Please select product and accessory type
Note:
1. Please choose appropriate hardware for optimal compatibility. Prioritize products that have passed compatibility testing to ensure a better user experience.
2. Compatibility tests cannot cover every aspect of all products on the market, and changes in hardware or software may affect device compatibility and stability.
3. HDDs and SSDs have a defined lifespan. Make sure to check the status of your drives and take appropriate measures to avoid potential data loss.
4. It is not recommended to use SMR (Shingled Magnetic Recording) hard drives or mix old and new drives in the same RAID storage array, as this may lead to a risk of data loss.

UGREEN NAS Hard Drive & SSD Compatibility FAQs
Select your exact UGREEN NAS model, choose the accessory type, then search for the specific HDD, SSD, RAM module, or UPS model number. Compatibility can differ by NAS model.
An unlisted drive may still work, but UGREEN cannot guarantee stability or performance. For important data, choose a tested model from the compatibility list. If you still use an unlisted drive, back up your data first.
No. UGREEN NAS does not require branded drives. You can use 3.5-inch SATA drives, 2.5-inch SATA drives or SSDs, and M.2 SSDs where your NAS model supports them. Still, you should check the exact model number in the compatibility list before buying.
Use NAS-rated CMR hard drives for the best reliability in 24/7 storage and RAID setups. Desktop drives may physically work, but they are usually not the best choice for always-on NAS workloads. For buying guidance, read what drives should I use for a NAS.
CMR drives are better for NAS because they handle sustained writes and RAID rebuilds more predictably. SMR drives can slow down heavily during rewrites and may increase the risk of RAID instability or data loss. For NAS storage, use CMR drives whenever possible.
Whether you are using the UGREEN DXP2800 or the UGREEN DXP4800 Plus, we strongly suggest choosing CMR drives (like WD Red Plus or Seagate IronWolf) from our list to ensure your data remains safe and accessible.
No, it is not recommended to mix old and new drives in the same RAID array. Different capacities may work, but usable space is usually limited by the smallest drive. Use matched drives where possible and check usable capacity with the RAID Calculator before building or expanding a RAID pool.
RAM compatibility depends on the NAS model, memory type, capacity limit, and slot configuration. Do not buy RAM based only on DDR generation or capacity. Select your NAS model in the compatibility list first, then confirm model-level limits in the Product Specification Comparison.
Use the compatibility list to check whether a UPS is supported before buying. A suitable UPS should provide enough wattage and runtime for your NAS and should allow safe shutdown during power loss. For setup guidance, read how to choose the right UPS for your NAS.
Yes. Firmware updates can affect compatibility and stability. Keep your NAS firmware current, and also check firmware updates from the drive, SSD, RAM, or UPS manufacturer when troubleshooting recognition or stability problems. For NAS firmware files, use the Download Center.
