Our Take

Best for: QNAP NAS owners who need to add fast SSD storage or caching.

The QNAP QM2-4P-384 is a straightforward tool for adding serious solid-state storage. Its main job is to turn one PCIe slot into four dedicated M.2 NVMe slots. This is a clear choice for QNAP NAS owners who have used up their built-in drive bays but still want the speed and responsiveness of SSDs for applications or caching. It is also a viable option for PC builders looking to add multiple M.2 drives without relying on the motherboard, though its primary design is for NAS systems.

What stands out is the included hardware. You get both a low-profile and a full-height bracket in the box, which is a thoughtful touch that ensures compatibility with a wider range of cases and NAS units right out of the gate. The card itself is simple, requiring no external power, and it supports the common 2280 form factor for M.2 drives.

The limitation is that it is just an adapter. It does not include any SSDs, so the total cost will be significantly higher once you add four quality NVMe drives. It also does not create a RAID array on its own; that management is handled by your NAS or computer's operating system. At this sale price, it is a very cost-effective way to a lot of fast storage potential if your system supports it.

Price Analysis

At $189, this card is priced well below its recent 30 and 90-day average of $267.82. While the 180-day average was lower at $220.78, the current price represents a solid 29% discount from the recent norm. This is a good time to buy if you have been waiting for a price drop, as it is notably cheaper than it has been for the past three months.

Common Questions

Does this work with any PC or just QNAP NAS?

It is designed for and tested with QNAP NAS systems, but it uses a standard PCIe interface. It may work in a desktop PC if the motherboard and operating system support it, but compatibility is not guaranteed.

What kind of M.2 SSDs does it support?

It supports M.2 2280 form factor NVMe PCIe Gen3 x4 SSDs. It does not support SATA-based M.2 drives or the older AHCI protocol.

Do I need a special driver for this card?

For use in a QNAP NAS, the necessary drivers are typically built into the QTS or QuTS hero operating system. For use in a Windows PC, standard NVMe drivers should work.
