Interface, Speed, and Form Factor
Transfer speed
Western Digital My Passport 256GB Portable SSD offers sequential read speeds up to 540 MB/s. This is a solid speed for an external USB drive. In contrast, the Western Digital 256GB M.2 2230 PCIe 3.0 SSD delivers significantly higher performance. It provides sequential read speeds up to 2400 MB/s and write speeds up to 950 MB/s. The M.2 drive is nearly five times faster in reading data. If you need rapid file transfers, the internal M.2 option is the clear winner. The portable drive is adequate for general backup tasks.
Interface type
The My Passport uses a USB 3.1 Gen 2 interface. It supports USB Type-C and is compatible with USB 3.0, USB 2.0, and USB-A ports. This makes it easy to connect to various computers and laptops. The M.2 2230 drive uses a PCIe Gen3 x4 interface. It connects directly to an M.2 slot on a motherboard or compatible device. You cannot plug it into a USB port. The USB interface offers broader compatibility with standard computers. The PCIe interface offers higher bandwidth but requires specific hardware support.
Form factor
The My Passport is an external portable drive. It measures 3.5 inches in length, 1.8 inches in width, and 0.39 inches in height. It weighs 1.44 ounces. This size is designed for portability and easy storage in a bag. The M.2 2230 drive is much smaller. It measures 1.18 inches in length, 0.86 inches in width, and 0.1 inches in height. It is a compact internal drive. The M.2 form factor is ideal for tight spaces like tablets or handheld consoles. The portable drive is better for moving data between different machines.
Compatibility
The My Passport SSD works with any device that has a USB port. It includes WD Discovery software for backup and security. The M.2 2230 drive is compatible with systems featuring an M.2 2230 NVMe PCIe slot. Specific examples include the Surface Pro Tablet and Steam Deck. It is not a universal drive. You must check if your device has the correct slot. The portable drive is universally compatible with USB. The internal drive is specialized for specific modern devices. Choose based on your hardware capabilities.
Security features
The My Passport SSD includes hardware encryption and password protection. It also features WD Security software for added data safety. These features help protect your files if the drive is lost or stolen. The specifications for the M.2 2230 drive do not list built-in hardware encryption or password protection. It relies on the host system for security. If data protection is a priority, the My Passport offers dedicated security tools. The M.2 drive is a bare storage component without these features.
