Great Drive With Periods Of Frustration

Reviewed in the United States on May 7, 2017

Size: 16TBVerified Purchase

This is a nice piece of electronics that is easy to setup and use. Many RAID modes available including JBOD (Just a bunch of drives) for the most storage space. On setup everything worked and it was easy to access from most anywhere. Then the problems started. The drive periodically disappears from my Network. Many people have mentioned this problem and there are lots of fixes listed. First I turned off Sleep mode thinking that somehow was contributing to the problem. I also gave the drive a Static IP. No matter what settings I tweaked the drive still disappears from my Network about 3 times a week. I have not found a fix that can get it back online other than unplugging the power supply and letting it refresh itself. When I do this the drive is back online in about 5 minutes and remains online until it decides to run away and hide again. I'm kind of disappointed in Western Digital as they are a good company that usually addresses these kind of problems. Since I owned this drive I have gotten 3 or 4 firmware updates from WD. Each time I hope that they have finally found and fixed the problem but this has not yet happened. for the High Price WD expects for this drive I believe they should have fixed this long ago. I don't know if any of the other big drives like this from other companies work any better. This drive was all that I wanted and needed for my system but if I had it to do over I would have bought a smaller setup that from the reviews I have read seem more stable. (I have a WD Cloud drive in 4tb that has been rock solid for many years.) I wish that WD would make this much more expensive drive work as well - but it doesn't!

Nifty little prosumer NAS (4-bay)

Reviewed in the United States on November 3, 2017

Size: DisklessVerified Purchase

This review is for the WD EX4100 (4-bay), as Amazon has decided to merge reviews for the 2-bay and 4-bay.

Edit: After 6 months of use, I have the following information to add:
1. The "drive failure" notice appears for drives without disks inserted. This can be mitigated somewhat by scheduling periodic downtime.
2. The write speed is (obviously) still limited by the HDD you use and your network connection.
3. WD documentation is still less than stellar and they still over-rely on group support boards.
4. To enable dual-bonding on the gigabit ports, enable 802.3ad.
5. You should not be utilizing older/personal drives. The WD RED 5400 RPM drive is likely going to be your best choice for the drive due to stability/longevity compared to the 7200 RPM version - unless of course you choose to go with the WD Black instead.
6. Again, the "EX" in the "EX4" stands for "Expert". It is supposed to be an indicator for those less technically-inclined that this is a bit more than a "plug-and-play" solution.

Original Review:
First and foremost: This device is not as straightforward as some other types of devices designed towards the home user. You will need to dedicate time and brainpower to setup and management of any Enterprise Solution that you buy (hence the product featuring the use of EX for Expert). If you like everything to work without you doing anything more than pushing the "next" button on an install wizard, this is not for you.

I decided to purchase this Network Attached Storage after running a spare PC as a media server for a while. I purchased a WD Red 8TB drive separate as it was cheaper than the bundled version of the EX4100 with 2 4TB drives. The max storage handling for this solution is 32TB, or 4 8TB drives. I decided to run JBOD for the time being, with a separate backup for critical files.

Included in the box is a setup guide that is effective for about 15 seconds. The expectation is that you (the person setting it up) will navigate to WD's website to access proper setup guides. As far as the actual setup, it's not too complicated: Insert drives; power on (takes a minute to initialize); access control interface via a computer on the local network; configure RAID (even if JBOD); format drives; setup "shares" for file storage; and access the shares via network discovery on your computer.

One issue that I had was a ticking sound from the hard drive every 5 seconds. According to WD's website, this is normal for their enterprise drives in standby mode. Their drives are rather noisy (although most Enterprise systems are, to be fair;) and this may impact where you wish to place the device.

You will need to wire it in to your router (assuming you are using a home router/switch/WAP combo). A CAT-5 cable ("Network" or "Ethernet" Cable sold in stores) can support 10Mbps transfer easily, but 100Mbps is not so likely if the cable is longer than a certain distance (or if you forget to account for TCP overhead). With the cable I am using, I see ~90Mbps transfer. This translates to ~11MBps, which is important to consider as files are measured in Bytes, not bits (8 bits a Byte; a 700MB file is 5,600Mb). There is an included Gigabit cable, although it is (by necessity) ~3 feet long. This calculates to 125MBps, but one needs to still consider all other legs of transport for speed. For a car analogy: A Bugatti Veyron will not be able to travel at 200mi/h while in gridlocked traffic.

