Why Bestsellers Failed
The Bestsellers Failed. We found 3 bestselling external hard drives that market themselves as high-speed but rely on slow HDD technology. Here's the evidence:
Seagate Portable 2TB HDD
Marketed for convenience, but it's a mechanical HDD with speeds around 100-140MB/s, 10-20 times slower than high-speed SSDs (1000+ MB/s). USB 3.0 interface can't overcome HDD limitations.

Aiolo Innovation 1TB HDD
Claims 'super fast' transfers, but specs show 110-133MB/s read, 103MB/s write as a mechanical HDD. This is inadequate for high-speed needs, being 10x slower than SSDs.
View source ↗
WD My Passport Ultra 5TB
Marketed with USB-C compatibility, but it's a mechanical HDD with speeds under 150MB/s. Rotational speed listed as 1 RPM (likely error), confirming slow HDD tech unfit for high-speed.
