Quick answer

For the Synology DS224+ (2 bays, drives up to 24TB each), fit NAS-rated CMR drives: Seagate IronWolf and IronWolf Pro, WD Red Plus and WD Red Pro, plus Toshiba N300. A SHR (1-drive fault tolerance) pool gives single-drive fault tolerance with usable capacity of total capacity minus the largest drive. The live table below shows the cheapest CMR drives by price per terabyte right now.

With 2x 8TB in Synology SHR you get about 7.28 TB usable and 1-drive fault tolerance. At the cheapest live NAS price per terabyte ($33.28/TB), filling these bays costs about $532.

Usable capacity is shown after binary and filesystem overhead (about 9%). Fault tolerance is not a backup; keep a separate copy of important data.

Which drives should go in the DS224+?

Choose NAS-rated CMR if

You want 24/7 reliability and a safe RAID rebuild
You are building a SHR (1-drive fault tolerance) pool
You store irreplaceable photos, documents or backups
Good fits: Seagate IronWolf and IronWolf Pro, WD Red Plus and WD Red Pro, plus Toshiba N300

Consider enterprise drives if

You want the lowest price per terabyte at high capacity
Extra noise and a little more heat are acceptable
You run the NAS in a cupboard or rack, not on a desk
Good fits: Seagate Exos and WD Ultrastar

Best drive size for the DS224+ by use case

Use case	Best choice	Why
Photo and document backup	2x 8TB CMR	Plenty of room for a mirror or SHR pool with headroom to grow.
Plex and media library	2x 16TB CMR	Large sequential files benefit from big CMR drives in one pool.
Maximum capacity	2x 24TB	Fills every bay for about 48TB raw before redundancy.

Setting up redundancy on the DS224+

The Synology DS224+ supports Basic, JBOD, RAID 0, RAID 1, SHR. For a 2-bay unit the sensible default is SHR (1-drive fault tolerance), where usable capacity is total capacity minus the largest drive.

Synology Hybrid RAID (SHR) is the easy option: it manages redundancy for you and, unlike classic RAID 5, it reclaims the surplus space when you mix drive sizes.

Use the capacity calculator below to see exact usable terabytes and the live cost to fill the bays.

Synology drive policy on the DS224+, a pre-2025 model

Synology's 2025 drive compatibility policy applies only to models launched from 2025 and is not retroactive, so it does not restrict the DS224+. Third-party NAS hard drives and SATA SSDs can be used for its storage pools.

A drive that is not on Synology's compatibility list shows as Unverified in Storage Manager and gets limited support. The DS224+ has no M.2 slots.

Checked on October 12, 2026. Sources: Synology Knowledge Center: Drive compatibility policies for systems from 2025 (DSM 7.3 and above); Synology Knowledge Center: Incompatible, Unverified and Unrecognized drive status.

Frequently asked questions

Can I mix drive sizes in the DS224+?

Yes. Because the DS224+ supports SHR, you can mix drive sizes and SHR reclaims most of the surplus that classic RAID would waste. RAID 5 and RAID 6 on this model still treat every drive as the smallest size.
