Portable 2TB SSD for professionals

The SanDisk Professional PRO-G40 2TB portable SSD delivers up to 2700MB/s read and 1900MB/s write speeds over Thunderbolt 3. Its IP68 rating, 4000lb crush resistance and 3m drop protection suit field workflows. An aluminum core manages heat during sustained transfers. The drive targets creators who need rugged, high-speed external storage.

Dual-mode interface and rugged build

Thunderbolt 3 (40Gbps) and USB-C (10Gbps) compatibility lets the drive work with current and older ports without extra adapters. The sealed enclosure achieves IP68 dust and water resistance while surviving 4000lb crush force and 3m drops. These physical protections replace the need for separate rugged cases. The aluminum core acts as a heatsink to maintain throughput under load.

Thunderbolt 3 bandwidth and USB fallback

Peak speeds of 2700MB/s read and 1900MB/s write require a Thunderbolt 3 host; USB-C 10Gbps ports will run slower. The drive uses a USB 3.0 interface specification, so it cannot reach Thunderbolt rates on USB-only connections. Buyers without Thunderbolt 3 ports will not see the advertised maximums. No internal drive details or encryption features are specified.

商品問答

Does the aluminum core require any maintenance to keep the drive cool?

The aluminum core is a passive heat spreader with no moving parts, so it needs no maintenance.

At 2700 MB/s read and 1900 MB/s write, what limits sustained throughput first?

The Thunderbolt 3 40 Gbps link caps sustained throughput before the internal NAND reaches its limit.

How loud and hot does the PRO-G40 get when running all day?

It has no fan, so it runs silently; the aluminum core keeps surface temperatures low during continuous transfers.
