StarTech.com Dual M.2 PCIe SSD Adapter Card, PCIe x8 / x16 to Dual NVMe or AHCI M.2 SSDs, PCI Express 4.0, 7.8GBps/Drive, Bifurcation Required - Windows/Linux Compatible

Product Overview

AI-generated summary

At £59.28 ex-VAT, this is a decent “get two NVMe drives on one slot” workaround, but it’s not the sort of thing I’d buy unless you actually understand your server/desktop’s PCIe bifurcation support. These StarTech dual-adapter cards live or die on whether your motherboard will split the lanes the way the card expects. If bifurcation isn’t enabled (or isn’t supported), you can end up with one drive not training properly, flaky detection, or wasted slots—annoying for something that’s otherwise simple.

Who should buy it: businesses repurposing hardware where you’ve got spare PCIe bandwidth but only one M.2 slot, or teams building small storage expansions for lab/test machines under Windows or Linux. It’s also a sensible choice if you’re comfortable managing BIOS settings and want value over branded, integrated storage platforms. Who shouldn’t: anyone trying to “plug and play” dual M.2 without checking the exact bifurcation/slot wiring on their chassis—especially if they need reliability for production workloads. If you don’t know your platform will cooperate, I’d spend a bit more (or choose a different approach) rather than troubleshoot PCIe lane training issues.
