KIOXIA vs Micron SSD Specs
interface generation
The KIOXIA Exceria G3 uses a PCIe 5.0 Gen5 x4 interface, offering significantly higher bandwidth potential than the Micron 2450 Series. The Micron drive relies on a PCIe 4.0 Gen4 x4 connection, which is backward compatible with PCIe Gen3 slots. While PCIe 5.0 allows for faster data transfer rates in theory, you need a compatible motherboard to utilize the extra speed. The Micron drive works in older systems that lack PCIe 5.0 support. For users with current high-end platforms, the KIOXIA interface provides future-proofing. However, the Micron standard remains robust for most current desktop and laptop needs.
physical form factor
Physical dimensions dictate where you can install these drives. The KIOXIA Exceria G3 follows the standard M.2 2280 form factor, measuring 3.19 inches in length. This is the most common size for desktop motherboards and many laptops. The Micron 2450 Series uses the smaller M.2 2230 format, measuring just 1.18 inches in length. This compact size is essential for devices like the Steam Deck, Surface Pro, and certain laptops with limited internal space. If you are building a standard desktop PC, the KIOXIA size fits most slots. For handhelds or thin ultrabooks, the Micron drive is the only viable option due to its shorter footprint.
sequential transfer speed
Sequential speeds affect large file transfers, such as moving video projects or installing games. The Micron 2450 Series lists sequential read speeds up to 3500 MB/s and write speeds up to 3000 MB/s. The KIOXIA Exceria G3 does not publish specific sequential MB/s figures in the provided data. It highlights random IOPS instead, with up to 1,600,000 random read and 1,450,000 random write operations. Without explicit sequential speed data for the KIOXIA drive, a direct comparison of raw throughput is not possible based on the available specifications. You may need to check the manufacturer's full datasheet for exact MB/s numbers for the KIOXIA model.
nand flash type
The underlying memory technology impacts density and potential endurance. The KIOXIA Exceria G3 is built with advanced BiCS Flash 3D QLC NAND. QLC NAND stores four bits per cell, allowing for higher storage densities in a compact package, which helps keep costs down for larger capacities. The Micron 2450 Series does not specify its NAND type in the provided data. It is likely TLC or a similar variant, but without explicit confirmation, we cannot compare cell architectures directly. The KIOXIA drive’s use of QLC suggests a focus on high-capacity storage efficiency. If you prioritize density and cost-per-gigabyte, this specification favors the KIOXIA approach.
system compatibility
Compatibility determines which devices can use the drive. The Micron 2450 Series is explicitly listed as compatible with Surface Pro tablets, Steam Deck, and other systems requiring an M.2 2230 slot. It also supports PS5, laptops, and desktops. The KIOXIA Exceria G3 is marketed for gaming and PC use, fitting the standard M.2 2280 slot found in most modern desktops and laptops. The Micron drive offers broader versatility for handheld gaming consoles and compact tablets. The KIOXIA drive is better suited for traditional desktop builds and standard laptops. Choose Micron for specialized hardware like the Steam Deck, and KIOXIA for standard PC upgrades.
Which NVMe SSD fits your needs
Users with M.2 2230 slots
The Micron 2450 Series uses the M.2 2230 form factor, measuring just 1.18 inches in length. This compact size fits devices like the Steam Deck, Surface tablets, and select laptops. The KIOXIA drive is a standard 2280 size, which is too large for these specific slots. You need the smaller drive for compatibility.
PS5 owners needing expansion
The Micron drive is explicitly listed as compatible with the PS5. It offers sequential read speeds up to 3500 MB/s, which meets the console requirements for fast game loading. The KIOXIA Exceria G3 is a 2280 drive, which does not fit the PS5 expansion slot. Choose the Micron for your console upgrade.
Desktop users seeking speed
The KIOXIA Exceria G3 uses a PCIe 5.0 interface, providing higher theoretical bandwidth than the Micron’s PCIe 4.0 connection. It also boasts random read speeds up to 1,600,000 IOPS. These specs benefit desktop PCs and gaming rigs where maximum throughput and responsiveness are priorities. The larger 2280 size fits standard desktop motherboards.
