PCIe 5.0 vs Portable USB
interface speed
The KIOXIA Exceria G3 uses a PCIe 5.0 Gen5 x4 interface. This internal connection supports very high bandwidth, enabling random read speeds up to 1,600,000 IOPS and random write speeds up to 1,450,000 IOPS. These metrics indicate rapid system responsiveness and fast load times for heavy workloads. In contrast, the KIOXIA EXCERIA PLUS G2 Portable SSD relies on a USB 3.2 Gen 2 connection. Its maximum sequential read speed is 1,050MB/s, with a write speed of 1,000MB/s. While sufficient for external transfers, these numbers are significantly lower than the internal PCIe 5.0 capabilities. The Exceria G3 offers superior throughput for internal system tasks.
form factor
Storage form factor determines where and how you install the drive. The KIOXIA Exceria G3 is an internal M.2 2280 drive. It measures 3.19 inches in length, 0.87 inches in width, and 0.09 inches in height. This compact profile is designed to fit directly onto motherboard slots in desktops and laptops. The KIOXIA EXCERIA PLUS G2 is a portable external drive. It has dimensions of 2.83 inches in length, 1.57 inches in height, and 0.46 inches in width. It weighs 1.48 ounces and features an aluminum casing. The portable unit is built for mobility, while the internal drive is built for permanent installation.
compatibility
Device compatibility varies significantly between these two models. The KIOXIA Exceria G3 is designed for internal use, primarily targeting gaming PCs and systems that support PCIe 5.0. Its compatibility is listed specifically for gaming applications. The KIOXIA EXCERIA PLUS G2 Portable SSD offers broader external compatibility. It supports Windows OS, macOS, iPadOS, iOS, and Android OS. It also works with gaming consoles including the PS4, PS4 Pro, PS5, and Xbox Series X/S. The portable drive allows you to use the same storage across multiple device types, whereas the internal drive is restricted to compatible internal slots.
data security
Security features are not equal between these two products. The KIOXIA EXCERIA PLUS G2 Portable SSD includes built-in data security measures. It supports password protection and 256-bit AES hardware encryption to safeguard your files. It also allows the use of KIOXIA’s SSD Utility software for monitoring health and lifespan. The product data for the KIOXIA Exceria G3 does not mention any hardware encryption or password protection features. For users who need to secure data on the go, the portable drive provides essential encryption tools that the internal drive does not list.
thermal design
Heat management is handled differently by each drive. The KIOXIA EXCERIA PLUS G2 Portable SSD features a durable aluminum casing. This design improves heat dissipation to maintain stable performance during heavy workloads. The metal housing helps manage thermal output for an external device. The KIOXIA Exceria G3 is an internal M.2 drive. The provided specifications do not list any specific cooling solution, such as a heatsink or thermal pad, for this model. Internal drives often rely on system airflow or motherboard heatsinks. Without listed thermal data for the internal drive, the portable drive has a documented cooling advantage.
Choose the right KIOXIA drive for you
Desktop PC builders seeking maximum speed
