Description

Store all your media, documents, and other files in 1 place with the Synology DS425+ + Seagate IronWolf 8TB Duo Pack. This bundle includes 2 Seagate IronWolf hard drives with an 8TB 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 DS425+ 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. You can also place 2 NVMe SSDs in the NAS for a fast cache memory or expand the RAM when you use the NAS with multiple people at the same time. The Seagate IronWolf drives have a 5900RPM rotation speed on average. Thanks to this, you can load files. With this bundle, you get 16TB of storage. This is enough for use at a medium-sized office or when you want to store a lot of 4K media in 1 place. You receive 3 years of Seagate Rescue Services for data recovery with the hard drives.

Unfortunately, only Synology HDDs are supported

Trusted Synology software
From the 2025 models onwards, only Synology HDDs are supported

My migration from a Synology DS415+ to this Synology DS425+ went smoothly. I transferred the existing WD Red HDDs, and they work in the new NAS (although the drive status remains "Migrated from another system"). If I wanted to add a new WD Red HDD, that's not possible (short of a hack). In that case, I'd have to opt for a Synology HDD.

Complete NAS from Synology

Migration from DS415play works great
Fast
DSM
Price maybe

Transferring drives from the DS415play to the 425+ was easy. They are Seagate and WD drives, so not officially supported by Synology, but they were immediately recognized and migrated. Data and settings were transferred without loss. DSM 7.3 was installed before the migration, so thankfully the non-Synology drives worked just fine.

Otherwise, it's a fantastic, fast NAS. I highly recommend it.
