StarTech.com 2x M.2 SATA SSD Controller Card - PCIe

Product Overview

AI-generated summary

At ~£22 ex-VAT, this kind of “2x M.2 SATA SSD controller on a PCIe card” is mostly for one thing: squeezing extra SATA SSD capacity into a desktop or older system that doesn’t have the right native M.2 SATA slots. If you’ve got free PCIe bandwidth and you’re trying to repurpose a couple of M.2 SATA drives (not NVMe), it can be a cheap, practical upgrade. The appeal is value-for-money: you get more storage options without buying a new board or whole storage kit.

That said, I wouldn’t buy it as a general-purpose storage solution. You need to be sure your M.2 sticks are actually SATA (not NVMe), and you should expect some quirks: performance won’t be “PCIe fast”, and compatibility can vary across motherboards/BIOSes. It’s also not ideal if you care about sustained performance under load or you want a super-straightforward boot/storage configuration—these cards can be finicky compared to native M.2 support.

**Who should buy:** IT-adjacent users in small offices/labs who want to expand SATA SSD capacity cheaply in a desktop with spare PCIe slots, and who already have (or can buy) M.2 SATA drives. **Who shouldn’t:** anyone trying to add speed for virtualization, heavy concurrent workloads, or anyone who might accidentally buy NVMe drives for a SATA controller. If you tell me your motherboard model and whether your SSDs are SATA or NVMe, I can sanity-check whether this is a safe bet.
