I will not dwell on the language part, I used to do everything in English so I do not even tested the French.
This NAS has limited power. At home he 85-90Mo bed / s and writes 40-45Mo / s. This is far from saturating the gigabit interfaces that have no other purpose than to be able to have a backup system or a dedicated interface to the Internet or to connect two NAS them. If you are 100mbit expect law-performance 12MB / s read / write and 24MB / s with both interfaces in load balancing.
The interface is clean and uncluttered. A little too bare in places. We would like to have an option of standby when idle disks, a firewall or even more customization options for monitoring, alerts, and antivirus that are really reduced to a minimum.
My version is loaded with 4 * NAS Seagate 4TB HDD (ST4000VN000). The first launch requires a check of RAID which takes between 48H and 72H at home (unless there giga, it takes less time and can be used while working NAS). The racks are effective and appear solid.
The NAS is 3m bed, and does not prevent me from sleeping, attention any time the power light which can be annoying for some (LED discs are hardly visible and the screen goes to sleep after a moment).
You have a full Linux (debian) sour the system (be careful so this is not the ARM all available applications, gaps include Dropbox, the version provided by Netgear only to send to Dropbox and not recovered ).
I also regret their management by sharing and not by folder. I would like to put rights or save some files without separating the form of shares.
The single-core processor and 512MB RAM also limit certain uses (Crashplan is not installable for example, and transcoding with plex is to forget).
Level applications include classical, bittorrent client, RSS reader, various CMS and other web interface software (Joomla, Drupal, Moodle, OpenERP, orange HRM ...), one or two multimedia device with DLNA servers, some application data storage (Barracuda drive, owncloud ...). So nothing transcendent but the minimum is.
In short it was a basic NAS with 4 disc slots (which is rare enough to emphasize) for a pretty decent price. Nevertheless OS Synology is better finished. Netgear is still trying to smooth things over with the BTRFS. There is a demo version online to test the OS and VM Synology virtualbox to test the OS ReadyNAS.
For information support is via chat or telephone for 3 months and then by email. The various representatives that I had were quick to answer (except for message Christmas period) and friendly. As against the instability problem I had was not their responsibility but that of the developers who took a little time to solve it.
If you want to share files this is acceptable, by cons if you want to make a mini-server go your way.
