UGREEN NASync DH2300: capacity calculator
By Devin Chua · Data checked by Owen Nakamura · Updated In the UGREEN NASync DH2300 with 2 × 8 TB in RAID 1 you keep 7.28 TiB usable (8 TB in drive-maker terms), surviving 1 drive failing. The calculator below is preset to the 2 bays and the RAID types UGOS Pro actually offers on this model (there is no SHR equivalent here), with the cost to fill in Canadian dollars from live Amazon.ca prices.

Preset for the DH2300: 2 bays, and only the RAID types this model actually supports.
RAID 1 (Mirroring)
That is 8 TB the way drive makers label capacity. Your NAS shows you the smaller number because it counts in powers of two.
Drives: from CA$1,008 for 2 × 8 TB (CA$63.01/TB overall)
What to know about the DH2300
The cheapest NASync model and deliberately lean: 1-gigabit networking, 4 GB of soldered RAM, no Docker. Watch out for reviews that quote RK3588C, 8 GB and 2.5GbE: those are the DH4300 Plus specs, not the DH2300.
The DH2300 at a glance
| Bays | 2 × 3.5-inch SATA |
|---|---|
| Maximum raw capacity | 64 TB 2 × 32 TB hard drives, per the manufacturer |
| Processor | Rockchip RK3576, ARM 8-core (Cortex-A72 and A53) |
| Memory | 4 GB stock, LPDDR4X, soldered Soldered, not upgradeable |
| M.2 NVMe | none No M.2 slots |
| Network | 1 × 1GbE |
| RAID types | Basic, JBOD, RAID 0, RAID 1 |
| Third-party drives | unrestricted Open. UGREEN mandates no drive brand. The compatibility list is a recommendation, not a lock. |
No SHR: mixed drive sizes cost the DH2300 capacity
UGOS Pro has no flexible RAID like Synology's SHR. Put one 16 TB drive with three 8 TB drives in the DH2300 and it counts 8 TB per drive — eight terabytes sit idle. So buy matched drives for the DH2300, or work the loss out in the calculator above before you commit to this model; the "unused" figure shows exactly how much you would lose.
Two bays means RAID 1 in practice on the DH2300
With two drives there is no sensible alternative to RAID 1 on the DH2300 (or SHR with two drives, which is arithmetically the same). You pay half your capacity for fault tolerance: 2 × 8 TB becomes 8 TB, not 16. RAID 5 needs at least three drives and is not available here. For more capacity per dollar without giving up safety, a four-bay model is the move.
Which drives belong in the DH2300?
CMR NAS drives rated for 24/7 use — Seagate IronWolf, WD Red Plus, Toshiba N300 or their Pro variants. Our drive picks for the DH2300 with live prices show which of those currently offers the best capacity per dollar. If you are working back from a target capacity instead, the drive-count calculator works out how many drives you need.
Frequently asked questions
How much storage is left in the DH2300 with 2 × 8 TB?
About 7.28 TiB usable — 8 TB in drive-maker terms — computed in RAID 1, the sensible default for this model. It survives 1 drive failing. The gap from the 16 TB raw goes to parity.
Which RAID types does the DH2300 support?
UGOS Pro offers Basic, JBOD, RAID 0, RAID 1 on the DH2300. There is no flexible RAID like Synology's SHR here, so mixed drive sizes cost the DH2300 real capacity — every drive counts only as much as the smallest in the array.
Can I put third-party drives in the DH2300?
Open. UGREEN mandates no drive brand. The compatibility list is a recommendation, not a lock.
How much memory does the DH2300 take?
It ships with 4 GB (LPDDR4X, soldered). Soldered, not upgradeable The memory is soldered and cannot be upgraded.
Why does my NAS show less than the calculator says?
Because the maker and the OS count differently. A drive maker calls one trillion bytes a TB; the NAS counts in powers of two and calls that a TiB — about 9 percent less. That is why this calculator leads with the TiB figure: it is the number you will read off the screen.
