The IronWolf drives are designed to run in NAS enclosures, and they come with vibration protection and 24/7 reliability.
The NAS itself comes in at a reasonable price, but that's just for the diskless enclosure - you will have to buy the hard drives, like Seagate's 4TB IronWolf hard drive, separately.
The DS220j has two drive bays, and each bay can accommodate hard drives up to 16TB. If you're looking at a budget model to get started, the DiskStation DS220j is a great option. The brand makes the best home NAS enclosures and sells dozens of enclosures across all price points. If you're looking to build a NAS for backing up data from all the phones and Windows and macOS machines in your house or storing your audio and media library, Synology is the ideal place to start.
