Synology DiskStation DS225+ 2-Bay Desktop NAS Enclosure

The two-bay Synology most small offices end up buying — shared files, automatic backup and Synology's DSM software, on about 17 W and under 20 dB(A). Intel Celeron J4125 quad-core, 2 GB of DDR4 expandable to 6 GB, and a 2.5GbE port alongside a Gigabit one. Supplied without drives — you choose and budget for those separately.

DSM — the reason people buy Synology

DiskStation Manager handles file sharing, Active Backup for Business, Synology Photos, Drive and Surveillance Station from one web interface that non-specialists can actually run. Btrfs snapshots let a share be rolled back to a point in time.

2.5GbE without recabling

The 2.5GbE port runs over the CAT5e already in the wall, so the speed step needs no new cabling. A second Gigabit port sits alongside it for separating traffic or keeping a management path open.

19.6 dB(A) and about 17 W

One 92 mm fan with a quiet mode, measured by Synology at 19.6 dB(A), drawing 16.98 W in use and 6.08 W with the drives asleep — quiet and cheap enough to leave running in an occupied room.

ProcessorIntel® Celeron® J4125 4-core / 4-thread, 2.0 GHz base and 2.7 GHz turbo
CPU Architecture64-bit
System Memory2 GB DDR4 non-ECC (fitted)
Maximum Memory6 GB (2 GB soldered plus a 4 GB module)
Memory Slots1 free SODIMM slot
Encryption EngineYes — hardware encryption engine
Drives IncludedNo — supplied as a diskless enclosure. Drives are ordered separately.
Drive Bays2 x 3.5-inch SATA HDD or 2.5-inch SATA SSD
Drive CompatibilitySynology guarantees full functionality and support only for drives on its compatibility list
Hot-SwappableYes, on both drive bays
SSD CacheSupported with compatible SSDs. There are no M.2 slots on this model, so a cache SSD occupies one of the two drive bays
RAID LevelsBasic, JBOD, RAID 0, RAID 1 and SHR — the levels two bays can support. SHR-2, RAID 5, 6, 10 and F1 need more bays
Maximum Volume Size200 TiB maximum single volume (a DSM limit, far above what two bays can hold)
Network Ports1 x 2.5GbE RJ45 and 1 x Gigabit RJ45 — two ports, two different speeds
Wake on LANWake on LAN and Wake on WAN supported
Jumbo FrameSupported on the 2.5GbE port. Synology limits the Gigabit port to a 1,500-byte MTU, so no jumbo frames there
USB Ports2 x USB 3.2 Gen 1, with USB Copy
Link Aggregation / VLANThe two ports run at different speeds, so link aggregation cannot combine them into one faster link. Use the second port for separate traffic or failover
Operating SystemDSM 7.2 (DiskStation Manager)
Client Operating SystemsWindows, macOS and Linux
File ProtocolsSMB, AFP, NFS, FTP, WebDAV and rsync
Internal File SystemBtrfs and ext4
SnapshotsBtrfs snapshots through Snapshot Replication, with replication to a second Synology

Specifications are provided by the manufacturer and may be updated or changed without prior notice. AtomOffice is not responsible for any discrepancies between the information shown here and the manufacturer's official documentation.

  • The DS225+ ships as a bare enclosure. Budget for two SATA drives on top, and check them against Synology's compatibility list before ordering — Synology only guarantees full functionality and support for drives on that list.
  • Memory is part-soldered: 2 GB is fixed to the board and there is a single free slot, giving a 6 GB ceiling with a 4 GB module. It is not a pair of matched slots, and Synology will not provide full warranty or technical support if a non-Synology module is fitted.
  • The two network ports are different speeds — one 2.5GbE and one Gigabit — so they will not combine into a single faster link. Synology also notes the Gigabit port is limited to a 1,500-byte MTU, which rules out jumbo frames on that port.
  • The warranty is 3 years and can be extended to 5, but the extension SKU is regional: in the UAE that is EW201. 'Extended Warranty Plus' is sold only in Europe and North America, so do not budget for it here — ask us and we will quote the right one.
  • The DS225+ is supplied as a diskless enclosure. Hard drives and SSDs are not included and are ordered separately — ask us and we will quote drives alongside the unit.
  • One shared drive for the whole office, instead of files living on whichever laptop made them.
  • Active Backup for Business protects PCs, Macs and servers without a per-seat licence.
  • Btrfs snapshots roll a share back to a point in time, which is what actually saves you after ransomware.
  • Under 20 dB(A) and about 17 W, so it can sit in the office rather than needing a cupboard.

D4NS01-4G

Synology 4 GB DDR4 non-ECC SODIMM. The one supported memory upgrade, taking the unit from 2 GB to its 6 GB ceiling. Synology withholds full warranty and support if a non-Synology module is used.

HAT3300 Series

Synology Plus Series 3.5-inch SATA drives, validated for this enclosure and the straightforward choice for a two-bay unit doing file sharing and backup.

HAT5300 Series

Synology Enterprise Series 3.5-inch SATA drives, for higher workloads or where a longer validated service life matters more than cost per terabyte.

SAT5200 Series

Synology Enterprise 2.5-inch SATA SSDs, for an all-flash build or as the cache drive — bear in mind a cache SSD uses one of the two bays on this model.

No. It is sold as a diskless enclosure, so you choose the drives to suit the capacity and budget you need. It takes two 3.5-inch SATA hard drives or 2.5-inch SATA SSDs. Synology only guarantees full functionality and support for drives on its compatibility list, so check there first — we are happy to quote validated Synology HAT3300 or HAT5300 drives alongside the unit.

One 4 GB module, taking it to 6 GB. The first 2 GB is soldered to the board and there is a single free slot, so this is not a matched pair of sockets. Use the Synology D4NS01-4G module — Synology states it will not provide full product warranty or technical support where a non-Synology module has been fitted.

Not into one faster link. The DS225+ has one 2.5GbE port and one Gigabit port rather than a matched pair, so link aggregation cannot usefully bond them. The second port is still worth having for separating traffic, keeping a management path open, or failover. Note too that Synology caps the Gigabit port at a 1,500-byte MTU, so jumbo frames only apply to the 2.5GbE port.

Basic, JBOD, RAID 0, RAID 1 and SHR. DSM as a platform also offers SHR-2, RAID 5, RAID 6, RAID 10 and RAID F1, but those need three or four drives, so they are not available on a two-bay unit. For most small offices RAID 1 or SHR is the right answer — one drive can fail without losing data.

Not Sure How Many Bays or Which Drives?

Tell our UAE team what you are storing, how fast it needs to be and how much you can afford to lose, and we will size the NAS, the drives and the RAID level with you — including when a smaller unit is the right answer.
