The Samsung 990 Pro 4TB is the objective winner of this comparison, securing a victory in one specification while tying in all other categories. Its most significant advantage is a 9% better MSRP compared to the Samsung 990 Pro 4TB with Heatsink. Because the two drives share identical performance specifications across the remaining six fields, the base model provides the same core functionality as its counterpart while offering a more favorable cost structure for the consumer.

Choose the Samsung 990 Pro 4TB if you prioritize the 9% MSRP advantage and do not require the additional hardware included with the alternative model. Conversely, select the Samsung 990 Pro 4TB with Heatsink if your specific installation environment necessitates the integrated cooling solution provided by that version. Since both drives offer identical performance capabilities, your decision should be based solely on whether your system configuration requires the included heatsink or if you prefer the lower cost of the base drive.
