I recommend, very good product and LDLC at the top as always, conforms to the description. I would make the same choice again.
Delivery a little long (24 days from France to New Caledonia) UPS should improve its services to match the price charged. Perfect packaging, product received without any damage. Easy to install, all that's left to do is transfer the data from the old one to the new one. Delighted with the product.
I use this NAS to store a few holiday movies and hold a virtual machine (win10) to retrieve them from my friends. It does its job perfectly. I never run out of power on the VM. Installation is easy.
The fans can be noisy but are exchangeable if they really bother you. It does kick in from time to time, especially when I'm transferring large files or playing a rather large movie on my APPLE TV. Otherwise it's dead quiet, you can only hear the discs.
The SYNOLOGY interface is rather sleek and guides you in your actions with a lot of advice in the interface.
It is not far from perfection for my case of use. You have to pay the price...
I've been using it for a while now, but it's a great service and I'm very pleased with the service. I've been to the store for a while now and it's been a great experience for me.
RAS. Product well received but not yet tested as I am waiting for the Toshiba N300 10T price drop.
Product purchased to replace a DS1815+ which had just given up the ghost during the holidays and hot weather.
Inserted the disks in the right order, activated the switch, and everything was recovered without having to restore a backup.
What happiness...
This NAS replaces an older model with the same form factor, which had given up the ghost.
The big advantage with Synology is that you move the disks from the old one to the new one and in less than 30 minutes, everything is back up and running.
I would appreciate a little more clarity on availability and delivery from LDLC.
Service ok. Delivery on time.
Availability ok.
Replaced the old ds1812+ NAS that broke down.
Physical change of disks on the new NAS. Everything works and restarts without problems.
Adapted old version to new NAS version without any problem.
I've been using it for a while now and it's a real pleasure to use it as a replacement for a "DS214+".
I'm very pleased with the quality of the product and the service.
I've had it on endurance test 24/7 for over a month now. Everything runs perfectly well, barely noticeable noise level.
I bought this DS1621+ to replace my Linux server which is a bit old.
I'm a bit reluctant at first, so I set up an endurance test plan before transferring my data to it.
I increased the memory to 16GB (with 2 Kingston ValueRAM SO-DIMM 16GB DDR4 2666 MHz CL19 DR X8 SDRAM arrays). The NAS displays a warning, but everything works.
I'm not sure if it's a good one or not, but I'm sure it's a good one.
I'm going to be able to transfer my data and evaluate the caches now.
I'm going to add an inverter to it. :)
I use this nas for web hosting, administering my Windows Domain, and making virtual machines it is just perfect coupled with 32gb of ram.
In the same universe: nas
