Missing details of instruction for this important device. Everything is on the WD website. I called the tech support two times and spent many hours. My network could not recognize the device. I returned it and repurchased another one. It took a week to receive the new one. After I received it and found out I am not able to use it because the plug is for Europ.
I give up!!!!

5.0 out of 5 stars Works brilliantly once set up!
Reviewed in the United Kingdom on March 6, 2024
Verified Purchase
Had this for only half a day so will update this as I go on if anything changes my opinion. So where to start well set up is easy when it comes to assembly (I bought diskless version) disk are easily insert into the very compact double drive bay. The whole thing is silent when in use though during boot up when it tests the fans etc it does get a bit louder but only briefly. On the software side I only had an issue setting up the Plex media server app but that resolved itself after a few attempts not sure what the issue was but I digress. I installed all the apps I wanted at the click of a button and configuration was painless. I strongly urge the use of the virus protection app and you set up an automatic scan schedule as it only takes a minute and protects you if you intend to use remote access as I have. I can't say I had any issues that another reviewer encountered as I am not that computer lierate but have spotted a lot they doing wrong and avoided the same obvious mistakes. All in all I have found to be fast and quiet and solidly built with some well chosen apps made available for installation on it. I have only tested the official supported apps but it does seem other open source ones are available but I urge you to use caution and only get from trusted sites if you want to add any of them as this is a reasonably expensive bit of kit to risk turning into a brick! All in all great to use very easy to set up and personalised and streamed all my test media copied to it to my TV my laptop and my phone both locally and over the internet would definitely recommend this to anyone wanting control over their data. The only thing I haven't managed to get it to stream with yet is my Google nest hub and Google home speaker group but I hope to have that sorted soon after a look online for more up to date method of doing so as it seems it is to do with Google changing things their end that is the issue preventing me from doing that and not a fault at WD's end.

Il dispositivo è facile da configurare. I dischi si inseriscono facilmente e le etichette in dotazione per i 2 dischi permettono di non confonderli una volta installati, se rimossi per manutenzione, pulizia, sostituzione etc. Dispone di una ventola di raffreddamento che non è proprio silenziosa, ma nulla di fastidioso.
Il software è fatto molto bene e viene aggiornato costantemente. Permette di creare utenti e assegnare ad ogni utente i permessi per ogni cartella presente sul cloud. La app su ios e android permette backup automatico e potete dimenticare i costosi cloud.

È un mini server alla fine. Lo si collega alla rete di casa via cavo, dopodiché lo lasciate lì. Create un account e a quel punto potrete accedervi da qualunque dispositivo. PC, tablet, smartphone (non vi si può accedere via cavo). Chiaramente ci vanno due hd, io ne ho presi 2 da 2t facendo in modo che ciò che salvo venga copiato su entrambi in modo che se si brucia uno, c'è l'altro. Facendo così ho comunque 2t in totale.
L' EX2 ultra si configura subito ed è veloce, quando vado fuori per viaggi lo lascio acceso così posso connettermi anche da dove mi trovo e mi è capitato di usarlo come piattaforma streaming accedendo ai video. Consiglio di lasciarlo acceso sempre e al limite possono essere impostati gli orari di standby e lo fa in automatico.
Unica pecca (ecco perché 4 stelle) è che non ha un tasto di on/off e bisogna togliere la presa di corrente Oppure spegnerlo dall' app però per riaccenderlo va tolta e rimessa la presa, cosa un po' antipatica. Però c'è l'ho da quasi due anni e funziona perfettamente. Consiglio

4.0 out of 5 stars Perfecto para mi uso: almacenar / reproducir contenido digital (OJO: leer reseña)
Reviewed in Spain on December 21, 2020
Verified Purchase
Tenía muchas dudas de comprarlo, tras leer muchísimas de las críticas negativas que ha recibido este producto: velocidad lenta de transferencia de archivos (tanto lectura como escritura), parones o tirones en reproducción de vídeos, cuelgues del panel de administración del equipo, etc.
Intentaré ser lo más detallado posible en mi reseña, para que aquellas personas que estén en duda de su compra y le quieran dar un uso similar al mío y con unos equipos (PC, router, etc.) similares en características, puedan hacerse una idea de las capacidades de este dispositivo.

Producto:
En mi caso compré una unidad sin discos reacondicionada (Amazon Warehouse) en la semana del Black Friday (había un 30% en productos reacondicionados). Tanto el embalaje, como el producto y sus accesorios, estaban en perfecto estado. No parecía ser un producto reacondicionado.

