SanDisk Pro-G40 4 TB Thunderbolt portable SSD

SKU CH-MTB5-WFG90

External SSD with Thunderbolt 3 reaching 3000 MB/s for 4 TB of storage

  • 4 TB capacity for large media libraries
  • Thunderbolt 3 interface at 40 Gbps
  • Up to 3000 MB/s sequential read speed
  • Pre-formatted exFAT for cross-platform use
  • Includes Thunderbolt 3 cable and quick start guide

Professional portable Thunderbolt SSD

The SanDisk Pro-G40 is a 4 TB external solid-state drive built around a Thunderbolt 3 connection rated at 40 Gbps. It ships pre-formatted in exFAT and includes the required Thunderbolt 3 cable plus a quick start guide. The compact enclosure targets creative professionals who move large media libraries between workstations.

Suited to single-drive Thunderbolt workflows

Editors and photographers who need sustained 3000 MB/s transfer rates over a single Thunderbolt 3 link will benefit from this drive. Buyers who require multiple drives for RAID arrays or who need USB-only compatibility without a Thunderbolt port should consider other options.

40 Gbps Thunderbolt 3 interface decides fit

The 40 Gbps Thunderbolt 3 interface is the specification that determines whether this SSD matches the host system. Only computers equipped with a Thunderbolt 3 or Thunderbolt 4 port can deliver the rated 3000 MB/s throughput.

Questions about this item

How do I install the SanDisk Pro-G40 4 TB Thunderbolt portable SSD, and what step do people often miss?

Connect the supplied Thunderbolt 3 (40Gbps) cable to a Thunderbolt 3 or 4 host port; the drive ships formatted exFAT so it mounts immediately, but users often plug it into a standard USB-C port and lose the 3000 MB/s speed.

What maintenance or replacement will the SanDisk Pro-G40 4 TB Thunderbolt portable SSD need later?

No scheduled maintenance is required; the solid-state design has no moving parts, so only the Thunderbolt cable may need replacing if damaged.

What limit appears first on the SanDisk Pro-G40 4 TB Thunderbolt portable SSD during sustained use?

The 3000 MB/s sequential throughput ceiling is reached before any thermal throttle under continuous heavy workloads.
