CCTV NVR and HDD Purchase Comparison

Compare two real purchase candidates against one recording load, separating unknown technical conditions from directly disqualifying limits.

Korean-market official evidence ledger

Example ledger comparing exact 10 TB HDD SKUs for a Hanwha Vision XRN-3210RB2 RAID 6 configuration using official specifications and compatibility evidence. Official evidence check date: 2026-08-26.

Ledger status	Exact NVR and HDD	Layout	Inclusion, verification, or exclusion reason	Sources
Official compatibility reference	XRN-3210RB2 SPZ-10300TW / WD101PURA-64B5KY0	RAID6 · 6 + 1 cold spare	Hanwha Vision Revision 11.14 marks WD101PURA-64B5KY0 as tested in the RAID row for the XRN-6410RB2 group that includes XRN-3210RB2. The RAID 6 example uses six HDDs per official guidance; the additional unit is explicitly an external cold spare that does not occupy a bay. CMR, warranty, and workload for this exact OEM SKU remain unconfirmed by the linked official material.

Official support unconfirmed · Verify	XRN-3210RB2 ST10000VE001	RAID6 · 6 + 1 cold spare	ST10000VE001 is identified as a CMR surveillance drive in its official data sheet, but Revision 11.14 does not directly mark its column as tested in the XRN-6410RB2-group RAID row. The RAID 6 example uses six HDDs plus one external cold spare; exact-SKU compatibility remains unknown.

Avoid	XRN-3210RB2 ST8000VX004 (2M1101)	RAID6 · 6 + 1 cold spare	Hanwha Vision Revision 10.9 history and the Revision 11.14 matrix mark ST8000VX004 RAID mode as unsupported for the XRN-6410RB2 group. The physical example is corrected to six RAID HDDs plus one external cold spare, but this HDD combination remains excluded; non-RAID support is not RAID support.

Decision rules

Avoid: capacity, channels, incoming bandwidth, bays, supported capacity, or workload limits fail, or SMR, incompatibility, or unsupported RAID is directly confirmed.
Verify: the exact model, CMR, surveillance rating, official RAID and HDD compatibility, warranty, AFR, or workload is unknown.
Eligible: among candidates that meet every entered technical condition, the comparator prioritizes the smallest capacity surplus and then the fewest drives.

Official silence is neither compatible nor incompatible. This tool does not infer an unverified specification. Confirm that the official compatibility page names the exact NVR model and capacity-specific HDD SKU before finalizing a configuration.

RAID is not a backup. Export incident footage to another device before rolling retention overwrites it, then test playback.
