According to our NAS expert
Store large business files and create backups of PCs with the Synology DS425+ NAS server. This NAS has 4 slots for hard drives and an 80TB storage space. This allows you to store backups of business laptops or PCs for your company. You can also place up to 4 SSDs of 2.5 inches or 3.5 inches in the NAS. There's also space for 2 M.2 NVMe SSDs in the DS425+. You can create various RAID setups with the NAS. This allows you to create 1 large storage space. With these hard drives, you can open frequently used files faster. Thanks to 2GB internal RAM and the Intel Celeron J4125 processor, you can use the NAS with 15 users at the same time. The NAS has 2 Ethernet ports with a 2500Mbps speed. That way, you can quickly transfer files to the DS425+.

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.

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.
