Team Group MP34 on the controller Phison E12: straight-line speed without blockages

Today we are looking at the top model of NVMe SSD on Phison E12 series controller. This drive has a PCIe 3.0 x4 interface, promises speeds of up to 3GB/s for sequential reading and up to 1.8 GB/s for writing, but most importantly - it does not suffer from the typical SSD problems of the previous generation: it does not overheat and does not fill up the speed to the HDD level when full. That is, on the same memory Toshiba 64L 3D TLC, which is installed in most SSD drives, the novelty looks like a gift for enthusiasts and gamers, and just for ordinary users.

Drive has format 2280, as the cache memory using a single chip SK Hynix H5AN4G8NBJR of 512 MB, the very flash memory chips are 4 Toshiba TH58TFT0T23BA8C. On the diagram below are distinguishing features of the controller Phison E12


On Team Group’s website you can download T-Force utility to monitor your SSD to easily transfer data from your old SSD/HDD to a new one. To my surprise, the program does not know how to update the firmware of the drive, and in general it looks somehow damp.

I suggest not to waste time, and go directly to the tests. We will compare the new product with Transcend MT110S on the Silicon Motion SM2263XT controller.


  • Motherboard - ASRock Taichi X470 Ultimate
  • Processor - AMD Ryzen 5 1600
  • SSDS are connected to the first M2 slot
  • Memory - 32 GB
  • Windows 10
  • IOmeter, Pseudo pattern

Let’s start with a simple test Crystal Disk Benchmark, which will show us the maximum numbers. In General, this test has nothing to do with the actual performance of the drive, and we give it only for those who like beautiful numbers.

The main thing, of course, is almost 3.5 GB/s when reading and almost, but now even children know that it is necessary to look at the distribution of speed over time, for which we run the IOmeter test, fill 80% of the disk with random numbers, and start the tests.

And now the first test shows that there is no question of any 3.5 GB/s: at best we have about 1.2 GB/s, and in the initial area the performance of the controller is almost independent. Please note: “dispersion” in Transcend MT110S - only about 40%, but not 3-fold, as in Team Group MP34.

For older SSDS on the SM2263XT controller, a long sequential write beyond the SLC cache sizes is a disaster. In our test, the speed fell as much as 2 MB/s, and to show the difference in speed, we used a logarithmic chart with signatures. Yes, the new Team MP34 is 10 times faster, and the speed in the SLC cache area is even higher than in the children’s CrystalDisk Benchmark. Agree, the difference is impressive! By the way, the SLC cache area here is quite small: 14-15 GB.

The results of random reading - this is the only test in which the novelty frankly loses more than 20%.

But in a random record - almost 4-fold advantage over the old man, and the distribution of results - only twice. For comparison, at Transcend MT110S fell almost 20 times from the maximum.

Let’s move on to testing in patterns that emulate real-world tasks.

I do not know if you have considered NVMe SSD to store backups, but if so - Team Group MP34 will give in this pattern 600 MB/s with jumps up to 800 MB/s.

Simultaneous read + write are given to the drive relatively easily, but there is no crazy benefit compared to the previous generation.

Yes, the absence of failures in the recording allows you to speed up the batch conversion of photos…

… and a little bit - import of video files.

We recommend that you install Team Group MP34 in a slot that has a radiator. In idle mode, the SSD temperature is 37 degrees Celsius, rising to 51 degrees under normal operation. In the case of long intensive recording, even with the radiator the temperature reaches 63 degrees Celsius.


Compared to the previous generation of SSDS and budget drives, Team Group MP34 is a breakthrough! The real speed is impressive and you can expect 600-700 MB/s for your applications, and somewhere around 1.2 GB/s when copying large files. At the time of testing, this model was not presented in Russia, but it is expected that the price will be in the same area as the competitors: Adata XPG SX8200 Pro and Corsair Force MP510.

What I liked:

  • Stable speed throughout the drive
  • The absence of pronounced debris performance
  • Weak heating

What’s not to like:

  • Small area for SLC cache

In total, Team Group M34 is a great alternative to the much more expensive Samsung Evo 970, and for home use the drive can be considered in this key.
