According to our NAS expert
This bundle includes 4 hard drives of 4TB with your NAS, so you can store files right away, make backups, or work in RAID.
You can place 2 M.2 NVMe SSDs in the NAS and create a fast cache memory so you can open often-used files faster.
The hard drives include 3 years of Seagate Rescue Services for data recovery.
You have to install the hard drives that are included with this bundle yourself.
This bundle doesn't include M.2 SSDs.
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.

Synology just works well. I bought this to replace the DS412 and transferring everything was very easy.

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.
