Performance
The performance has been tested on the Intel platform, which contains the i7-11700K CPU, MSI Z590I Unify motherboard, Acer Predator 16GB DDR4-3600 CL14 memory kit, and ASUS Strix RTX3070 graphics card.
All tests were performed in Windows 11 Pro x64 environment with the latest updates. The OS was installed on another SSD.
As usual, in my storage reviews, I will start with the ATTO Disk Benchmark. It’s one of the most popular storage benchmarks, and the results are easy to compare at home.
The ATTO benchmark is usually showing results lower than expected, and it’s not any different right now. The maximum bandwidth in this benchmark is 6.61GB/s for both, read and write tests. Even though it’s not as high as we wish to see, then it’s slightly higher than on other, similarly rated SSD. In short, all SSD specified for up to 7400MB/s, reach about 6.5-6.6GB/s in this test.
The maximum bandwidth on our test rig was slightly above 7000MB/s. Since we are using a motherboard with an Intel chipset, then we can’t count on much more. The specified 7400MB/s is possible on the latest motherboards with AMD chipset, but at the time of this review, it wasn’t available. Additionally, Windows 11 still has some problems with NVMe SSD and some of the results are lower than on Windows 10. Since the market moved to Windows 11 some months ago then we won’t go back too, but we wish to see some updates from Microsoft as this problem is already well-known for over half a year. On the other hand, out of benchmarks, we probably wouldn’t see the difference anyway, so there is nothing to worry about.
CrystalDiskMark shows us exceptional results in random operations. There are not many other SSD that perform better in these tests.
Let’s look at UL PCMark series benchmarks as in these tests; we can see how the SSD performs in a mixed load environment, which simulates real-world workload.
In PCMark 10, the results are excellent as expected. These are maybe not the best results we have seen but are solid top 3.
3DMark Storage benchmark usually repeats PCMark 10 results while here is a little surprise as the TWSG4S achieved the best result, about 50MB/s higher than the last top bandwidth.
Anvil’s Storage Utilities is an older benchmark but still popular, so why not use it?
Even though results are, as usual, lower than we wish, then they are still pretty high. The maximum IOPS in this benchmark is about 876K which is again the top score looking at our previous storage reviews.
The last test is AIDA64, which shows us the performance based on random operations, divided into reading and writing. These tests take about 11 minutes each on the TWSG4S, so significantly less than on an average PCIe 4.0 SSD.
The random write bandwidth could be higher as we’ve seen better results, but it’s not really important for the target users, so gamers.
ZADAK TWSG4S is clearly one of the fastest SSD on the market which looks especially well in game-related tests.
