Head-to-Head Comparison

Performance: Speed, Sustained Throughput, and Interface

The most significant difference between the SanDisk 4TB Extreme PRO and the SanDisk 4TB Extreme Portable lies in performance. The Extreme PRO leverages the USB 3.2 Gen 2×2 interface (20 Gbps), which enables it to achieve up to 2000 MB/s read and write speeds. This is nearly double the 1050 MB/s offered by the Extreme Portable, which uses the USB 3.2 Gen 2 interface (10 Gbps). In real-world terms, this means the Extreme PRO can transfer a 100 GB file in about 50 seconds, while the Extreme Portable takes closer to 95 seconds.

But speed isn’t just about peak numbers—it’s also about consistency. The SanDisk 4TB Extreme PRO features a forged aluminum chassis that acts as a heatsink, preventing thermal throttling during sustained workloads.
