Easy Setup - Does What I Need 9/12/2020 7:29:51 AM

Pros: - Easy installation
- Simple interface

Overall Review: I'm not a very tech savvy person, I got this simply to run as a Plex Media Server and back up photos. For that simple reason, it runs fine. I've had 3 remote streams and a local with no issues.

Easy move from 1015 to this! 9/9/2020 5:02:27 AM

Pros: Took my disks, recognized them, rebuilt my config and I was on-line in short order!

Cons: Can't shrink volumes

Overall Review: Great tool in your toolbox. But, if you are planning on backing up VmWare, pay close attention to your volume configuration prior to putting anything on it. The typical configuration you would use for CIFS shares isn't going to work.

First experience with a NAS 7/28/2020 6:36:24 AM

Pros: Easy to set up and use. In minutes, everything was running.

- Plex works great to stream movies.
- I installed Docker and from there I set up Home Assistant and a Minecraft Server for the kids.

Cons: - I recommend you buy some additional ram to really enjoy the capabilities of this NAS.

Great NAS...Very Responsive...an EASY Upgrade Process from DS718+ 7/6/2020 10:36:00 AM

Pros: - Very Responsive Interface
- Upgrade from DS718+ was ++SEAMLESS++
- Adding new disks is easy
- Plug 'n Play Operation

Cons: - Process of adding new 10TB disk (SHR) can take 48 hours for checking parity scan, but this is normal for RAID or SHR management of a disk this size...10TB is a large disk.

Overall Review: - The greatest feature by far for Synology NAS products is the Disk Station Manager software and User Interface.
This feature alone provides:
-- Ease of Use
-- Confidence when managing data
-- Reduces errors since the interface is so easy to understand
-- Keeps user "out of trouble" or from making mistakes

Synology makes a SOLID product with software that is perfectly mated to the hardware, providing the user a seamless positive experience when operating the NAS.

Great Plex Player 6/28/2020 11:13:31 AM

Pros: When adding a Crucial 8GB 204-Pin DDR3 SO-DIMM DDR3L 1600 (PC3L 12800) Laptop Memory Model CT102464BF160B chip makes it a great NAS and plex player.

Cons: only two drives

Overall Review: I have a Synology DS418play for plex and needed to build another plex player for a friend I found that this was the route to go. Does the same thing as the 418play but only has two drives. Will defiantly work for what I need.
