En cuanto a sus aplicaciones complementarias, la única que he probado de momento es Photo Station que es totalmente inoperante cuando se trata de manejar cantidades importantes de fotografías de tamaño mediano-alto. Es incapaz de efectuar el indexado y la creación de miniaturas.

* migration of my backups and media library (from Readynas NV+), about 460 GB
* watched a movie
* played music on the Squeezebox Touch
* a remote backup of another Synology Diskstation over the Internet, 45GB
* hourly time machine backups (continuing on the sparsebundle from the NV+
* download of 4GB BitTorrent.
Even with the disks that busy, the fan sometimes turns completely off. The CPU temperature is consistently at 64 degrees Celsius and the 2 disks are at 42 degrees. My take on the temperature discussion is that these are the temperatures that both hard drives and CPU are designed for and running at these temperatures allows for a super quiet NAS.
This has less than half of the footprint and less than a quarter of the volume of the NV+. It looks quite futuristic, too. Works perfectly with currently 2 Western Digital 1 TB Scorpio Blue SATA 5200 RPM 8 MB Cache Bulk/OEM Notebook Hard Drive WD10TPVT. Much faster response than the NV+ when e.g. opening a folder, accessing the admin interface or picking and starting a song on the squeezebox.
I have only good things to say about it.
Likely not related to the DS411slim, but nevertheless important for those who migrate from another NAS: Make sure you verify that the data is there after you copied it. I noticed skipping on a certain song that went away when I recopied the song from its original location. Upon comparing my old NAS with the DS411slim, many instances of corrupted data were discovered. I am using beyond compare, and compared a whole night long until I figured out that I did it wrong and didn't discover any inconsistencies. Now that I'm doing it right, many corrupted files have been discovered, and I fortunately could recopy them before reformatting and selling my old NAS. Look up file comparison in Wikipedia for a list of tools you can use. Probably there are safer mechanisms than I used to migrate the data in the first place, but this is definitely something to watch out for.
Still looking good. Noticed that a 1 volume set-up using all available disk space cannot be changed later without reformatting. If you add a drive, it will extend the existing volume, it won't allow you to add a new volume on the additional space. For older Apple OS' Time Machine works better under iSCSI and iSCSI is faster on its own partition:
The DS411 has been used nonstop with a lot of downloading video, backing up another NAS remotely, playing music on the Squeezebox and time machine backup for 2 MacBooks. Not a hitch. Once a bit of dust got caught in the fan making a little noise, pulled it out, that's it. As much pleasure with this unit as on the first day. None of the concerns voiced by other reviewers have materialized.
Still not a single problem. The DSM software has been getting continuously better and all updates went through easily. Even though the station is on nonstop, none of the hard drives have ever failed and the S.M.A.R.T. status for all is normal. Today I just added Amazon Glacier backup for the family photos. While it takes a little bit of frowning, I'd say they make it as easy as possible: create an AWS account, add payment option, then enter the AWS key and secret key in the NAS, choose which folders to back up, that's all. You don't even need to create a vault on the Amazon end, the DS does that automatically.
With the model now 2.5 years old it I was hoping for a successor that I can recommend to friends who want to buy a NAS now - but it seems there is still none in sight. Maybe DS411slim is still going too strong for them to worry about that - at least it seems there aren't many comparable devices out there, and the price hasn't changed in 2.5 years!
After 3 years, the first drive broke down. Replaced it and the volume rebuilt without a problem. Chromecast playing videos from NAS, too.
That said, this little guy is perfect for SSDs. Fill it with important photos and documents, recent downloads, security camera footage, a few virtual machines for your VMware cluster, etc. Add on some obscure servers like e-mail, web, VoIP and some cloud-based backups and you'll be good to go for a full-featured system-in-a-box.
The default fan setting is VERY conservative. The DS409slim does not have this issue since it runs the fan all the time. The DS411slim turns the fan off most of the time. I simply set the fan operating mode to "Cool Mode" under "Power" in the Control Panel. The fan is completely silent, yet the temp dropped from 130F to 105F in a few minutes. Power usage went up a scant .4W using some rough measurements.
Still 4 stars for now, but I am currently breaking away from Synology. Some of the unresolved quirks have started to weigh on me. See my review on the DS409slim for more details.
My primary ask from the device was a robust cloud storage to store my photos, music and documents with adequate backup.
Packaging and Dimenstions : I would rate it at 5 on 5.
The packaging was very intuitive and sleek. The product itself was much smaller than I had anticipated for a 4 bay NAS and can be stowed away in a small enclosure (provided there is enough air circulation as it does get quite warm during operation)
Setup and configuration: I would rate it at 3.5 on 5
It takes an intermediate level of understanding of networks and associated interfaces (routers and modems) to setup. The device fits 4 2.5Inch HDD. I bought 2 WD Blue 1 TB SATA II HDD and it was very easy to install it. Adequate screws were provided and even though the bay trays are plastic they are well made and quite sturdy. Watch for excessive vibrations after installation. This indicates that the HDDs are not sitting tight in the trays and can damage the HDD.
I used their SHR configuration which offers the same resilience as RAID configuration and allows for more flexibility for growth. I have a total of 2 TB in a single volume and plan to expand as soon as I can afford more HDD. The only draw back is that the options for HDD in 2.5 Inch form factor is quite limited and is pricey for Solid State HDDs.
After installing the DSM software (Note: the DSM software sits on the same HDD and hence the device is more susceptible to catastrophic failure) I went about configuring the DDNS service. Synology offers Dynamic DDNS service for those without static ip address. The only setback is that even though they claim that SSL certificates can be obtained via StartSSL for free, its not the case as the parent domain Synology.me is a blacklisted domain. Also, to get a cert issued you need to have complete ownership over the parent domain. So your browser will keep alerting you about the lack of a trusted certificate. However, you can invest in a trusted certificate (personally I feel that it's a rip-off to spend $70+ on hosting services).
Configuration: 4 on 5
Setting up users and groups is easy but understanding which permissions precede which like running through a maze. For e.g. I have setup read only access on a folder for a user and read+write on the same folder for the group. While the user permissions trumps the group permissions I found that "Admin" user is also by default (irrevocably) member of users group and removing access to any folder will remove it from Admin user too!! I'm still learning!
My Wi-Fi router was on the supported list and hence I assumed that the ports that were configured from DSM would be available but they were available only for a few hours at best and would lose their configuration. Upon inspection on the router config page, I found that it was being configured as PPPoE ports with a 4 hour lease. I had to manually forward all the ports and since then they have been working as expected.
DSM Software: 4.5 on 5
Photo Station - Easy to use. Again confusion with access permissions. But it will allow you to setup photo station only accounts. Creating thumbnails takes way too long but the end result is extremely satisfying.
Cloud Station - Easy to setup and use. Works very well
Music and Video Station - Easy to setup and works as a DLNA server as well. Immediately found by my XBox 360.
Device was running a little hot and I had to switch it from silent mode to cool mode.
All-in-all a great product.I'm very satisfied with it's performance.
