This speed is significantly higher than standard USB 3.0 drives. It suits professionals who need to move gigabytes of data quickly. Note that actual speeds depend on your host device capabilities.
Interface: Thunderbolt 3, USB-C
The PRO-G40 supports both Thunderbolt 3 and USB-C interfaces. Thunderbolt 3 offers the highest bandwidth for maximum speed. USB-C provides broader compatibility with devices that lack Thunderbolt ports. You can connect this drive to various laptops and desktops.

Storage Capacity: 1TB
This model provides 1TB of total storage space. You can store thousands of high-resolution photos, hours of 4K video, or extensive software libraries. This capacity is ideal for users who need substantial local storage without relying on cloud services. Compare this to smaller 512GB models if you have limited space requirements. The 1TB size balances ample room with a manageable physical footprint for external drives.
Cooling: Cool aluminum core
The drive features an aluminum core designed to pull heat away from the internal components. This passive cooling helps maintain consistent transfer speeds during long file transfers. You avoid thermal throttling, which can slow down performance in smaller, plastic-cased drives. This design is particularly useful for sustained workloads. It ensures the drive remains stable and reliable during intensive professional tasks.
Form Factor: External
This is an external solid-state drive, meaning it connects via cable rather than internal slots. You can easily carry it between workstations or travel with your data. It does not require opening your computer to install. This form factor offers flexibility for users who need portable, high-speed storage. It is distinct from internal NVMe drives that reside inside a laptop or desktop chassis.
Design and build quality
The listing describes a rugged exterior built for tough environments. It features an aluminum core that pulls heat away from the internal drive. This cooling method helps maintain high transfer speeds during long work sessions. The finish is black, and the unit is pre-formatted in exFAT for immediate use on PCs. You do not need to format it before starting your work.
The dimensions are 4.36 inches in length, 2.28 inches in width, and 0.47 inches in height. It weighs 4.32 ounces. This compact form factor makes it easy to slip into a camera bag or laptop sleeve. The low profile ensures it does not stick out awkwardly when connected to a port. You can carry it without adding significant bulk to your gear.
Durability is a key part of the design. According to the listing, the drive offers IP68 dust and water resistance. It also provides 4000lb crush resistance and up to 3m drop protection. These ratings suggest it can survive accidental spills or rough handling in the field. The dual-mode compatibility with Thunderbolt 3 and USB-C means you can use it with various host devices. This flexibility ensures the drive remains useful even if you switch between different computers.
Setup and everyday use
You plug the drive into your computer using the included cable. The listing states it comes pre-formatted in exFAT. This means you can use it immediately on Windows and macOS without needing to reformat or install extra software. You do not need to wait for drivers or run complex setup utilities. The device is ready to go.
It offers dual-mode compatibility. You can connect via Thunderbolt 3 for speeds up to 40Gbps. This delivers the maximum read speed of 3000MB/s. You can also use the USB-C port for 10Gbps connections. This ensures it works with Intel EVO laptops and desktops that may not have Thunderbolt ports. You get flexibility depending on your computer's available ports.
Daily use is straightforward. The aluminum core helps pull heat away from the internal drive. This thermal management helps maintain those fast transfer speeds during long work sessions. You can move large video projects or backups without the drive slowing down due to heat.
The rugged design supports everyday handling. It has IP68 dust and water resistance. You can use it in dusty or wet environments without worry. It also offers 4000lb crush resistance and up to 3m drop protection. You can toss it in a bag or drop it on a hard floor. The drive is built to survive rough handling while you work.
Before You Buy This Drive
You need a host device with a Thunderbolt 3 port to reach the listed 3000MB/s read speeds. If your computer only offers USB-C 10Gbps, transfer rates will drop significantly. Verify your laptop or desktop supports Thunderbolt 3 before purchasing. The drive comes pre-formatted in exFAT, so it works immediately on Windows and macOS without extra setup. You do not need to install drivers or reformat the drive for basic use. Keep the aluminum core clear of obstructions to ensure proper heat dissipation. Dust and debris can block the cooling paths. The rugged design handles drops up to 3 meters and offers IP68 water resistance. This makes it suitable for field work. However, it sits apart from internal NVMe and SATA SSDs. You must budget for a compatible Thunderbolt cable if one is not included. Check your port availability first.
Check before you buy
- Verify your computer has a Thunderbolt 3 port for max speeds.
- Confirm exFAT format works with your current operating system.
- Ensure you have space for the 4.36 inch external unit.
- Check if your existing cables support Thunderbolt 3 data transfer.
