5 out of 5 eggs

Pros: Worked good out of box, easily hits over 50 MB/s transfers in a gigabit network, saw 90+ MB/s doing ripped BD movie ISO's

Cons: can't really administer the darn thing and I had to reset the "share to ps3/xbox 360" option every time for a while in mid 2012, also the first week it spent "optimizing my media" was harrowing - afterwards it worked wonderfully

Other Thoughts: I'd still use it but I prefer to get all new hardware every 2 years when it comes to file storage, repurposing the hdd's for hotter, more volatile data (scratch disks n' such)

3 out of 5 eggsWas great when it worked...

Pros: From a pure NAS perspective, this device does all that it needs. LAN connectivity is good and haven't had any issues whatsoever with the drive health. Not a bad deal for a 2-drive NAS. I have two 2TB drives mirrored.

Cons: The product really fails on two primary dimensions for me: 1) the DLNA connectivity to Xbox or whatever device you have leaves A LOT to be desired. The on-the-fly and pre- transcode settings never work it seems and the files shared are grouped in one massive list - there is no way to traverse your folder structure.
2) The pogoplug software is buggy and when it did work the connectivity and UX were so bad I only used it when I absolutely needed to. Now my device doesn't connect at all to the cloud and this appears to be a common issue that requires calling pogoplug and cloudstor support to get them to reset the device registration on the back end. That's frankly not worth my time for a lackluster feature set so I'll be shopping for a new device now with a larger array too so can take advantage of the better RAID configurations.

Other Thoughts: Buffalo - I like your product, but your firmware software needs some improvement. I haven't seen an update in over a year. This device will be relegated to auction or as a backup to my backup if I can't reuse the drives in a new NAS product.

1 out of 5 eggsDon't buy for a Raid 1 backup

Pros: None

Cons: This only comes with one HDD and it's a green label WD HDD. You can't use a green HDD to create a raid. You need to have a red or black label HDDs to create a Raid 1. Will be returning!

5 out of 5 eggsUnbeatable Budget NAS if you upgrade the drives

Pros: Two drive bays for mirroring (or striping if you are crazy).

Much better hardware spec's than anything else in this price range.

PogoPlug makes (almost) everything easy!

Cons: A Green drive? Really? I thought this thing was all about performance!

PogoPlug software couldn't get an active synch going between an external HDD and this device, no matter what. Finally had to just assign the NAS a drive letter with PogoPlug and use Microsoft's free SnycToy to make it work.

Adding a drive and formatting it takes no time at all. Checking the drive before it can be used takes all day and all night!

Only 1 year warranty. Doesn't Buffalo have more faith in their equipment than that? We replaced the OE drive with new ones with 5 year warranties instead of only one absurd year.

Other Thoughts: So the first thing I did for the customer who bought this rig was pull the Green drive out and put two 2TB WD Black drives in its place, without slowing down to think that the firmware lives on the internal drives. The machine was then rendered unusable.

I put the Green drive back in and added ONE of the Black drives with it. The next day it was done setting up the Green drive and Black drive in a mirrored array. I pulled the Green drive and put the other Black drive in. One more day later we finally had a RAID1 array running and the lousy OEM Green drive decommissioned.

The purpose of this particular NAS was a backup of the backup. That is, Backup Exec runs on my customer's server and backs up to an external HDD. After the backup completes, SyncToy runs and synches the HDD to this NAS, which lives at the business owner's house so there will be a surviving backup if the building is hit by a meteor.

The whole system works great, thanks to PogoPlug and SyncToy.

2 out of 5 eggsWorst DLNA feature set

Pros: Easy setup, I mean really easy. Remote access is easiest thing ever.

Cons: Dear Buffalo. This Nas is a DLNA fail, I mean the file titles are wrong, my wdtv picks it up but when I select a movie it plays a different movie, sometimes I get the error no files found in the folder.

Next launch windows media player and the pogoplug shows up as media server, but once again, no videos, no music, no pictures are found by media player.

I absolutely can't stream any movies, and the new files added are not refreshed until I restart the unit, why? I mean why is it so hard to get the most common feature the most common feature on it right?

Other Thoughts: I regret purchasing this becuase this is a big giant fail when it comes to media server features. Is it really that hard to get that big of a feature right on this product? I am stuck with it and here is to hoping that buffalo will get their firmware together and fix these issues.

Pros: If you're looking for a NAS that works similarly to Dropbox that you can access anywhere around the world on your "My Computer" Window's Explorer or Mac "Finder" without having to use a pesky Web Browser interface, LOOK NO FURTHER.

For Remote access a typcial NAS often restricts you to using a web browser to upload and download files. As a frequently traveling designer, I have to work on my files often (ie: CAD files, Photoshopping, etc.) and do not want to deal with the hassle of first downloading the file from the web browser, then working on them, then re-uploading them again through the web browser.

With the Buffalo NAS, I simply have to download the POGOPLUG software, and it Maps a drive onto MY Computer which acts and works EXACTLY like a Local HardDrive. I know that you can map a network drive without using POGOPLUG, but that technique only works when your computer is within the Local Area Network aka my Home, thus not when I'm overseas!

A Great Buy, highly recommen

Cons: The embedded software is SIMPLE. It doesn't have much in terms of an extremely comprehensive software package as is offered by Synology, etc.

Other Thoughts: For the working Road Warrior!

4 out of 5 eggsGreat Product!

Pros: Unit was exactly as expected, and set up between multiple computers on my network was not difficult.
Set up with mobile devices was very easy to do, and the iPhone app even allows you to watch videos and listen to music stored in the drive! If the video wasn't compatible - it would convert for iphone compatibility.
Pricing of the unit with rebate (at the time) was excellent!

Cons: As was the case with some other reviews, the access time is a little slower than what I would have liked.

The unit is tricky to set up, as once connected to the network and internet, it needs to flash update, before you can start accessing it. There was no indication of this in the users manual.

Other Thoughts: Over-all, a very good unit for the price.
Software is decent.

Will need to obtain a second drive to test Raid performance.

5 out of 5 eggsCurious

Pros: I got this as Christmas Present from my parents -I'm really hopeful it will work for my household

Cons: there were no instructions of any kind in the box except for a tiny Quick Start Guide - while I'm sure I can figure it out - I wondered if this was normal.

5 out of 5 eggsWorks well for me

Pros: This thing is fast for the price! Windows Backup maxes out at 32 MB/s though regular file transfer runs slower (~25 MB/s) due to some housekeeping the NAS does in the background. Be sure you have Gigabit Ethernet to take advantage of the speed.

Cons: My main complaint is that the firmware/ web administration is kind of simple. You cannot set up separate "shares" there is only one. Not much to administer here. But that's not a real fault of the Cloudstor, since it is targeted at users who want to put media out in the cloud. I just wanted a more flexible, configurable NAS.

Also, small complaint is that the power saving feature can't set up a schedule. With the NAS client software starting up the NAS at PC boot up, Windows backup starts up too fast for the drive to be ready on the network and fails. Thus I am usually starting the backup manually after the drive is on the network.

Other Thoughts: I'm happy with the transfer speed, just wish it was more configurable.
