UGREEN NAS Cost Calculator: Drives, RAID & Usable Storage
Select a UGREEN NAS, a current NAS hard drive, the number of drives and a RAID level. The calculator estimates total purchase cost, raw storage, usable capacity, fault tolerance and cost per usable terabyte.
What the calculator includes
The total combines the selected NAS enclosure, the selected number of identical hard drives and any optional hardware amount you enter. Live Amazon US prices are prefilled when fresh offers are available, but every price field remains editable.
The capacity estimate follows UGREEN’s RAID-planning guidance by subtracting approximately 16GB for the UGOS Pro system partition, then shows both decimal TB and approximate binary TiB. Actual capacity will vary with file-system metadata and the installed drive models.
How RAID capacity is estimated
RAID 0 and JBOD use the selected drives’ combined capacity without drive-failure protection. RAID 1 mirrors two drives. RAID 5 uses one drive equivalent for parity, RAID 6 uses two, and RAID 10 mirrors striped drive pairs.
RAID is not a backup. Keep a second independent copy of files that cannot be replaced.
UGREEN NAS cost examples
Two-bay RAID 1
A DXP2800 or DH2300 with two matched 12TB drives provides about 12TB before overhead and can continue operating after one drive failure.
Four-bay RAID 5
A DXP4800 Plus or DH4300 Plus with four matched 12TB drives provides about 36TB before overhead and tolerates one failed drive.
Four-bay RAID 6
Four matched 12TB drives provide about 24TB before overhead and can tolerate two failed drives, at the cost of lower storage efficiency.
Calculator questions
Why is usable capacity lower than the number on the drives?
RAID protection, system partitions, file-system metadata and decimal-to-binary unit conversion all reduce the capacity displayed by the operating system.
Can I mix different drive sizes?
Many configurations allow it, but standard RAID generally uses the smallest drive as the capacity basis. Matching capacities avoids paying for space that the array cannot use.
Does the calculator guarantee compatibility?
No. It estimates cost and capacity. Verify every exact hard-drive model number in UGREEN’s live compatibility list before buying.
Are taxes and shipping included?
No. The estimate uses listed product prices and your optional extra-hardware amount. Taxes, shipping, coupons and checkout changes are not included.
