User Manual
FAQ
What types of M.2 drives does this controller card support?
The PEX2M2 supports M.2 SATA SSDs with B-Key interfaces. It is compatible with drives measuring 22110, 2280, 2260, 2242, and 2230 millimeters in length. The card includes adjustable stand-offs and multiple mounting holes to accommodate these five standard form factors. This broad compatibility ensures support for most current and future M.2 SATA solid-state drives available on the market.
What power connection does this PCIe card require?
The card offers dual power options. It can operate using only PCIe bus power from the slot itself, which is sufficient for most M.2 SATA SSD configurations. For additional power stability or when using drives with higher power requirements, the card includes a 4-pin floppy power connector that can be connected to your computer's power supply. This flexibility ensures reliable operation across various drive combinations and system configurations.
Will this controller work in a small form-factor computer case?
Yes, the card includes both a standard full-profile bracket and a half-height/low-profile bracket specifically for installation in small form-factor computers. The low-profile bracket replaces the full-profile bracket during installation, allowing the card to fit in compact cases with limited vertical clearance. The card's standard PCIe dimensions and dual bracket inclusion make it suitable for both traditional desktop towers and space-constrained small form-factor systems.
What PCIe slots are compatible with this controller card?
The PEX2M2 is compatible with PCI Express x4, x8, and x16 slots. The card physically fits into any of these slot sizes while electrically operating as a PCIe 2.0 device. This broad slot compatibility ensures the card will work with virtually any desktop motherboard that has an available PCIe slot, regardless of whether it's a shorter x4 slot or a full-length x16 slot typically used for graphics cards.
Does this controller require special drivers for operation?
No special drivers are required for basic operation. The card uses native operating system support available in Windows, Linux, and other modern operating systems. This plug-and-play functionality means the card is typically detected automatically when installed, with the operating system handling driver installation through its standard hardware recognition processes. For advanced features or specific configurations, you may consult the included documentation, but day-to-day operation requires no additional driver installation.
What connectivity or interface options are available?
Connectivity details help confirm how StarTech.com 2x M.2 SATA SSD Controller Card - PCIe - PCI Express M.2 SATA III Controller - NGFF Card Adapter - Add two Next Form M.2 (PEX2M2) can integrate with your network, accessories, and surrounding peripherals before rollout or replacement planning.
