Team Group’s T-Force Cardea Zero Z340 SSD isn’t much more expensive than most entry-level M.2 SSDs, but with the latest mainstream hardware powering it, it’s a good choice for gamers looking to stretch their budget a bit for something more consistent and reliable.


  • Competitive pricing, performance & efficiency
  • Single-sided form factor
  • 5-year warranty & class-leading endurance ratings
  • Graphene & copper heat spreader


  • Blue PCB
  • Heat spreader is very malleable

Team Group’s T-Force Cardea Zero Z340 is a mainstream M.2 NVMe SSD comprised of one of the most untraditional hardware pairings we’ve ever tested in an SSD before. It also brings a unique and ultra-thin heat spreader made up of graphene and copper, which keeps the drive cool even in the least-optimal environments. The Cardea Zero Z340 is well worth a look, especially considering its competitive pricing.

With Micron’s 96L flash more readily available, Team Group has seized the opportunity to create a rather untraditional hardware combination to power the company’s Cardea Zero Z340. Traditionally, we’ve seen SM2262EN-based SSDs feature Micron’s flash, while Phison’s E12 has usually been paired with Kioxia’s (formerly Toshiba Memory) flash. Only a few have tried different NAND combinations.

One of the first manufacturers to go against the gain and switch things up a bit was Kingston in releasing the company’s KC2000, and even recently when refreshing the line with the updated KC2500. Leveraging Silicon Motion’s SM2262EN and Kioxia’s 96L flash, the KC2500 blew us away with its performance under some of the heavier prosumer-type workloads. By switching up the norm, the company was able to create something a little more powerful than competitors for its target market.

Team Group is trying to do the same here. By pairing Phison’s new E12S along with Micron’s 96L TLC in the Cardea Zero Z340, the company has brought to market a rather interesting drive. With the newest hardware powering it, Team Group’s Cardea Zero Z340 offers a unique performance profile unlike any we’ve seen before, and it is not only very responsive, it has a high endurance rating, too.

The Cardea Zero Z340 comes in capacities of 256GB, 512GB, and 1TB, and street prices run as low as $0.14-$0.20 per GB, which is very price competitive with Adata’s XPG SX8200 Pro, one of the best values available right now. In terms of performance, the smaller capacities are a bit limited on write performance compared to the 1TB model, but can still deliver very fast read performance. Team Group rates the Cardea Zero Z340 to deliver sequential throughput of up to 3.4/3.0 GBps, and under random workloads it can sustain up to 450,000/400,000 read/write IOPS.

Team Group’s Cardea Zero Z340 comes backed by some very high write endurance ratings within its five-year warranty. Thanks to its Phsion NVMe SSD controller with the company’s third-gen LDPC ECC, our 1TB sample can endure up to 1,665 TB of writes over its warranty period, which is nearly triple the rating of Samsung’s 970 EVO Plus or WD’s Black SN750. Additionally, we were able to quickly secure erase the SSD with our motherboard’s UEFI tool. And with Linux and, as well, Trim and S.M.A.R.T. data reporting are both supported, too.

Team Group provides a basic S.M.A.R.T. data reporting tool to view drive information. It even has a built-in benchmarking tool to test performance, similar to Crystal Disk Mark.

The only downside to this material is that it is very flexible and will shape over the components underneath, rather than maintain a perfectly flat finish. Additionally, I was a bit disappointed to see a blue PCB rather than black, since even some of the company’s entry-level NVMe SSDs (Team Group MP33) come with black PCBs.

However, while the PCB’s color is less than exciting, the Phison E12S powering this little SSD is of much more interest. Built on dual ARM Cortex R5 processor cores operating at 666 MHz, alongside dual co-processors, the E12S is a very capable SSD controller. The R5s manage read/write requests while the co-processors operate at lower speeds and take care of some of the load for NAND management calculations for better efficiency.

It is also of a DRAM-based architecture for buffering FTL mapping tables and interfaces, with a Kingston 512MB DDR3L DRAM chip operating at 1,600 MHz, which is roughly half of the capacity that we have normally seen with the Phison E12. Additionally, the controller interfaces with sixteen dies of Micron’s 512Gb B27A 96L TLC NAND flash over eight NAND channels. There are four dies to a package, and these are 4-plane NAND dies operating at 666 MT/s. They feature a tile architecture that allows for 2KB tiles / 4KB tile groups for partial page reads and thus, very responsive random access, typically faster than cheaper 2-plane NAND designs.
