The Crucial T705 4TB is the objective winner of this comparison, securing five out of seven total specifications. Its most significant advantage is its storage capacity, which is 100% better than that of the alternative. While the Crucial T500 2TB holds its own in one category and ties in another, it cannot match the overall technical superiority demonstrated by the larger drive across the majority of the measured fields.

Users who prioritize maximum storage space should choose the Crucial T705 4TB to take advantage of its superior capacity. Conversely, the Crucial T500 2TB is the better option for buyers focused on the MSRP, as it offers a 74% advantage in that specific area. Selecting between these two drives depends entirely on whether your primary requirement is the expanded volume provided by the larger model or the cost efficiency offered by the smaller one.