Instalación:
Puse 2 discos duros WD Green de 2TB cada uno (5400 rpm), en modo JBOD (se gestiona cada disco duro de forma independiente). La versión del SO del panel de administración del equipo era "My Cloud OS 3, firmware 2.3x" y actualicé el firmware a la versión 2.4x. El panel de administración te indica que hay una nueva versión disponible del SO, My Cloud OS 5, pero tras leer muchos post del foro de WD, en la que se describen numerosos problemas en el proceso de actualización a la versión 5 del SO, decidí no actualizar y quedarme en la versión 3 del SO. A día de hoy 21-12-2020, parece que mediante nuevos firmwares que van sacando de la versión 5 del SO, se van solventando ciertos problemas, pero de momento, seguiré en la versión 3.
Después de configurar los 2 discos en modo JBOD (como he descrito antes), asigné una dirección IP fija al equipo y desactivé todos los servicios de la nube de WD, ya que no lo voy a utilizar desde fuera de casa y el acceso desde un teléfono móvil o tableta, a las carpetas de ambos discos duros, lo realizo desde el administrador de archivos de ambos dispositivos y no desde la aplicación "My Clouyd OS 3", para Android en mi caso (el uso de esta aplicación, te obliga a activar los Servicios de la Nube de WD, con el consiguiente incremento de recursos).
Tras estos pasos, creé una serie de carpetas en ambos discos duros y las protegí mediante usuario y contraseña.

Topología de red y equipos:
Switch Gigabit TP-LINK de 8 puertos. A este switch están conectados:
- router Asus RT-AC68U (cable Ethernet categoría 5e).
- intel NUC5i3RYH (CPU i3-5010u, 12GB RAM DDR3 1600MHz y SSD Crucial BX500 de 240GB), mediante cable Ethernet categoría 6.
Sistema operativo Linux Mint 19.3 (64 bits), con sevidores de medios Emby y Plex.
- TV LG OLED55C7V, mediante cable Ethernet categoría 5e. Clientes de medios Emby y Plex.
- PC Sobremesa (CPU i5-4460, 8GB RAM DDR3 1600MHz y SSD Samsung 850 EVO de 250GB), mediante cable Ethernet categoría 6.
Sistema operativo Windows 10PRO, con actualización de Octubre 2020.

Previamente, el PC intel NUC tenía conectado uno de los discos duros de 2TB instalado en la unidad WD, a través de una caja externa YOTTAMASTER USB3.0.
La velocidad de descarga mediante cliente Torrent, rondaba picos entre 50-60MBytes y medias de 35-45MBytes (tengo 600Mbits simétricos, lo que en teoría son 75MBytes).
La velocidad de descarga de forma directa, rondaba entre 60-65MBytes.
La velocidad de transferencia de archivos (ficheros de hasta 89GB) entre el PC de sobremesa y el intel NUC (de forma bidireccional) rondaba los 110-113MBytes,
de manera sostenida.

Transferencia/descarga de archivos. Escenario de pruebas 1:
Unidad WD conectada mediante el cable Ethernet que viene en la caja (creo que es categoría 5e) al Switch Gigabit TP-LINK de 8 puertos.
- Prueba de mover 1 archivo de 60GB desde PC de Sobremesa (W10PRO) a una carpeta de la unidad WD: velocidad de transferencia entre 25-35MBytes.
- Prueba de mover 1 archivo de 60GB desde PC intel NUC (LM 19.3) a una carpeta de la unidad WD: velocidad de transferencia entre 25-30MBytes.
- Prueba de mover 1 archivo de 2GB desde PC de Sobremesa (W10PRO) a una carpeta de la unidad WD: velocidad de transferencia entre 50-60MBytes.
- Prueba de mover 1 archivo de 2GB desde PC intel NUC (LM 19.3) a una carpeta de la unidad WD: velocidad de transferencia entre 40-55MBytes.
- Descarga de ISO torrent desde PC de Sobremesa (W10PRO) a una carpeta de la unidad WD: velocidad de descarga 10-20MBytes.
- Descarga de ISO torrent desde PC intel NUC (LM 19.3) a una carpeta de la unidad WD: velocidad de descarga 25-30MBytes.

Transferencia/descarga de archivos. Escenario de pruebas 2:
Unidad WD conectada mediante el cable Ethernet que viene en la caja al router Asus RT-AC68U.
Realizo las mismas pruebas que las descritas en el Escenario 1, obteniendo resultados similares en cuanto a las velocidades de transferencia/descarga.

