Not checking was done by services such as a personal cloud and similar ones. Yuzal is only intended to be used as a filesharing server, backup server, torrent server, and media server. In general, I believe that for less than 8,000 dollars, an outstanding device. Plex is unable to install, unfortunately :( The firmware does not experience any lag and continues to function normally. With its benefits including: a simple process for setting it up - intelligent firmware, with the capability to access through the browser; - wide opportunities for distributing rights to users on file server folders (groups of rights); - all files are available on the grid from ANY devices (iphone, win book, apple tv); - There is a time capsule on board - There is a streaming content broadcast server for Apple devices and other devices - A torrent client that does not hang (there were twenty torrents in the queue, and everything was fine). - Disks wake up after waiting anywhere from 5 to 10 seconds, depending on the settings you choose for their standby mode. The client devices do not disconnect; the disk write speed reaches over 40 megabytes per second. Super. Reading even faster. During the process of initializing disks, I was able to correct layout errors and create a new partition table on my own. * - The device has been in continuous use for the past two years without any breaks on my part. There is not even a single imperfection on the disks. How it has consistently worked and continues to do so. I was able to pinpoint the point at which the device's performance begins to degrade: when you have more than seventy torrents waiting in the queue, actively download from it using one computer connected to a gigabit network, and write from another device. The tension begins to ease off a little bit. But not critical. I had to hang up the phone a few times because they were watching the same movie on different devices and trying to delete it from one of the other devices while we were talking. I did not notice any further instances of lagging or hanging. - a new firmware update has been made available, everything is in working order. Improved in intelligence. For synology experts, reaching up to the zuksel, which is analogous to traveling from the earth to the moon, is an unreachable level. - This NAS could not possibly be made any better for you even if God himself tried:) Its cons: - noisy at work. A fan that is active is not something that should be placed in the living room. If you choose to install it, do it somewhere other than where you sleep. - It has been many centuries since there have been any applications for managing storage space from a mobile device. They do their work in a crooked manner. - The Ext file system, if the station is successful, will make it difficult to work with such a disk on Windows without performing additional dances accompanied by a tambourine.
