Quick answer

For the Synology DS925+ (4 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 4x 8TB in Synology SHR you get about 21.83 TB usable and 1-drive fault tolerance. At the cheapest live NAS price per terabyte ($33.28/TB), filling these bays costs about $1065.

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 DS925+?

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 DS925+ by use case

Use case	Best choice	Why
Photo and document backup	2x 6TB CMR	Plenty of room for a mirror or SHR pool with headroom to grow.
Plex and media library	4x 12TB CMR	Large sequential files benefit from big CMR drives in one pool.
Maximum capacity	4x 24TB	Fills every bay for about 96TB raw before redundancy.

Setting up redundancy on the DS925+

The Synology DS925+ supports Basic, JBOD, RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, SHR, SHR-2. For a 4-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 third-party drive policy, as of DSM 7.3

DSM 7.3, released October 8, 2025, lets 2025 Synology Plus, Value and J models install DSM and create storage pools on third-party hard drives and 2.5-inch SATA SSDs. The DS925+ is one of those 2025 models, so Seagate IronWolf, WD Red Plus, Toshiba N300 and similar drives can be used for its main storage pool.

M.2 NVMe is the exception. Creating an M.2 storage pool or an SSD cache on the DS925+ still requires a drive on Synology's compatibility list, and that list contains Synology SNV3400, SNV3410 and SNV5420 drives only.

Hard drives and 2.5-inch SATA SSDs that are not on Synology's compatibility list: supported for a new installation, for creating a storage pool and for migration. Synology still recommends listed drives.
M.2 NVMe SSDs that are not on the compatibility list: cannot create a storage pool or an SSD cache. They are accepted only when migrated, already in use, from another Synology system.
Any drive on Synology's incompatibility list: not supported for installation, storage pools or cache.

Checked on October 12, 2026. Sources: Synology Knowledge Center: Drive compatibility policies for systems from 2025 (DSM 7.3 and above); Synology press release, 8 October 2025: DiskStation Manager 7.3; Synology Products Compatibility List: DS925+, M.2 SSD via internal slot.

Frequently asked questions

Can I mix drive sizes in the DS925+?

Yes. Because the DS925+ 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.
