For your needs of replacing and improving on a 4TB storage setup, there are a few options to consider. DSM7+ on Synology NAS supports LUKS, and you can use a USB drive or another NAS on the network to store the encryption key for added security against physical theft. The DS220j may not be sufficient for 5GbE, so it's better to consider the DS220+ or the new DS224+ for better performance in this scenario.
However, if you require simple file storage and backups via 1GbE or 2.5GbE LAN, the DS220j can still serve that purpose effectively. Additionally, you can explore the DS423+ with two bays, and if you replace the HDDs with SSDs, it will significantly improve the speed even on the J series NAS. On the other hand, the Plus series offers extra features such as snapshots, virtualization, Docker, and Active Backup for Business, making them more versatile for various applications. Ultimately, it depends on your budget and specific requirements.
