## What reviewers say

Only one whitelisted tester, PCWorld, reviewed the Seagate Expansion Desktop line hands-on, and it praised the low price-per-terabyte, huge capacity and 2.5-inch-beating speed while flagging noise and the required AC adapter. Its ~280MBps benchmark was measured on the 16TB sibling, not the 8TB. AppleInsider and others aren't whitelisted. (Based on 1 review, 2024-06-20.)

Praised: Super-low price per terabyte and strong value, especially at sale prices; Up to 24TB capacity; twice the sustained transfer rate of 2.5-inch external HDDs; Minimal heat buildup despite the mechanical drive.
Flagged: Copious ventilation makes it noisy in use; Requires an AC adapter (not bus-powered); Slow compared to SSDs, especially in random performance.
Disagreement: Only one whitelisted source (PCWorld), so no cross-source comparison is possible; its speed benchmark was run on the 16TB capacity, so the exact 8TB (STKP8000400) throughput remains unverified by any whitelisted tester.
