Unclear whether it depends on my ignorance or the fact that it is difficult to find sensible documentation to prepare.
Bought my DS218Play and two 6TB hard disks that I installed before I started the device. Of course, chose to install DSM as suggested. When the installation was complete, NAS was configured with Raid 1, which I would not have asked for. So, just shut-off and wipe out one disk. Now I hope I can add disk number 2 after installation and get my desired space of 12 TB.
Surely a great NAS, but the installation process is completely useless because you can not choose how to install the disks.
Appears possibly with additional complaints after one-time testing. Currently, it's only 5 stars.
After a few days of use, it returns from this "user-friendly" NAS.
The interface is a nightmare also for a somewhat experienced user and some things simply can not be solved even though it's going to go. Was able to change my two 6TB disks to a 12TB because it could not get either RAID0 or JOBD.
Two hours went to try to configure the device for external access. My router is not in Synology's list and I can easily open 40's of the router manually.
I recommend this product only to people who are looking for a heavy headache and several sleepless nights. Changes my rating from 5 stars to 1.
