Performance
Tests were performed on the Intel platform, which contains the i7-11700K processor, MSI Z590I Unify motherboard, and 32GB of DDR4-3600 memory. The results are exactly the same on the latest Z690 motherboards. Motherboards with AMD chipsets may provide a bit better results.
All tests were performed in Windows 11 Pro x64 with the latest updates.
Let’s begin with the ATTO Disk Benchmark, which is one of the most popular applications designed to measure storage bandwidth.
ATTO is a benchmark that surprised me the most. The specifications say that the UD90 is supposed to have up to 4800MB/s bandwidth. As we can see, ATTO shows up to 6.53GB/s! This is amazing and not something that we would expect.
CrystalDiskMark shows lower maximum sequential bandwidth but it’s still above the declared values. The maximum sequential read was as high as 5058MB/s.
More important is performance in random operations, and that is not much lower than we could see on the highest NVMe 4.0 SSD. Random low queue read is at about 85MB/s when the fastest SSD from the latest generation can make not much more than 100MB/s. Most NVMe SSD still can’t beat the UD90 in these tests.
In the 3DMark Storage Benchmark, we can see up to 608MB/s average bandwidth. The fastest SSD reviewed in our redaction is probably Silicon Power XS70 with about 715MB/s. The highest, and most expensive SSD of competitive brands are usually closer to 600-650MB/s, so the UD90’s performance is again exceptional.
The UD90 performs great in mixed-load tests like PCMark 10. This benchmark simulates daily work to show how fast is the used storage. Again, our results are higher than expected and beat some more expensive SSD.
Anvil’s Storage Utilities is an older but still popular benchmark. It’s a benchmark that usually shows lower bandwidth than expected, and it’s like that in this situation. Even though the results are high, then we can see only up to 3.7GB/s read and 4.3GB/s write bandwidth. On the other hand, the IOPS goes as high as 739K, which is an outstanding result.
In the end, AIDA64 Disk Benchmark which gives us another look at performance at random operations.
Both, read and write results, are quite high, but already far from the XS70 results. This is the only test in which we can clearly see that the highest SSD like the XS70, are clearly faster.
I’m usually skipping the AIDA64 sequential read test as it repeats the same results as ATTO or CrystalDiskMark. However, because of exceptional ATTO results, I wanted to present a confirmation that the 6GB/s is not only a single benchmark result. In AIDA64, we can also see 6GB/s when the SSD is rated at up to 4.8GB/s!
The UD90 SSD is not hard to recommend. Because of the lower price and outstanding results, it’s for sure a great option for all kinds of users.
