2 out of 5 eggsDrive Failed After 15 Months

Pros: Purchased this device last year to add a media server to our small office network. Install went smoothly, price was competitive, Newegg ships quickly.

Cons: Setup as Raid 1 to provide some internal backup. One drive now has now failed just past the 1 year warranty period. Users are having trouble connecting. We won't lose our data but I'll have to replace the drive and invest in some off-site redundant backup.

3 out of 5 eggsNot for Windows Server

Pros: Cheap

Cons: Not configurable. The device does not allow for sparse file creation and is worthless for doing Windows incremental backups.

Other Thoughts: Just don't buy it. Unless you want to waste time hacking, rooting the thing so that you can adjust the smb config, find another product.

Pros: Works great as long as it lasts'

5 out of 5 eggsUpdate, xfr speed report

Pros: I love these things, was shopping for another, and thought I'd give update review. Fantastic for home/small office storage. Inexpensive, easy to configure, reliable, fast. Superior option for small network vs. using regular desktop machine as file server -- especially if you don't know much about network stuff and want something that simply works. Have been saved several times by both the RAID1 redundancy and the backup (to USB drive) having worked as expected.

Cons: 1) I had one drive fail after 6 months. Buffalo was prompt in sending a new one. There was no data lost and no interruption in usage since it was set to mirror (RAID1) and the other drive kept running. 2) very slow file transfer when actively running a scan or rebuilding the RAID on a newly installed drive. 3) documentation is poor (lacks detail).

Other Thoughts: Report on the file transfer speed:
I just moved 321 files totaling 102,730,238,810 bytes from the Buffalo unit to my local machine. It took 1282 seconds, or 80 MB per second, from the first read to the last write (i.e., start to finish). Transfer from local to Buffalo is slower -- seems like ~55MB/s. (wire connection and gigabit router)

2 out of 5 eggsNot Good for Large Networks

Pros: Nice smaller unit. Has compatibility with both Windows and Apple networks. Capable of Raid 0 or Raid 1. Has additional features for various media storage and access.

Cons: Not good for large networks. Found out after purchasing it that it will only import the first 1000 users or groups from Active Directory. Also, share permissions can only be changed through the web interface.

Other Thoughts: Good unit for small business or home use, however it is not good for large networks even though it is supposed to be Active Directory compatible. Had to read through a lot of notes in the user manual to find out all the limitations it has that would have affected my purchasing decision had I known sooner.

5 out of 5 eggsAnother great product

Pros: I've been using Buffalo's 1TB linkstation (LS-W1.0TGL/R1 - V3) for 3 years now and it has been solid, which is why I stuck with Buffalo. I use this 4TB model mainly as a media server and for manual backups on a home gigabit network, setup as Raid 1. This unit is smaller than the previous models and the UI is more responsive. So far I'm pretty happy with it.

As far as user account access, in my opinion has greatly improved over previous models. It's easier to control and seems to actually work.

Has a built in MySQL server. I wasn't aware of that when I bought it, but it's a handy feature for me.

Cons: The older model had USB to connect an external HDD, but access was so incredibly slow it was useless. I don't have much need for that anymore but hopefully it's improved on this model.

Other Thoughts: Copying large files from an SSD, I get around 400Mb/s using a gigabit router with cat 6 cabling. (no jumbo frame)

I haven't used web access so I can't comment on that.

Older model used Hitachi drives, this one uses Seagate.

Manufacturer Response:

thanks for the review, the USB port can be slow if you drag and drop your files manually from your PC. if you attach a USB drive to the back of the unit and drag drop the file to the LinkStation then the file will transfer from the USB drive, to the LinkStation, to your PC, then back to the LinkStation. If you do this over wifi it will slow down the transfer even more. Best practice would be to use the direct copy feature. All you have to do is specify which folder you want "direct copy" to use then you just hit the function button on the front of the linkstation after you connect the USB drive to the LinkStation.

4 out of 5 eggsExcellent Product

Pros: Works great for my backups. I bought this product because of the great support I got from the company when dealing with on of their other "ancient products".

Cons: I can not get web access to work. It is not at all user friendly for a not so great tech guy. And the support for this particular portion is non existant.

Other Thoughts: The web access would be a great feature if it could be made to work.

1 out of 5 eggsShouldn't backups be reliable?

Pros: When it worked all was good

Cons: My first contact with this item was a delivery of a dead box. Not really confidence inspiring. Still, I was optimistic, these things happen with electronics. The unit was replaced within a week (thanks newegg!) and all seemed good. I set up RAID 1 and transferred all my files. Now, a mere 5 months later, and it has had an epic failure. One drive has failed completely and as a result the NAS box has dropped off the network and refuses any attempt to interact with it. The data is still safe on the second drive (thank-you RAID 1) but the only way to get to it is to stick the drive into another machine and jump through some linux hoops (the horror, the horror). All I can get now is a replacement unit, but really, would you trust your data on a system that has failed twice? This is meant to be a backup device, something solid and reliable. Based on my experience this device fails completely.

Other Thoughts: Goodbye NAS box, hello custom built Windows Server. At least newegg will be happy!

4 out of 5 eggsGood Product - Buy one

Pros: I posted a review for the LS-WV2.0. It's the same thing, just smaller. Is Buffalo publicly traded?? This product makes me want to buy their stock.

Cons: web interface needs work - messy, unrefined
