Write Performance Testing

Benchmark Results: These are pretty interesting benchmark results! The Seagate 4TB 5900RPM hard drive has higher read and write average transfer rates, but the WD Black 4TB drive has lower access times and much higher burst rates. Both drives were right around 130 MB/s for the read and write speeds, which is really moving for a hard drive of such a large capacity.

Benchmark Results: Running the built-in file benchmark test in HD Tune v5.50 shows how the drive performs with various file sizes. The WD Black 4TB 3.5″ desktop hard drive had higher sequential transfer speeds and higher IOPS in the 4K write tests.