Ante estos resultados, lo primero que pensé era que las reseñas críticas estaban en lo cierto, ya que la unidad no mostraba ningún tipo de fallo.
Decidí investigar un poco y en uno de los post del foro de WD, se mencionada que una de las causas de la lentitud en las velocidades de descarga y/o transferencia de archivos, puede ser la gestión de las carpetas mediante la creación de usuarios y contraseñas.
Así que eliminé el acceso a las carpetas mediante usuario/contraseña, volví a conectar la unidad WD al Switch TP-LINK y realicé las mismas pruebas que las descritas en el Escenario 1:
- Prueba de mover 1 archivo de 60GB desde PC de Sobremesa (W10PRO) a una carpeta de la unidad WD: velocidad de transferencia entre 110-115MBytes.
- Prueba de mover 1 archivo de 60GB desde PC intel NUC (LM 19.3) a una carpeta de la unidad WD: velocidad de transferencia entre 50-60MBytes.
- Prueba de mover 1 archivo de 2GB desde PC de Sobremesa (W10PRO) a una carpeta de la unidad WD: velocidad de transferencia entre 113-119MBytes.
- Prueba de mover 1 archivo de 2GB desde PC intel NUC (LM 19.3) a una carpeta de la unidad WD: velocidad de transferencia entre 60-70MBytes.
- Descarga de ISO torrent desde PC de Sobremesa (W10PRO) a una carpeta de la unidad WD: velocidad de descarga media de 30-35MBytes con picos de 50-60MBytes.
- Descarga de ISO torrent desde PC intel NUC (LM 19.3) a una carpeta de la unidad WD: velocidad de descarga media de 20-25Mbytes con picos de 35-40MBytes.

Efectivamente, la gestión de carpetas mediante usuario/contraseña, afecta y mucho a las velocidades de descarga y/o transferencia de archivos. Y como se puede observar, el uso de un sistema operativo u otro, también. La verdad es que de Linux no entiendo mucho, pero me puse a buscar por foros de Linux Mint y llegué a la conclusión de que al igual que la unidad de WD "capa" las velocidades en carpetas con usuario/contraseña, Linux Mint (en mi caso) hace algo similiar con carpetas que estén en dispositivos de almacenamiento en red (ya que como mencioné anteriormente, uno de los discos duros lo tenía en una caja externa y las velocidades eran similares a las del PC con W10PRO). Incluso asignando permisos root a esas carpetas, no logré que las velocidades aumentasen.

Como última prueba de descarga de torrent, instalé desde la pequeña tienda de aplicaciones, la aplicación de Transmission. En este caso, las velocidades de descarga eran de media 8-10MBytes, con picos de 12-15Mbytes. Creo que en este caso, el procesador Marvell Armada de la unidad WD, no puede con las numerosas conexiones que se producen para un torrent y se satura.

Transferencia de archivos entre Samsung Galaxy Note 8 y carpeta compartida en unidad WD.
Conectándome con el móvil a la red WiFi 5G de mi router Asus y estando éste a unos 5 metros del móvil, la velocidad de enlace es de 650-700Mps.
Pruebo a transferir 1 archivo de 2GB de forma bidireccional y la velocidad es de 25-30MBytes.
Pruebo a transferir 20 fotografías de unos 8-10MB cada una de forma bidireccional y la velocidad es de 10-15Mbytes.

Reproducción de contenido multimedia 4K. Escenario de pruebas 1:
Unidad WD conectada mediante el cable Ethernet que viene en la caja al Switch Gigabit TP-LINK de 8 puertos.
Vídeo .mkv de 75GB de tamaño y bitrate 83Mbps.

- Servidor Emby instalado en PC intel NUC5i3RYH.
- Cliente Emby instalado en TV LG OLED55C7V. Cliente configurado para reproducción directa: es el TV quién realiza la transcodificación y no la unidad WD.
El video comienza a reproducirse bien, pero a los 10-15 segundos comienza a dar tirones de 1-2 segundos, que se repiten a lo largo de la reproducción.

Este mismo video .mkv, reproducido desde el disco duro cuando lo tenía montado en la caja externa y conectado por USB al PC intel NUC, no realizaba ningún tipo de parón o buffering. La reproducción era totalmente fluida.

