The Synology DS419slim is the latest in Synology's "slim" line of NAS servers which use 2.5-inch standard (laptop) hard drives instead of the 3.5-inch standard (desktop) drive.
As a result, the new server is super compact despite the fact it can house up to four internal drives. But in the world of network-attached storage devices, size matters -- the DS419slim indeed has modest hardware specs.
But the DS419slim is still a robust NAS system that is, in some aspects, better than a larger server. If you live in a cramped place, at $329 (disk-less), the DS419slim is still an excellent buy.
Synology DS419slim: Familiar design, modest hardware
The DS419slim is a bit of a personal story for me since I've had an older server, the DS411slim, since 2011. Upon getting the new server, I realized the two appeared almost identical.
Synology releases a slim server every couple of years. The DS414slim and DS416slim came out in 2014 and 2016, respectively, per Synology's naming convention.
All these slim machines are more similar to one another than not.
Synology DS411slim vs. DS419slim
In the case of the 411 and the 419, both are four-bay servers with back-facing drive bays. Both share the same drive trays -- you can use them interchangeably.
The two share the same front design with a USB port and an array of status lights. And both have the power button on the side and the ventilation fan on the underside.
There are just a few differences: The DS411slim uses USB 2.0 and has only one Gigabit LAN port. It has another USB and an eSATA port on the back. It also has a USB Copy button that you can press to quickly backup the content of a connected thumb drive onto the server.
The DS419slim, on the other hand, uses USB 3.0 and has two Gigabit LAN ports (with Link Aggregation support) and two additional USB ports on the back. It forgoes the USB Copy button and the eSATA port.
On the inside, the DS419slim has 512MB of DDR3 RAM compared to the 256MB of the DS411slim. Here's the disappointing part: You can't upgrade its memory. Having this little amount of memory -- many routers have the same or even more RAM -- the DS419slim is not suitable for intensive tasks, like media transcoding, hosting virtual machines, or heavy multitasking.
And the server's processing power is also limited. The DS419slim sports a Marvell Armada 385 88F6820 1.3GHz dual-core processor -- the lowest-end among those used in NAS servers released this year. Nonetheless, it's a lot better than the single-core 1.6Ghz Marvel Kirkwood 88F6282 processor of the DS411slim.
Easy hardware installation
The DS419slim is available disk-less. To add storage to the server, place a 2.5-inch drive on a tray, secure it with four little screws (included) -- you do need a screwdriver --and insert the tray into the server. Repeat that to add more drives.
There's no lock to keep the tray in place, but the tray fits in snugly, and you need to exert some force to pull it out. That, plus the fact the drive bays are on the server's back, limits the chances of accidental drive removal.
The server supports all standard 2.5-inch SATA hard drives. You don't even need to use the same drives or drives from the same vendor. If you want to get the best out of the server, I'd recommend Seagate's new Ironwolf 110 NAS solid-state drives (SSDs). These SSDs work with any NAS servers, but with a slim server like the DS419slim, they will fit right in -- you won't need to use caddies or converters like in a full-size system.
Multiple RAID options
The DS419slim can house up to four drives, but you need just one to start using it. For data security, though, it's recommended that you start with two. When multiple disks are in use, the server supports all applicable standard RAID options -- where the drives are bundled together to deliver better performance and data security if one of them dies.
On top of that, you can also use Synology Hybrid RAID (SHR). SHR automatically allows for a balance of redundancy and performance depending on the number of drives available.
For example, using two discs will be like a RAID 1, but if you use three or more disks, SHR is now similar to a RAID 5. With SHR, you can use internal drives of different capacities, enabling you to scale up the server's storage with ease.
Standard setup process
Running the latest version of Synology's DiskStation Manager (DSM) operating system, the DS419slim enjoys the same setup process as other Synology servers. Insert drives, connect the server to your network, turn it on, and run the Synology Assistant software from a connected computer. The rest is self-explanatory.
In my case, I tried moving drives from my old DS411slim over, and that worked without a hitch. All of my data and settings were there once I updated DSM to the version made for the DS419slim.
