Know before you buy
While this drive is physically compatible with most M.2 slots, the 2230 form factor is much shorter than the standard 2280 size found in most desktop motherboards. You will likely need a mounting bracket or adapter to secure it properly in a full-sized slot.
Yes, this drive is well-suited for use as a boot drive. Its NVMe interface and BiCS FLASH technology provide the fast read speeds necessary for quick system startup and responsive application loading.
Yes, this drive is backward compatible with PCIe Gen2 interfaces. However, keep in mind that your data transfer speeds will be limited by the older generation's bandwidth capabilities.
The 2230 form factor is designed specifically for space-constrained devices like ultra-mobile PCs, handheld gaming consoles, and compact IoT hardware. Its small footprint allows for high-performance storage in systems where a standard-sized SSD would not fit.
No, this is a standard NVMe SSD that uses the native drivers built into modern operating systems like Windows 10 and 11. It should be recognized automatically by your BIOS and OS upon installation.
