Description

Create a small server with the Synology DS225+ + Seagate IronWolf 4TB Duo Pack. This bundle includes 2 Seagate IronWolf hard drives with a 4TB storage capacity per drive. This way, you can store all your files right away on one drive and make backups on the other one. The DS225+ has 2 Ethernet ports. Via the 1 GbE port, you can connect older devices. The 2.5 GbE port has a faster connection than the 1 GbE port, which is useful when you transfer a lot of files. For example, datasets, 4K videos, or an entire photo library. The NAS supports 512 user accounts and 128 shared folders. Thanks to this, you and your colleagues work with the NAS at the same time without problems. The NAS also performs 2 tasks at the same time, thanks to the Dual-Core Intel processor. This way, you're not bothered by slowdowns while you work. The Seagate IronWolf drives have a 5900RPM rotation speed on average. Thanks to this, you can quickly load files. With this bundle, you get 8TB of storage. This is enough for use at home or at a small office. You receive 3 years of Seagate Rescue Services for data recovery with the hard drives.

a downgrade from its predecessor.

Synology software
Not two, but only 1x 2.5g port

It's a good thing Synology lifted its hard drive restrictions; otherwise, this product would be a clear no-go. You have to install the correct drivers for Intel's QSV yourself (via SSH or a script). And contrary to the product description here, the device only has one 2.5g port.

If you're not yet part of the Synology ecosystem, avoid it. The jump from the DS224+ to the DS225+ doesn't bode well for the future. With the exception of that single 2.5g port, this device is, on paper, the same as—and in reality, a downgrade from—its predecessor.

Ideal storage for home

Easy installation
No extensive knowledge required
Safe

After six years, it was time to upgrade my old Synology NAS. The drives were a bit newer, so I could keep them. Of course, I watched tons of tutorials on how to migrate, but it was a breeze. It's really just a matter of transferring drives and you're done. The DS225+ is fast, not exactly quiet (with the ventilation), but certainly acceptable.

DS224+ with 1x 2.5g LAN, but without QSV drivers.

Synology software
No Intel Quick Sync Video drivers

Except for one (no, not two Coolblue!) 2.5g port, this is the same hardware as the DS224+. There's nothing wrong with that per se, except for the price, for example, for a CPU that Apple would label as "Vintage."

I wouldn't advertise the Plex server too loudly, because the Intel drivers are nuked in this version. QuickSync Video is no longer supported (which was the only good reason to use an old Intel CPU anyway), making hardware transcoding in Plex impossible. (Or any other media server that can use QSV, like Jellyfin).

2GB of RAM isn't enough to run an extensive home assistant, a stack of Docker containers, or even a single VM without an upgrade.

Fortunately, the restrictions on hard drive brands/types have been reversed, so I don't need to comment on that.

For a NAS, it's a far too expensive solution, and as a small home server, incompetent for a layperson.

Intel drivers with QSV support can be installed, and RAM can also be added.

Want to use this NAS with HDDs? Buy the DS224+. Don't have any experience with Synology (yet)? Then you can skip this one.