Reproducción de contenido multimedia 4K. Escenario de pruebas 2:
Unidad WD conectada mediante el cable Ethernet que viene en la caja (creo que es categoría 5e) al Switch Gigabit TP-LINK de 8 puertos.
Vídeo .mkv de 75GB de tamaño y bitrate 83Mbps.

- Servidor Plex instalado en PC intel NUC5i3RYH.
- Cliente Plex instalado en TV LG OLED55C7V. Cliente configurado para reproducción directa: es el TV quién realiza la transcodificación y no la unidad WD.
Reproducción perfecta, sin ningún tipo de tirón, parón o buffering.

Reproducción de contenido multimedá 4K. Escenario de pruebas 3:
Unidad WD conectada mediante el cable Ethernet que viene en la caja (creo que es categoría 5e) al Switch Gigabit TP-LINK de 8 puertos.
Vídeo .mkv de 75GB de tamaño y bitrate 83Mbps.

- Servidor Plex instalado en unidad WD. El servidor "Plex Media Server" lo instalé desde la pequeña tienda de aplicaciones que tiene.
- Cliente Plex instalado en TV LG OLED55C7V. Cliente configurado para reproducción directa: es el TV quién realiza la transcodificación y no la unidad WD.
Reproducción perfecta, sin ningún tipo de tirón, parón o buffering.

Como puede observarse, el uso de un cliente u otro, puede afectar a la reproducción de contenido 4K. Aún cuando no las describo aquí, también realicé pruebas de reproducción de vídeos .mkv con resoluciones de 1080p y bitrates entre 50-60Mbps y ni con Emby, ni con PLEX, se produjeron tirones o parones. Las reproducciones
fueron totalmente fluidas.

Como última prueba de reproducción de contenido 4K/1080p, utilicé el protocolo DLNA. La unidad WD tiene un servidor DLNA (Twonky). Desde la TV, mediante la aplicación propia de LG de "Fotos y Video", accedí al vídeo de pruebas (.mkv de 75GB de tamaño y bitrate 83Mbps). Al reproducirlo se produjeron los mismos resultados que cuando lo hice con la aplicación de Emby desde la TV: pequeños tirones de 1-2 segundos, que se repiten a lo largo de la reproducción.

Nivel de ruido: sólo en el caso en el que instalé la aplicación "Plex Media Server" desde la tienda de aplicaciones de WD y tuvo que hacer el primer escaneo de las carpetas con los videos .mkv, para agregarlos a la biblioteca, escuché el ruido de los ventiladores. En el resto de casos/escenarios, los ventiladores no se oyen
(la unidad la tengo a unos 5 metros de distancia).

Espero que con esta reseña, pueda ayudar a todos aquellos que tengan dudas en su compra. Es cierto que por especificaciones y software, no es comparable a otros equipos de gama de entrada de Qnap o Synology. Pero si sólo lo quieres, como en mi caso, para almacenar contenido digital y reproducirlo en un equipo (TV, Tablet, etc.) el cual sea quien realice la transcondificación (y no la unidad WD), es perfectamente válido.

Verified Purchase
Ho acquistato questo NAS, perché ero stanco di dover copiare le foto e i video dalla SD della fotocamera a due differenti dischi per averne un backup garantito. Tra file RAW e video in 4K mi occorrevano ore per salvare il tutto su due dischi.
Questo NAS, insieme a due dischi sarà da 2TB ha tutto quello che mi serve, e anche di più. Ha un'interfaccia grafica eccezionale che consente di configurarlo in tutto da un semplice telefono qualsiasi sulla rete di casa.
Non ho necessità di raggiungerlo dall'esterno, ma se volessi potrei raggiungerlo anche dall'esterno, o attraverso il suo servizio Cloud o eventualmente configurando una VPN o sbloccando alcune porte sul router (per i più smanettoni).
Per il resto ha tutti i servizi per previsti dai vari sistemi operativi che consentono la lettura e scrittura sulla rete di file, come potete vedere anche dallo screenshot dell'interfaccia grafica. Personalmente uso Samba per raggiungere il NAS da dispositivi Windows, FTP per raggiungere il NAS dal telefono (attraverso semplici app gratuite che integrano client FTP), NFS per Linux e AFP per dispositivi Apple.
La configurazione in raid 1 e formattazione dei dischi è un'operazione semplicissima, a prova di inesperto, e garantisce il backup continuo dei file contenuti nei due dischi. È anche presente un servizio che ti avvisa via mail relativamente a failure/avvisi.
Insomma, molto soddisfatto dell'acquisto, spero duri nel tempo.
