58GB of data. The problem is I keep losing network connectivity. Getting a 'resource is no longer available' pop up error message often. At that point the Web based connection is lost too. If I try to reconnect then I get nothing. Usually I have to wait from a few minutes to 10 minutes before I can reaccess the NAS device then resume copying data from my USB drive to the NAS device. Note that the USB drive is connected to a WINXP PC and not directly to the NAS USB port.

Other Thoughts: I was really excited to get this unit and show it off to my Linux sys-admin co-workers. I was very happy to learn Buffalo uses Linux.I work for a pharmacy software development company with 3800 pharmacies we support using Linux servers. So I work with a bunch of Linux geeks.I have the unit in the office on a Gigabit network. It has the latest firmware v1.57. Buffalo forums no help with the constant connectivity dropping problem. Any helpful solutions? Buffalo people, you reading this...???

Manufacturer Response:

Sorry for the problems you are having. It is most likely a simple setup issue. Please email me so i can help troubleshoot this for you. Most likely you have it the switch on the back set to "AUTO" instead of "Manual". The auto feature is for ECO mode where the unit will go to sleep if there are no PC's on the network with the NASNavigator software installed. If you don't have NASNavigator on any of your PC's then TeraStation will go to sleep. Go ahead and switch the unit to Manual and you should be fine.

4 out of 5 eggsGreat Unit

Pros: Easy to configure, Great Interface and Front Panel, Supports Active Directory, 4TB, Supports Link Aggregation,DFS, NFS, & works flawlessly with other TeraStations.

Cons: Not a lot of flexibility in your RAID Choices and even with link aggregation the speed is just ok.

Other Thoughts: We got this unit to use as backup. It comes with 4 1TB Hard Drives. I wanted to RAID 0 them in groups of 2 - You cant do that. Raid 0 is all or nothing! Like I said it's just for secondary backup. You can however Just RAID 5 the whole thing (now you've got data protection) and set user quotas to limit the space (DPM and VMWARE Recovery).

Manufacturer Response:

Thanks for the review. This unit is able to do the raid mode you are looking for, but it is listed as RAID 10, not RAID 0 in groups of 2. send me an email if you have questions.

3 out of 5 eggsPoor Quality Control & Support Response

Pros: Great device when it works.
Purchased in Sept 2010 to replace a 6 year old Terastation that never failed, just ran out of space.
Gave them 3 Eggs for benefit of the doubt....

Kudos to NewEgg for fast shipping!

Cons: Arrived with a loose circuit board mounting screw. Fixed that and it worked great for 3 months until I shut it down for a week. When I restarted it had a Chipset error (E20) and would not function at all.

Contacted Tech Support and found it needed to be returned (Bad Electronics Board). This is where the issues began.

They sent email to provide instructions for returning, however, the emails never came. They've tried two email addresses and indicated it could take up to a couple hours to receive. Never arrived. So I provided another email address..... Hope this one works...

Other Thoughts: Registration email was sent within seconds of completion. Why does it take so long for a support email to be sent?
Buffalo Tech needs to improve their quality control and support processes.
