Compare two real purchase candidates against one recording load, separating missing official evidence from directly disqualifying limits.

XRN-3210RB2 SPZ-10300TW / WD101PURA-64B5KY0
RAID6 · 4 + 1 spare
Revision 11.14 marks the RAID row for the XRN-6410RB2 group, which includes XRN-3210RB2, as tested with WD101PURA-64B5KY0. The checked Korean listing marks it discontinued, so it is a compatibility reference rather than a current purchase candidate and the calculator avoids it.
Official support unconfirmed · Verify before purchase
XRN-3210RB2 ST10000VE001
RAID6 · 4 + 1 spare
ST10000VE001 is a CMR surveillance drive, but Revision 11.14 does not directly mark its column as tested in the XRN-6410RB2 group RAID row. Do not infer RAID 6 compatibility without exact-SKU confirmation.
Hanwha Vision Revision 10.9 history and the Revision 11.14 matrix directly mark ST8000VX004 RAID mode as unsupported for the XRN-6410RB2 group. Do not confuse this with non-RAID support.
There is no immediate purchase recommendation. The exact officially compatible reference is discontinued in the checked Korean listing, while the currently listed alternative lacks confirmed RAID 6 compatibility. The calculator excludes discontinued items.

Please confirm whether the XRN-3210RB2 officially supports a RAID 6 array using four Seagate ST10000VE001 10 TB drives. If supported, please provide the supported XRN-3210RB2 firmware version, the exact HDD Part Number and any required HDD firmware version, plus the official RAID 6 test or compatibility document. This request concerns this exact NVR, HDD SKU, and RAID 6 combination rather than a related model group or single-drive use.
Evidence needed to promote this candidate: exact NVR model, supported NVR firmware, HDD Part Number and firmware, RAID 6 support, and an official document.
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, workload, or evidence URL is missing.
Eligible: only candidates with every required fact and official evidence enter the estimated five-year cost recommendation.
Official silence is neither compatible nor incompatible. This tool does not infer an unverified specification. Before purchase, confirm that the official compatibility page names the exact NVR model and capacity-specific HDD SKU.
Cost-model limits
Upfront cost includes the NVR plus installed and spare HDDs. Estimated five-year cost adds a simple statistical expectation: post-warranty years × AFR × installed-drive price. It is not a lifetime forecast and excludes recovery, downtime, shipping, price changes, and correlated failures.
RAID is not a backup. Export incident footage to another device before rolling retention overwrites it, then test playback.
