What reviewers say about the Seagate Expansion Desktop 8TB (STKP8000400)

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

Tested by PCWorld

Consistently 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

Commonly flagged

  • Copious ventilation makes it noisy in use
  • Requires an AC adapter (not bus-powered)
  • Slow compared to SSDs, especially in random performance

Where reviewers disagree 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.

It also delivers twice the sustained transfer rate of 2.5-inch external hard drives.
The Expansion Desktop is an excellent performer for the breed, offers excellent value, particularly at the sale prices, and highly recommended.
Note that the copious ventilation makes the Expansion Desktop rather noisy. Much noisier than the HDDs in my NAS boxes.
