6 Best Alternatives to the Western Digital 256GB M.2 2230 PCIe (2026)

How each alternative compares

KIOXIA BG4 256GB M.2 2230 NVMe SSD

The Kioxia BG4 shares the same M.2 2230 form factor and PCIe 3.0 interface as the Western Digital drive, making it a direct physical replacement for Steam Deck and Surface Pro users. It offers a slightly lower sequential read speed of 2200 MB/s compared to the WD’s 2400 MB/s, while write speeds remain unspecified in the provided data. The physical dimensions are nearly identical, with a width of 0.9 inches versus the WD’s 0.86 inches. You should choose this if you find it available at a lower price point, as it provides adequate performance for everyday tasks in handheld consoles without sacrificing the compact footprint required by your device.

XPG SX6000 Lite 512GB NVMe SSD

The XPG SX6000 Lite differs significantly in form factor, using the standard M.2 2280 size instead of the compact 2230 layout. It offers double the storage capacity at 512GB compared to the WD’s 256GB, which suits users upgrading laptops with standard slots. The interface remains PCIe 3.0, but the physical length is 3.15 inches, far exceeding the WD’s 1.18 inches. This drive is not suitable for handheld consoles or tablets requiring the smaller size. You should pick this option if your device accepts standard M.2 2280 drives and you need more space for files and applications, accepting the larger physical footprint in exchange for increased storage volume.

SK Hynix 512GB PCIe 3.0 NVMe SSD

The SK Hynix drive uses the standard M.2 2280 form factor, making it incompatible with devices requiring the smaller 2230 size like the Steam Deck. It provides 512GB of storage, doubling the capacity of the Western Digital 256GB model. The interface is PCIe 3.0, similar to the original, but the physical dimensions are much larger at 3.15 inches in length. This SSD is designed for standard desktops and laptops where space is less constrained. You should select this alternative if you are upgrading a traditional computer rather than a handheld console, prioritizing higher storage capacity and standard compatibility over the compact size offered by the original WD drive.

TEAMGROUP MP33 512GB PCIe 3.0 M.2 SSD

The TEAMGROUP MP33 utilizes the standard M.2 2280 form factor, meaning it will not fit in devices requiring the compact 2230 size. It offers 512GB of storage, which is double the capacity of the Western Digital 256GB drive. The interface is PCIe 3.0, matching the original, but the physical length is 3.15 inches. It features SLC cache technology and TLC NAND, which may impact sustained write performance differently than the WD model. You should choose this if your system accepts standard M.2 2280 slots and you need more storage space. It is a practical upgrade for desktops and laptops where the smaller form factor is not a requirement.

PNY CS1030 500GB PCIe 3.0 M.2 SSD

The PNY CS1030 uses the standard M.2 2280 form factor, so it is not compatible with handheld consoles or tablets needing the 2230 size. It provides 500GB of storage, significantly more than the WD’s 256GB. The interface is PCIe 3.0, similar to the original, but the physical dimensions are larger at 3.1 inches in length. This drive is intended for desktops and laptops that accept standard M.2 drives. You should pick this option if you are upgrading a standard computer and need double the storage capacity of the original drive, accepting the larger physical size in exchange for increased storage volume and standard compatibility.

Addlink S70 Lite 512GB PCIe Gen3 M.2 SSD

The Addlink S70 Lite uses the standard M.2 2280 form factor, making it unsuitable for devices requiring the compact 2230 size. It offers 512GB of storage, double the capacity of the Western Digital 256GB model. The interface is PCIe Gen3, matching the original, but the physical length is 3.2 inches. It is designed for standard desktop and laptop gaming builds where space is less constrained. You should choose this alternative if your system accepts standard M.2 2280 slots and you need more storage for games and applications. It provides a practical upgrade for users who prioritize capacity and standard compatibility over the compact footprint of the original drive.
