Fast NVMe speed or NAS-grade HDD capacity: which should you buy?

Display

There is no display or screen quality to compare here, so this category is not relevant. For storage buyers, the equivalent consideration is how the drive affects system responsiveness and workload feel. Winner: TEAMGROUP MP44, because its NVMe interface delivers far quicker access times and a more immediate user experience than a mechanical HDD.

Performance

This is where the products diverge sharply. The TEAMGROUP MP44 is rated up to 7200 MB/s read and 6200 MB/s write over PCIe 4.0 x4, which is excellent for OS boot drives, application loading, VM storage, scratch space, and fast game libraries. The WD Red Plus WD40EFZX is a SATA 6Gb/s 3.5-inch hard drive, so even under ideal conditions it is limited by the SATA interface and mechanical platters; in practice it is dramatically slower for random access and small-file workloads, though it can still deliver decent sequential throughput for bulk media storage. Winner: TEAMGROUP MP44 by a wide margin for raw speed, latency, and responsiveness.

Build quality and design

The TEAMGROUP MP44 is an M.2 2280 SSD, meaning it is compact, cable-free, and ideal for modern motherboards, laptops, NUCs, and small-form-factor builds. It also suits systems with limited drive bays, which is particularly useful in compact NAS units or mini PCs that support NVMe storage. The WD Red Plus is a traditional 3.5-inch HDD, which requires a SATA data cable and power connection, plus a physical drive bay; in return, it is built for NAS use and is generally better suited to multi-drive enclosures where capacity and endurance matter more than speed. Winner: tie, because the MP44 wins on compactness and simplicity, while the WD wins on traditional NAS fit and physical integration into larger storage arrays.

Battery life

If you are using a laptop, the TEAMGROUP MP44 is the better choice because SSDs are far more power-efficient than spinning hard drives and generate less heat and vibration. That can translate into better battery life, quieter operation, and less thermal stress in slim devices. The WD Red Plus is not a realistic choice for battery-powered systems and is intended for always-on desktop or NAS hardware. Winner: TEAMGROUP MP44.

Price and value for money

On price alone, the TEAMGROUP MP44 is £183.95, while the WD Red Plus WD40EFZX is £198.98, making the SSD £15.03 cheaper despite being the faster product. That is strong value if your priority is performance, especially since the MP44 also has a much higher review count at 11,025 reviews and a 4.7/5 rating, compared with 2,737 reviews and 4.4/5 for the WD drive. However, price-to-capacity is where the WD Red Plus can still make sense, because 4TB of NAS-grade HDD storage is often cheaper per gigabyte than high-end NVMe SSDs in broader market terms, even if that is not reflected in this specific listing. Winner: TEAMGROUP MP44 for this exact comparison, because it is cheaper and significantly faster.

Game library/features

If you are installing games, the TEAMGROUP MP44 is the clear winner. Modern game libraries benefit from fast load times, quick patching, and better responsiveness in open-world titles and asset-heavy engines, all of which favour NVMe storage. The WD Red Plus is fine for archiving a game library or storing media, but it will not provide the same snappy experience when launching or streaming assets. Winner: TEAMGROUP MP44.

Overall user experience

The MP44 feels like an upgrade you notice immediately: faster boot, quicker app launches, less waiting, and no moving parts. It is also easier to install in compatible systems because it slides into an M.2 slot without cables, which is ideal for laptops, desktops, NUCs, and many newer NAS appliances with NVMe support. The WD Red Plus offers a different kind of experience: quieter than some consumer hard drives under light use, very suitable for bulk storage, and designed around NAS reliability rather than speed. But for most users searching these exact products, the SSD provides the better day-to-day experience unless they specifically need large, inexpensive capacity for a NAS array. Winner: TEAMGROUP MP44.

Overall summary: the TEAMGROUP MP44 is the better buy for most people because it is faster, cheaper, more power-efficient, and more versatile across laptops, desktops, and compact systems. The WD Red Plus is only the better choice if your priority is 4TB of NAS-oriented spinning storage for media, backups, or a multi-bay RAID/NAS setup where capacity and drive-bay compatibility matter more than speed.
