The Western Digital WD Black SN8100 4TB is the objective winner of this comparison, securing more individual specification victories than its competitor. While both drives share several identical technical attributes, the most significant advantage offered by the Western Digital WD Black SN8100 4TB is its storage capacity, which is 100% greater than that of the Kingston Fury Renegade G5 2TB. This makes the former the superior choice for users prioritizing maximum data volume.

Users who require extensive storage space for large libraries or professional workloads should select the Western Digital WD Black SN8100 4TB to take advantage of its doubled capacity. Conversely, the Kingston Fury Renegade G5 2TB is the better option for budget-conscious buyers, as it holds a 53% advantage in MSRP. Choosing between these two drives depends entirely on whether your primary requirement is the lower cost of the Kingston or the higher capacity of the Western Digital.
