1 out of 5 eggsProblems with Buffalo Tech

Pros: Works well when working

Cons: Power supply failed after 13 months. They do not sell parts. Told me I had to purchase a new unit with drives.

Other Thoughts: The Terastation is a throw away product as Buffals will only sell complete unit with drives. They do not sell an empty box or power supply.

4 out of 5 eggsSatisfied after using it a couple years

Pros: RAID5 configuration

Cons: one of the drives failed, but I bought a replacement for under $100, and installed it, reconfigured my RAID5 array and didn't lose ANY data, which is the main reason I bought the thing after many IDE drive failures on my desktops

3 out of 5 eggsAn OK Product.

Pros: Good Storage for the money. Raid 5 is great. Design is compact. Pretty much Plug-N-Play. Use it as a backup for large DV projects as well as central file storage for my Home office. Overall just Average compared to other products like it, just a bit cheaper.

Cons: Slow. Same network PC to PC/Server transfer at about 1GB per min. To the TeraSTation it's about 3 min. So compact that it's a task to swap a drive. Slow IDE drives need more cache. Should have gone SATA. Their configuatrion of the built-in Linux OS is very limited. No Defrag ability. Bad limitations on passwords on the accounts. Sleep mode is just that. It goes to sleep even if it's busy. To do the NTP setup you had to open your firewall, not good.

Other Thoughts: Kinda wished I'd built my own server with SATA drives on sleds. Would have been much more flexible and faster. I manage nearly a hundred machines in 6 countries and decided to try this out in my home office. It does that job OK but I wouldn't put it in my other instalations.

1 out of 5 eggs

Pros: Raid 5 capability, NAS, backup to external USB drives.

Cons: I have gone through three of these. The raid array continues to fail. Fortunately, I have always had backups.

Other Thoughts: Technical support takes forever to get a response and at times I have had to leave a message for them to call me back. Unacceptable in my opinion. Will not purchase any Buffalo products in the future.

1 out of 5 eggsrubbish

Pros: lots of storage, raid1, raid5

Cons: in the bit over a year i've owned this device, i've had to replace 2 of the drive, and it's looking like a 3rd is about to go out as well. thankfully i've had both pairs of drives set up as raid1 since i got it. i intend to purchase something else as soon as i can find something that doesn't die regularly, and turning this device into perhaps a piece of art.

Other Thoughts: if you value your money, look elsewhere for storage.

2 out of 5 eggsWhat a nightmare

Pros: As a professional photographer, this appeared to be a great solution to back up my digital images and other important data. Raid 5 is a very strong platform for valuable data.

Cons: The Terrastation has been a nightmare from the beginning. After about 5 calls with 30+ minute hold times, they finally sent me a replacement. The replacement had one hard drive fail immediately. Ended up swapping my original 4 drives into the new case. Still have many issues. Connectivity is highly unreliable. Keeps dropping the network connection and Buffalos response is "you can always access the terrastation through the web browser".

Other Thoughts: The idea is great, but I would not recommend this product to anyone. It should be called a terrible station! I should have heeded the other reviews!

5 out of 5 eggsGood deal

Pros: This is a great deal for the home, small office, or home office. Plug it in and 5 mins later you should be good to go. Works great as a server.

Cons: The write speed is a bit slow using RAID 5, but really, for most uses for this, you will not have a problem.

Other Thoughts: Great deal for your dollar.

2 out of 5 eggsYou get what you pay for

Pros: Self contained unit

Cons: About everything else

Other Thoughts: You really do get what you pay for considering that after the cost of the drives, you really only have few hundred dollars left to work with for the rest of the components. I think Buffalo should consider putting in faster, higher cache drives, a motherboard with a faster bus and allow sleep mode to be disabled if they want to keep their name in the storage space. For literally a few hundred dollars more, you can build a 1.2TB SATA box that will run circles around this thing.

4 out of 5 eggsWorth your time and money

Pros: About 700GB of capacity when using raid 5. I use three of these at work and haven't had a problem with either of them. Unfortunately all 3 of them are full and we need to buy more. At this price buying multiple units is better then buying a larger 1.6 or 2.0 TB unit. I had a computer w/ a TB of storage and that was fine, but if the computer was down for some reason then the data couldn't be accessed from the other work stations. These are Linux based, not Microshaft and I find them to be a little more reliable. Plus they use Western Digital Hard Drives which is one of the better companines IMHO

Cons: It is slower then transferring data between two computers on a GB network and if a drive did fail (which none have) it would be a pain to change compaired to the pro versions with the removable racks.

Other Thoughts: If you need a lot of storage and dont want to spend too much this is the way to go despite what the reviewer below me says.

1 out of 5 eggsNot worth your time or money

Pros: RAID 5 data protection.

Cons: Very slow even on GB ethernet network when tranferring files from a fileserver to the Terastation.
Very poor quality, poor customer service, bad return/replacement warrantee policy.

Other Thoughts: Do not buy it! I had the unit for only 3 months and it booted the first two times fine. I was able to transfer most of the crucial data to the array, but it took 72 hours over GB ethernet from a Linux file server to the Terastation and it has never booted since. It took a some time to find any information on the Buffalo Tech website that explained what the flashing red light meant. I called Buffalo several times for a replacement and was on hold for hours each time. When I finally spoke to a real human, I found my alternatives are to send in the unit with all of the important data on it to perfect strangers or to FAX my credit card information to them so they could charge me and then send me a unit to swap the drives into and send back the defective unit and then backout the charge to my credit card. They should just send me a driveless unit to swap with, but Buffalo won't do that.