Overall, this server can be a bit of a learning curve if you're new to network storage. But if you have worked with web user interfaces before, or better yet, if you have some experience with Synology NAS servers (or routers, like the MR2200ac), you'll find the DS419slim manageable. It's not plug-n-play, but it's more fun than hard.

Synology DS419slim: A lesser NAS server
Due to the modest amount of RAM and overall hardware specs, the DS419slim doesn't have all that you can find in a full-size server like the DS1019+.
What is missing
However, the biggest shortcoming is the lack of support for the Btrfs file system; instead, you're stuck with the older EX4. This means you won't be able to set quotas for shared folders and use snapshot -- a form of shadow copy -- to protect data from unintended alterations, such as ransomware.
The server won't support virtual machines and video transcoding, either. Generally, if you're looking for a server to do heavy tasks, the DS419slim is not for you. This server only fulfills essential network storage needs and provides lightweight services.
But if you're wondering what you can do with the DS419slim? The answer is A LOT. The table below lists the main available functions of the server.
|Drive||A Dropbox-like service for data synchronization |
and access across all popular platforms.
It can handle up to 200 concurrent clients
and up to 100,000 hosted files.
|File Station||An essential virtual share and remote folders for the local network.|
|FTP Server||An advanced FTP function that supports|
custom FTP passive port range,
anonymous FTP, FTP SSL/TLS, and SFTP protocol,
boot over the network (TFTP and PXE,
and transfer logs.
|Cloud Sync||One or two-way synchronization service|
to public cloud storage providers,
supporting Alibaba Cloud OSS, Amazon Drive,
Amazon S3-compatible storage, Backblaze B2,
Baidu Cloud, Box, Dropbox, Google Cloud Storage,
Google Drive, hubiC, MegaDisk, Microsoft OneDrive,
OpenStack Swift-compatible storage,
Tencent COS, WebDAV servers,
and Yandex Disk.
|Hyper Backup||A versatile backup solution for backing up|
data both locally and to public clouds.
|Surveillance Station||A powerful security system that can handle |
up to 8 IP cameras
(two camera licenses included).
|VPN Server||Maximum connection: 10. |
Supported VPN protocol: PPTP,
|Mail Server||Mail Server protocol: POP3, SMTP, IMAP, |

Synology DS419slim: Good performance
I tested the DS419slim with several Seagate IronWolf 110 SSDs and regular hard drives (HDD). And in both cases, using SHR RAID, it performed admirably. When hosting SDDs, the server averaged some 105 MB/s for writing and 110 MB/s for reading. Its performance reduced to 64 MB/s and 78 MB/s, respectively, when I used regular hard drives.
The server was in no way the fastest I've seen -- it didn't hit the ceiling speed of the Gigabit connection used for the tests -- but fast enough for any home network storage needs.
The DS419slim's web interface was responsive, even when hosting hard drives. I was able to run multiple apps and move between them quickly.
For example, in my testing, when hosting two IP cameras via its Surveillance Station, the server was able to deliver similar data throughput performance to when it wasn't.
Synology DiskStation DS419slim's Rating
Fast and reliable performance
Robust operating system with lots of add-on features
Straightforward setup process and easy to use
Built for SSDs
Limited hardware specs and storage space
Memory maxes out at 512 MB
No support for the Btrfs file system
Only two camera licenses included
It's amazing what this little box can do. I used the Synology DS419slim for almost a month before publishing this review, and it grew on me. What I like most is the fact it's not noisy at all. I hardly noticed it in a quiet room, even when I used regular hard drives with it. When I used the SSDs, the server was near silent.
But truth be told, at times, I did miss the ability to run more advanced services. So, DS419slim is not a server for NAS enthusiasts -- its modest non-upgradeable hardware specs are too big of a constraint.
So, suppose you're looking to do a lot of multitasking or run resource-intensive workloads such as hardware transcoding, virtual machines, advanced file management/protection, or want a lot of storage space. In that case, this is not the server for you.
But if you're in the market for a compact system that will deliver all basic network storage needs and quite a bit more, the DS419slim is the little machine you've been waiting for.
