The Crucial T705 4TB is the objective winner of this comparison, securing more individual specification victories than its counterpart. While both drives share several identical technical attributes, the Crucial T705 4TB holds a significant advantage in total storage capacity, offering 100% more space than the smaller model. This substantial increase in capacity provides the primary edge for the larger drive, making it the superior choice for users prioritizing maximum data volume.

Users who require extensive storage for large libraries or professional workloads should select the Crucial T705 4TB to take advantage of its doubled capacity. Conversely, the Crucial T705 2TB is the better option for budget-conscious buyers, as it maintains a 65% advantage in MSRP. Choosing between these two components depends entirely on whether your primary requirement is the lower cost of the 2TB model or the expanded storage space of the 4TB version.
