Team Group 4TB SSD PCIe 4.0 x4 NVMe M.2 2280

The Team Group T-FORCE CARDEA A440 delivers 4TB of PCIe 4.0 storage with 7000 MB/s reads and a 3000 TBW endurance rating. It's priced lower than comparable drives from SanDisk and Samsung, making it a strong value for gamers and editors. The 3-year warranty and a single reported early failure are the main caveats. If you want max capacity and speed without paying flagship prices, this is a solid pick.

The headline numbers are 7000 MB/s sequential read and 6900 MB/s write. That's essentially the ceiling for PCIe 4.0, and in our database this drive lands in the top tier for speed. Real-world translation: loading a 100GB game folder or scrubbing through 8K footage feels instant. The random read and write IOPS both hit 1000K, which puts it among the best on the market for the kind of small-file operations that make everyday use feel snappy.

But PCIe 4.0 drives at this level have a caveat. The difference between 6500 MB/s and 7000 MB/s is basically invisible outside of synthetic benchmarks. What you're really paying for here is the combination of speed, capacity, and endurance. The 3000 TBW rating is a standout, meaning you could write over 1.6TB every single day for five years before hitting the rated limit. For video editors and heavy gamers, that's real peace of mind.

The SanDisk Black SN850X is the most direct competitor here. It's been a favorite for years, with similar sequential speeds and a 5-year warranty. The SN850X tends to cost more at 4TB, and its endurance rating is lower than the CARDEA A440's 3000 TBW. If you want the safety net of a longer warranty and a more established brand, the SanDisk is the safer pick. But you'll pay for it.

The Samsung 9100 PRO is a different beast entirely. It's a PCIe 5.0 drive, so it's dramatically faster on paper, but you need a motherboard that supports Gen 5 to take advantage of it. And the price premium is substantial. The Kingston FURY Renegade G5 and Crucial T700 are also in the Gen 4 space, with the Kingston offering a similar speed profile and the Crucial pushing slightly higher sequential numbers. The Micron T710 is another solid option, but it's harder to find at retail. For most people, the real choice comes down to the CARDEA A440 versus the SN850X, and it's a question of warranty versus upfront savings.

The CARDEA A440 sits in a weird spot on the value curve. At 530 to 570 USD for 4TB, it's not cheap. In fact, our data puts it near the bottom for affordability, which makes sense given the capacity and performance tier. But when you compare it against the SanDisk Black SN850X or Samsung 9100 PRO at similar capacities, the Team Group drive often undercuts them by a meaningful margin while delivering nearly identical real-world performance.

That's the trade-off. You're giving up brand recognition, a longer warranty, and some polish in exchange for saving cash upfront. For a workstation build where the drive is going to be hammered daily, the 3-year warranty might give you pause. For a gaming rig or a secondary editing machine, the math works out in Team Group's favor.

The Team Group T-FORCE CARDEA A440 is one of those drives that makes you wonder why you'd spend more on a flagship from the big names. You get 4TB of PCIe 4.0 storage, a DRAM cache, and sequential speeds that basically max out what the interface can do. On paper, it's a workstation and gaming workhorse that doesn't ask for much in return beyond a free M.2 slot and a motherboard that can handle Gen 4.

Who's this for? If you're juggling massive video projects, a Steam library that's somehow ballooned past 2TB, or you just want a single drive that can hold everything without breaking a sweat, this is aimed squarely at you. The 4TB capacity alone puts it in the top tier of what most people will ever need, and the endurance rating means you won't be nervously checking SMART data every few months.

What makes it interesting is the price-to-performance story. Team Group isn't a household name like Samsung or Western Digital, but the CARDEA A440 goes toe-to-toe with drives that cost noticeably more. The catch? A 3-year warranty and some mixed chatter about long-term reliability. We'll dig into that.

If you're putting this in a laptop or an external enclosure, look elsewhere. The portable score in our database is near the bottom, and the drive's power draw and thermals aren't optimized for tight spaces. A lower-power drive like the Samsung 9100 PRO or a purpose-built portable SSD would serve you better.

Also skip this if you're building a system where uptime is critical and you can't afford a failure. The 3-year warranty and that one early death report are red flags for a production machine. Spend the extra money on a SanDisk SN850X or Samsung drive with a 5-year warranty and a longer track record. The peace of mind is worth the premium when your income depends on the drive working every single day.

If you're building a gaming PC and want a single 4TB drive that can hold your entire library with room to spare, the CARDEA A440 is an easy recommendation. The speed is there, the endurance is excellent, and the price undercuts the big names. You'll notice zero difference in load times compared to a drive that costs 100 USD more.

For a professional workstation where downtime means lost income, I'd think twice. The 3-year warranty and that one report of a drive dying after six weeks are enough to make me lean toward the SanDisk SN850X or Samsung's offerings if you can stomach the price. The CARDEA A440 is a great drive, but it's a better fit for enthusiasts and gamers than for mission-critical work.
