Review ssd teamgroup cardea zero z340 512gb: "bon chen" the high-end segment

TeamGroup's Cardea Zero Z340 SSD has strong performance with a unique, eye-catching and really effective graphene heatsink. In the high-end segment, this is a potential name worth considering, whether you are a gamer or not.

TeamGroup has been quite busy expanding its range of NVMe (Non-Volatile Memory Express) (SSD) products, see also: What are NVMe SSDs? Should you buy them?), With stock The new range of names spans all segments. In addition to the Cardea Zero Z440 for computer systems that support the new PCIe 4.0 communication standard, TeamGroup also launched the Cardea Zero Z330 and Z340 for users who have not yet wanted to upgrade, still using PCIe 3.0 capital. had enormous bandwidth and was redundant with most of the work.

As a higher-end series, the Cardea Zero Z340 offers a maximum read / write (sequential) speed of up to 3,400 / 3,000 MB / s, many times faster than traditional hard drives and standard SATA SSDs. VnReview hand-held version with 512GB capacity, currently priced at 79 USD (refer to Newegg) or 1.8 million VND, with a 5-year warranty policy.

Open the box and design overview

Like the MP33 that VnReview recently reviewed, the Cardea Zero Z340, even in the higher segment, was packed very simply inside a small card with important parameters on the outside. On the front, we can see information such as 512GB capacity, PCIe Gen3 x4 NVMe standard, and TeamGroup of course not forgetting to mention the ultra-thin graphene and copper heatsink, for better cooling efficiency 9 %.

Meanwhile on the back, two important information that we need to keep in mind is speed, depending on the capacity, the drive will have different speeds, and TeamGroup's up to 5 year warranty policy.

Coming to the main character, the Cardea Zero Z340 has a standard M.2 2280 design, compatible with most desktop systems or ultra-thin ultrabook lines. The graphene heatsink is very thin, as announced by TeamGroup is only 0.2mm thick, so if your motherboard has a built-in heatsink for SSD, the Cardea Zero Z340 will still be compatible without problems. what.

The stylized graphene heatsink looks pretty eye-catching, but unfortunately TeamGroup decided to choose blue for the printed circuit (PCB) instead of black, I'm sure the black will be nice and create good visual effects. than.

On the back, we have a sticker with product information such as serial number, warranty period and notes you will not be warranted if you lose or damage that sticker.

Due to having to remove the graphene heatsink in order to see the controller and the NAND inside, we decided to do our own research with the information provided by a TeamGroup representative. Accordingly, responsible for the performance of the Cardea Z340 will be the Silicon Motion 2262EN controller, 96-layer 3D NAND TLC flash memory (BiCS5) and the DRAM SLC cache.

Performance and practical use

As announced by TeamGroup, Cardea Zero Z340 512GB version for sequential read / write speeds up to 3,400 / 2,000 MB / s. Durability, in terms of Terabyte Written (TBW) units reached 800, which is more than double that of the MP33.

Testing the performance of Cardea Zero Z340, VnReview uses the system with the following configuration:

CPU: AMD Ryzen 5 3600

Motherboard: MSI B450m Mortar Max

- RAM: TeamGroup T-Force XTreem ARGB 2x8GB bus 3200MHz

Graphics Card: Zotac GTX 750Ti

- SSD: TeamGroup Cardea Zero Z340

- Source: Antec EA750G Gold Pro 750W

To copy the actual data, VnReview chose two contexts: to copy the folder containing the data of the 12.4 GB game League of Legends with many different size files and subfolders, and copy 600 jpg file sizes ranging from 2-15MB, 2.21GB total.

Data copy speed of the game League of Legends

Copy speed 600 jpg image files

In the first context, the Cardea Zero Z340 initially hit 1.2 GB / s, dropping to 750-900 MB / s after running out of cache until the end. As for copying image files, the Cardea Z340 Zero fluctuates a lot, from 300-700 MB / s.

Crystal Disk Mark is the most popular hard drive benchmark today, manufacturers often take sequential read and write parameters (top line) to promote products. The Cardea Zero Z340 that VnReview had in hand had sequential read / write speeds of 3,459 / 2,435 MB / s, both higher than announced by TeamGroup. The drive's random data access speed is not bad, 60/227 MB / s in turn, but it is not really outstanding.

Similar in function to Crystal Disk Mark but AS SSD is less popular because it uses uncompressed data, so the results are often lower and more accurate.

AS SSD also has another tool, Compression Benchmark, measures the data compression rate of the hard drive with compression from 0% to 100%. In theory, this ideal result is as straight and as high as possible, indicating stability of the controller. The Cardea Zero Z340 "hiccup" at 45% and 95% when the write speed was significantly reduced, possibly due to caching, while the blue line, showing the data read speed, shows stability. high.

ATTO Disk Benchmark is software that includes a series of tests to determine the read and write speed of hard drives with many different size data packets. The Cardea Zero Z340 started to hit the top speed threshold at I / O size 256KB, with read speeds of 3.23 GB / s and 2.27GB / s write.

In terms of gaming performance, SSDs outperform traditional hard drives thanks to their high read and write speeds, resulting in significantly reduced screen loading times. The Final Fantasy XIV: Shadowbringers benchmark is a reliable tool that measures standard stage load times to milliseconds.

Since VnReview's GTX 1660 Super graphics card is having problems, we are temporarily using Zotac's GTX 750Ti, so the graphics settings during the benchmark have also been reduced to match the performance. In total, the Cardea Zero Z340 loaded all 5 levels in 11,688 seconds, an impressive number and much faster than the MP33 with 17.9 seconds.

The temperature of the drive when benchmarking is in ezIOmeter. Readers click on the image to view in large size

In terms of operating temperature, we monitored the drive's temperature while performing a long-range ezIOmeter benchmark using the HWmonitor software. During the benchmark, the highest temperature recorded by HWmonitor was 59 degrees Celsius. This figure is much lower than Western Digital's SN750, which goes up to 71 degrees Celsius when processing heavy data. Thus, it can be seen that the graphene heatsink really works, and this could be the biggest advantage of the Cardea Zero Z340 when compared to competitors in the segment.


Overall, the Cardea Zero Z340 is a good NVMe SSD both in design and overall performance, but this SSD also dominates the graphene thermal solution that prevents the drive from "squeezing" performance when overheating, one thing. Needed if your motherboard does not have an SSD heatsink available. In addition, a 5-year warranty period and 800 TBW durability will bring peace of mind to users for daily use. Unless you have a newer PC system, with PCIe 4.0 and are willing to spend extra money, the Cardea Zero Z340 is more than enough for everyday needs, whether you're a gamer or not.
