SanDisk Professional 12TB G-Drive Project SSD Alternatives: 6 Similar Picks Compared

How each alternative compares

Apricorn Aegis Fortress L3 2TB Encrypted SSD

The Apricorn Aegis Fortress L3 2TB Encrypted SSD prioritizes security over raw capacity. It uses a USB 3.0 interface and measures 3 by 4.75 by 0.6 inches. At 4.16 ounces, it is far more portable than the 8.64-ounce SanDisk bundle. You give up the 12TB HDD and the Thunderbolt 3 speed for certified encryption. This drive suits professionals who handle small files and need data protection rather than large archives. The compact aluminum chassis fits easily in a bag. If your workflow involves sensitive documents and you do not need terabytes of space, this secure option is a logical swap for the larger SanDisk unit.

WD 24TB My Book Duo Dual-Drive Desktop RAID

The WD 24TB My Book Duo offers double the storage of the SanDisk 12TB drive. It is a desktop RAID unit with a USB interface, making it stationary rather than portable. The dimensions are 3.94 by 6.3 by 7.09 inches. It lacks the Thunderbolt 3 port and the included PRO-BLADE SSD slot found in the original bundle. You gain significant capacity for large media libraries but lose the ability to easily move data between locations. This drive is ideal for users who manage massive video archives on a single workstation. It provides robust data integrity for stationary storage needs without the complexity of managing two separate devices.

G-Technology 18TB G-DRIVE Desktop

The G-Technology 18TB G-DRIVE Desktop provides more storage than the 12TB SanDisk bundle. It connects via USB 3.0 and features a durable aluminum chassis. The drive measures 5.06 by 7.72 by 1.39 inches. It lacks the Thunderbolt 3 interface and the secondary SSD slot included with the original product. You get a single high-capacity drive for desktop use but sacrifice the fast offloading capability of the PRO-BLADE slot. This option fits users who prioritize raw storage space and build quality over advanced features. It is a straightforward solution for expanding desktop storage without the need for portable, high-speed transfer workflows.

Seagate Expansion 18TB Desktop External Hard Drive

The Seagate Expansion 18TB Desktop Hard Drive matches the G-Technology in capacity but differs in design. It uses a USB 3.0 interface and measures 8.35 by 3.03 by 8.58 inches. It weighs 3.03 pounds, making it heavier and less portable than the SanDisk bundle. This drive lacks the Thunderbolt 3 port and the PRO-BLADE SSD slot entirely. It is designed for simple, large-scale backups or archives on a desktop. You trade the speed and dual-device convenience of the SanDisk unit for a straightforward, high-capacity storage solution. It suits users who need maximum space for static data without requiring fast transfer speeds or portable form factors.

SanDisk Professional 18TB G-DRIVE PRO

The SanDisk Professional 18TB G-DRIVE PRO offers 50% more storage than the 12TB bundle. It features a 7200 RPM rotational speed and supports both Thunderbolt and USB-C interfaces. The drive measures 5.12 by 8.27 by 1.81 inches and weighs 2.6 pounds. It lacks the PRO-BLADE SSD slot found in the original bundle. You gain a larger single drive with flexible connectivity options but lose the dedicated fast-offloading slot. This drive is best for desktop users who need high capacity and enterprise-grade reliability. It suits professionals who prioritize interface flexibility and storage volume over the specialized dual-device workflow of the Project SSD bundle.

ClevX SecureDrive KP Encrypted External Drive

The ClevX SecureDrive KP 2TB SSD focuses on encryption and portability. It uses a USB 3.0 interface and weighs 9 ounces. The drive is compatible with Mac systems. It lacks the massive 12TB capacity and the Thunderbolt 3 speed of the SanDisk bundle. You give up the HDD storage and the PRO-BLADE SSD slot for strong security features in a compact form. This drive suits users who need encrypted storage for sensitive data on the go. It is a specialized tool for security-conscious professionals who do not require the large archives or high-speed transfer capabilities of the larger SanDisk Project SSD bundle.