If you have a lot of files that you plan on transferring from an external device (such as a portable HDD) onto the NAS, I recommend connecting the device to the USB drive on the front of the NAS. Next, you should navigate to the control panel via your computer. Use the "backup" function to have the NAS copy files from relevant folders within the external device into the location on the NAS that you want them to reside. This way, you don't have to utilize your network nor computer to have the files copy. The "backup" function is also a way to setup an automatic backup of critical files to another location, should you choose to utilize this function. For regular use where you are copying small files a few at a time, use of the fileshare (via Network Discovery on your computer) works well.

My biggest concern with the device is actually with it's control interface. The default interface is port 80, and does not support port 443 (HTTPS) connections. This includes the login function and device administration. You can enable SSH once you have setup the device; but that doesn't change the aforementioned issue. The interface will also allow you to attempt to do things that could be predicted to fail, such as trying to install Plex Media Server if you have no drives configured (hangs at 98%). The page does have a timeout function, which is nice. Still, I would not recommend this device for a true Enterprise solution.

For Plex users: This device does decently with direct stream. If your files are .mp4 (the MP4 container) or .mkv and using H264 (video playback) or H265 (HVEC) and AAC, MP3, or FLAC for audio, you should be able to play the file well. .avi (AVI container) is not supported by the Plex client (as it costs money for the license), nor is DTS passthrough, so the Media Server will try to transcode it. The EX4100 is not powerful enough to transcode, so you cannot play such files if using this device as the server. You can use a more powerful device (such as your computer) as the server, and host the files on the NAS; or use a tool such as Handbrake to convert the files to a direct play format.

Overall, I like the product. I think it does a decent job at balancing Enterprise capabilities with home-use requirements. The cost of the device, initial setup requirements, lackluster in-box documentation, and lack of standard network security protocols are the biggest issues that I see with this device.

This review will save you money and headache and fraustration

Reviewed in the United States on July 16, 2017

Size: DisklessVerified Purchase

This is a really good product but only on PAPER. Following is the biggest issue that I have with this product that will literary makes it useless.

First off, a quick background on me, Im a network engineer and my job is to manage and configure networking products on daily basis. With that said, this SAN is not stable when it is onna network. This means that for the first couple of days, you can connect to the dashboard from your network and remotely, but after that it goes missing from every point of connection, meaning you cannot connect to the unit or the dashboard regardless of what you do. The worst part about this is that all the information on the little blue screen located on the unit shows everything is working fine. There is a physical power button in front of the unit but it does not do anything regardless of how long you hold it. It is as if the unit just hangs and freezes. The only way to reset the unit is to disconnect the power cable which is really the last thing I want to do with products that have spinning disks in them. My mistake was not returning this in time and thinking that I can fix it. For those of you having this issue or thinking about buying it, all the solutions that are on the forums online, such as setting static ip and doing system restore, WILL NOT fix this issue. I called WD support and instead of trying to trouble shoot the problem, they are just going to RMA it. What really pissed me off was that, they told me that they are going to pay for the shipping this one time as curtesy. So basically, your product is faulty and I have to pay for it to get shipped back?!!! this is just absurd. Please save your money and DO NOT buy this junk.

------------------------------------------------------------------------------------------------------------------------
Update 8/8
I have now called WD about 8 times to get one simple pre-paid shipping label for their defective product. This is 2017 and WD is unable to provide a simple shipping label because "their servers are down". Apparently it takes them more than a week to fix their servers. This is one of the worst companies I have ever dealt with specially when it comes to customer service. Please save your money and time and stay away from them. I wish I could give them 0 stars.

This NAS will continually lose network connections and become unavailable.

Reviewed in Canada on March 5, 2019

Size: DisklessVerified Purchase

Please do a search on the web for this units known network problems. Many users have suffered this fate. Even Firmware updates have failed to resolved this. Power button will stop working and not shutdown the unit. Only pulling the power cord will do. Unit regains connections upon startup, but will disconnect in a few days.

Falla intermitentemente y soporte técnico aun no tiene solución

Reviewed in Mexico on February 13, 2019

Size: 24TBVerified Purchase

Después de unos meses de uso y pruebas, considero que es un producto con varias fallas, intermitentemente se desconecta de la red, se queda congelado y no es posible apagarlo desde el botón de inicio ni desde el pase del control web, sólo desconectándolo completamente desde la corriente. Hay inumerables quejas al respecto en el sitio de Western Digital desde hace un año y ninguna respuesta de soporte, por lo que se entiende que No han podido resolverlo. Estoy esperando respuesta de Western Digital,. Una vez que la reciba actualizaré esta reseña, por lo pronto no recomiendo adquirir este producto.

