Select the WD Green SN350 if you are building or upgrading a system that requires fast internal NVMe performance. The right choice depends entirely on whether you prioritize mobility or raw speed.
Speed, Form Factor, and Portability
Transfer speed
The WD Green SN350 offers significantly higher sequential read speeds. It reaches up to 3,200 MB/s, which is ideal for loading large files quickly on compatible systems. The My Passport Go is limited to 300 MB/s. This lower speed reflects its role as a portable drive rather than a high-performance internal component. You will notice a major difference in how fast data moves between the drives. If speed is your priority, the SN350 is the clear choice for daily computing tasks.
Form factor
These drives use completely different physical designs. The SN350 is an M.2 2280 internal SSD. It is a small, flat stick that plugs directly into a motherboard. The My Passport Go is a portable external drive. It measures 3.7 by 2.6 inches and includes an integrated cable. You cannot install the My Passport Go inside a computer case. You must use it via USB. The SN350 requires an available M.2 slot. The My Passport Go requires a USB port. Your hardware determines which form factor works for you.
Interface
The connection type defines how each drive communicates with your system. The SN350 uses a Gen3 PCIe NVMe interface. This provides high bandwidth for internal storage needs. The My Passport Go connects via USB. It acts as an external storage device. You cannot plug the SN350 into a USB port directly without an adapter. The My Passport Go is designed for plug-and-play use with PCs, Macs, and consoles like PS4 and Xbox One. The interface choice depends on whether you are building a PC or adding portable storage.
Build and durability
Both drives are solid-state, meaning they have no moving parts. The My Passport Go features rubber edges and is drop-resistant up to 2 meters. This design protects it during travel. The SN350 is also shock-resistant against accidental bumps. However, it lacks the ruggedized external casing of the My Passport Go. The SN350 is meant to be installed inside a computer. The My Passport Go is built to be carried in a bag. Both offer reliable dependability for their intended uses.
NAND type
The SN350 uses QLC NAND flash memory. This type offers high capacity at a lower cost per gigabyte. The My Passport Go does not list its specific NAND type in the provided data. QLC drives are suitable for everyday computing and gaming. They may have different endurance characteristics compared to other types. Since the My Passport Go specifications do not detail the NAND technology, we cannot compare this aspect directly. The SN350 provides this specific technical detail for informed purchasing decisions.
Choose the right drive for your needs
Gamers needing portable storage for consoles
You should choose the My Passport Go if you need to expand storage for a PS4 or Xbox One. Its integrated cable and pocket-sized design make it easy to carry. The drive is drop-resistant up to two meters and works seamlessly with both Windows and Mac computers for backup or Time Machine support.
Users building or upgrading desktop PCs
Pick the WD Green SN350 if you are installing an internal drive. Its M.2 2280 form factor fits directly into motherboards with NVMe slots. You get fast Gen3 PCIe speeds up to 3,200 MB/s for quick file transfers. The included SSD Dashboard lets you monitor drive health and usage from your desktop.
People wanting fast internal system performance
Choose the WD Green SN350 for faster daily computing. The NVMe interface delivers significantly higher sequential read speeds than the portable option. This QLC NAND drive is shock-resistant and ideal for business or personal use where loading large files quickly matters. It offers a substantial performance boost for internal system tasks.
