The WD Gold 8TB datacenter drive has an official formatted capacity of 8,001,563,222,016 bytes. We checked that out by formatting it in NTFS using Microsoft Windows 7.
The actual formatted capacity was 8,001,427,599,360 bytes, which is about 136 MB lower than the official storage capacity. With about 338 MB allocated to the NTFS file system, the actual usable capacity remained slightly above 8 TB.
As expected from a premium, datacenter-grade hard disk drive, the platter profile of the WD Gold 8TB datacenter drive was phenomenal. There were absolutely zero dips in throughput that would signify a significant use of replacement sectors. Lots of them would be evidence of poor platter quality.
We also compared its platter profile to that of the 6TB WD Black – Western Digital’s top-of-the-line desktop hard disk drive. We can see that the denser platters allow the 6TB WD Black to achieve a higher throughput initially, but the 8TB WD Gold equalised it at around the 3.5TB point.
Maximum Surface Temperature
We monitored the surface temperature of seven hard disk drives during their benchmarks. The following chart shows their operating temperature range, from idle to maximum load. Please note that instead of giving you the absolute numbers, we are showing the temperature delta, which is the difference between the actual temperature and the ambient room temperature.
Despite packing 2 additional platters than the 6TB WD Black, the 8TB WD Gold drive was significantly cooler at full load. In fact, it ran cooler than the 4 TB WD Black Gen. 2, and the 4 TB WD Red Pro drives!
This reduced thermal output (and power consumption) is a key advantage of helium-filled hard disk drives like the 8TB WD Gold drive. When deployed in the hundreds or thousands in a datacenter, the lower energy costs of running them, and keeping them cool, will be very significant.
