Our Verdict
The UnionSine 16TB is the highest-capacity drive in this category at $479.99 ($30.00/TB), which is also the lowest per-terabyte cost among desktop external drives here. It is a desktop form-factor drive requiring AC power. At $30.00/TB it undercuts the WD My Book 8TB ($298.26, $37.28/TB) by 19.5% per terabyte, delivering twice the capacity for 1.6x the price. The trade-off is brand maturity: UnionSine is not a tier-1 storage brand, and with 862 reviews at 4.3 stars, failure-rate data is limited compared to WD with 13,000+ reviews on the My Book alone. For cold archival storage where data exists elsewhere and a drive replacement is manageable, the per-TB savings are real. For a primary or sole backup of irreplaceable data, the WD My Book 8TB's brand track record is worth the higher per-TB cost. Buy the UnionSine when maximum capacity and minimum cost per terabyte are the only criteria and redundancy already exists.
