Transfer Rate Range

This chart shows you the range of platter-to-buffer transfer rates from the innermost track to the outermost track. In other words, it shows you the range of disk transfer rates of the hard disk drives (from minimum to maximum).

The 8TB WD Gold drive has an official peak throughput of 205 MB/s, which was confirmed by our tests. In fact, it actually peaked at 209 MB/s. While that puts it ahead of most of the competition, it was still slower than the 6TB WD Black.

This is because the 8TB WD Gold uses platters with slightly lower areal density (about 1,142 GB per platter) than the 6TB WD Black, which boasts 1,200 GB per platter.

 

Business Disk WinBench 99

The 8TB WD Gold datacenter drive is not optimised for desktop applications, so it’s no wonder that it isn’t the fastest drive in this test. Even so, the 8TB Gold datacenter drive did reasonably well, coming within 12% of the 6TB WD Black.

High-End Disk WinBench 99

Again, the 8TB WD Gold was fast, but it was not exceptionally fast because it’s not optimised for desktop applications.
