large capacity, RAID mirror, many options to configure, supports a lot of applications and uses very slow to copy files to/from the network (even wired). Took almost 48h to copy 600GB of pictures from LAN. Very difficult to set up the right users with correct sharing options. Slow DLNA (TV-Router-WD : all 10G wired), slow VIP if you want to host a server (it starts to lag after 4-5 connections).

External disk's excellent. 9/10 But I bought Cloud (not USB) to be visible from the Internet. Unfortunately I do not have a public IP (otherwise I would have made do with VPN and USB drive into the router), and this should offer connectivity via WDCloudovou service. It is not entirely useless. After several days of persuasion, so I could not join under your account's connection speed via WD servers around 40 kilobytes / s. Additionally, the transfer takes place, so that when copying a file from a cloud drive will upload the file to the server WD, and only after the full upload begins downloaded to the client. When these speeds so few MB file takes too long, without even get a preview image or video until the entire uplodované WS server. So this function I had to turn off the disk and serves as obyč. 20% cheaper USB version. Have public address either on disk or at least a router, so this problem is not. Drive connects to the WD website, and gives him his dynamic address and port and you can establish a direct client connections from anywhere directly to him and be limited only by the speed of the network. Unfortunately, what I watched, or competition in passive mode cloud does not work well, and this is at least as great local disk, so either that, or simply Synology NAS.
large external drive that does not need to each computer over conventional NAS - cost option to place the router somewhere outside the residential zone speed (1Gbit network) quite growls when spin (fan, but closed with a power-saving mode) poor connectivity if no public address (may not be static) or router with a public address and zapnutelným uPnP

SSH and FTP access UPnP Speed ??Disk I'm connected to your home network. So far I did not allow the router to SSH or FTP access from outside, but it may eventually do, yet I managed the client who comes to windows. Ideal for downloading large files option wget straight over ssh without this man pulling on a computer and then copied to disk (via wifi connection is slow, but it is a matter wifi, no disk). Via USB and via a network cable everything goes perfectly fast. So far I have no Nenas.

Super device backs up the notebook, tablet and phone, I can be accessed over the local network or over the Internet. Unfortunately the system often breaks down and it is not possible to access the device until you restart it. It then lacks the charm of access via the Internet (from work, holiday, ...)
easy installation, elegant design support Android and other USB host often falls connection - necessary to restart :(

I use as a backup server to Synology NAS. For these purposes it conforms smoothly. Most of the time the device is asleep.
after minor modification can be used as an rsync server backup easy, intuitive adjustment silent rsync service could be configurable via the web interface

the network HDD to a direct connection to a router, is particularly suitable as a central store for households or smaller companies everywhere where there is a need fast access to data without transmitting and of attachment to an external drive. After attaching a loading Just enter "to join another network drive" and can be used. Although there is also a possibility of transferability and Connecting to a variety of networks, its advantage is particularly its positioning as ever to him, so multiple users can access. High speed is useful only when gigabitovom a networked connection while the rate of registration was in my case (under optimal conditions) and moved up to 45 MB / sec read speed sites up to 90 MB / s. This depends on the type of payload data used hardware, and also from that how many participants are currently connected to disk. Less disappointing is the fact that the built-in USB port is not an alternative to network-sided attachment but merely serves to connect the HDD to another for the purpose of data backup or expansion of capacity. HDD operates reliably over time, and the non-use sleep itself so that there is no need of detaching the socket. For he that seeketh the central store for more computers can I warmly recommend this CD.
A network drive is still available without further In case of attachment to being connected to a different network configures itself to name but remembers the original. Rapid transmission at GLAN connection when idle sleep is alone and there is no need nothing undock. Lets you create complete backups of up to 3 different computers. Configuration options and access. Also allows connection mobilov, tablet and remote access. the rate of enrollment rapidly declines when wifi connection or at 100Mbps network. The USB port is only used for connection to another drive. Remote access without fixed IP addresses is only possible through the WD Web site. It is available only in white designs.

All in one place and access as needed. Does not fill the HD on a PC or tablet. The possibility to grant access rights to folders. Viewing pictures or movies in HD on mobile no problem at all tested on a 3G mobile network visiting friends. I recommend to buy.
Ease of connection, instructions in CZ to download from the official website. It works as I expected. Data access from anywhere as needed. Streaming movies at home on the phone, tablet and other PC without any problems.

It really works, speed of access to the cloud from the outside and from slow networks E OK when accessing the 3G so there is no problem. But you need to set the router port forwarding. Simple control works perfectly on Mac. Handsome look :-) RAID can not for the time being, you must let automatically every day at a certain time to do so. Safepoint, so he leaves the disk where you have a backup of the previous day and lose a day job.