A NAS worth considering!

Reviewed in Canada on May 11, 2016

Size: 8TBVerified Purchase

Feb.14.17 - Update

I've been using this NAS for 10 months now and it has been a solid performer. Transfer speeds are very fast if you use a good router and cat 6 or 7 cables. I bought a few cat7 cables from a vendor here on Amazon and noticed an improvement in speed from my cat5 cables. Spending the few extra dollars was worth it to me. The only weak point I have about this NAS is that you cannot expand the memory, so if you plan on buying a NAS to use as a media-server, you might want to consider a device with more memory and/or one that allows you to add additional memory. I have Plex installed on this NAS and have used it and, for the most part, it works fine. I have noticed that it has difficulty (at times) maintaining picture quality - as in you get a spinning wheel and have to wait a moment. There is a possibility the problem is/was associated with my Chrome Cast device and the NAS wasn't to blame. However, because I have Plex installed on another PC (also used as a media server) and haven't experienced the same problem casting from it, I suspect the problem is associated with the NAS being a little under-powered for some intense jobs.

I am still very happy with this NAS and would not have a problem recommending it to friends.

End review update
----------------------------

I did a lot of research before finally deciding to purchase this device and, after having used it for a few days, I am very satisfied with my purchase. This is an 8 TB unit with 2*4TB drives, which means two drive bays are empty. That might be a sore point for some people, but it was the exact configuration I wanted because it allowed me to install 2 additional drives to increase the storage capacity. The primary purpose of this NAS is to provide a backup location for the Apple & Window computers I have. I therefore did not use a RAID configuration - JBOD only.

Installation and setup was very easy and straight forward; simple enough for a novice to accomplish without too much trouble and/or spending a lot of time trying to do it and getting frustrated. Now, having said that, I was not initially pleased with the read/write speed during initial testing. It was so slow that transferring a large file would have taken hours, not minutes as would be expected on a Gigabit network. I knew it wasn't a (NAS) hardware problem and, after reviewing the configuration, I knew if must be something to do with my network - how I connected the NAS to the network. The problem was resolved by changing the network cable(s) and the switch/router. Now the transfer rate is fast, very fast!

Software: I've read some reviews where people complain about the interface and/or functionality. Is it the best? Probably not! Is it easy to set up and use, and does it do the job? Definitely! One important criteria for me was the ability to use Apple's TimeMachine without having to jump through hoops. All I can say it that it works right out of the box - period! There is also software to do real-time backup of specified folders, for example your Documents, and you can define the number of versions to retain. I have not implemented this yet, but may in the future. If you are familiar with a product called Genie Timeline, then you should be happy with this functionality.

I would definitely recommend the WD My Cloud to anyone looking for a NAS that provides a reliable storage solution with room for growth at a reasonable price.

Buena inversión para multimedia local

Reviewed in Mexico on September 18, 2018

Size: DisklessVerified Purchase

Tengo una librería de varios terabytes de videos, musica e imagenes. La funcionalidad es buena y tiene varias apps para ver el contenido. Mi preferida es Plex (puede costar extra), esto para tener estos contenidos en cualquier dispositivo que soporte la app de Plex (tablets, telefonos, Fire Stick, Chromecast, SmartTV, etc.)

La unica desventaja es la necesidad de tener un disco duro ya formateado ya que cualquier instalacion nueva el sistema te pide darle formato. Yo esperaria que reconozca directamente un disco formateado con NTFS para solo meter y reconocer. Tuve que vaciar un disco a otro, formatear el primero y luego regresar los archivos una vez ya montado el disco en la NAS. Pequeño inconveniente pero nada que no se puede resolver.

Una vez instalado es practicamente silencioso y con una luz azul tenue que no molesta en una sala de estar.

Je suis un peu déçu de mon achat car je pensais que j'allais avoir un 16T à combler. Mais une fois configuré, il y a seulement 11T de libre pour enregistrer tes trucs. J'ai appelé WD Support pour leurs demander si c'est normal et leurs réponse fut positive. Le 6T manquant est utilisé pour des sauvegardes en cas de problématique. Donc je peux seulement utiliser 75% du 16T. Par contre, c'est assez simple pour compléter la configuration quand le lien indiqué dans le manuel d'installation fonctionne. Voilà, il n'y a que 11T au lieu de 16T. :-(
