Throughput Benchmarks (SEQ and RND)
CrystalDiskMark
We are using CrystalDiskMark to benchmark the sequential and random throughput of read and write performance. For these NVMe SSDs, we are using the NVMe profile in CrystalDiskMark. This tests SEQ1M Q8T1, SEQ128K Q32T1, RND4K Q32T16, and RND4K Q1T1.
The Phison PS5028-E28 Reference Design 2TB SSD is rated at 14,900MB/s sequential read and 14,000MB/s sequential write. We achieved exactly that, hitting 14,914MB/s read sequential and 14,064MB/s write sequential. These results are the highest among all of the SSDs; the write performance is extremely impressive when compared with the other SSDs. The Phison PS5028-E28 Reference Design 2TB SSD sits above the MSI SPATIUM M580 FROZR, using the E26 controller, which used to be the champion on sequential performance here, but no longer. The E28 controller dethrones it, and really improves that write potential at 11% better write bandwidth.
In SEQ128K Q32T1, the Phison PS5028-E28 Reference Design 2TB SSD continues its dominance in read performance, with the highest bandwidth of 14,886MB/s. It is close in the write performance here with this particular workload, to the MSI SPATIUM M580 FROZR, both are within spitting distance, but the M580 FROZR takes a very slight lead. We must emphasize again that the Phison PS5028-E28 Reference Design 2TB SSD is using pre-release firmware, while the M580 was using mature firmware.
In RND4K Q32T16 performance, the Phison PS5028-E28 Reference Design 2TB SSD dominates all other SSDs here; in fact, we’d say the random performance is really a standout for this controller. At 8,765MB/s read and 8,561MB/s write, it’s unstoppable. The write performance is once again extremely strong, 46% more bandwidth than the next fastest SSD on here, the CORSAIR MP700 PRO in write performance. In read performance, it is 14% more bandwidth than the next fastest SSD.
In RND4K Q1T1 performance, the Phison PS5028-E28 Reference Design 2TB SSD is again very strong in read performance, with the highest bandwidth. The write bandwidth falls slightly behind the fastest drive here, but not by much, and again, it is pre-release firmware compared to mature firmware.
ATTO
Using the popular ATTO Disk Benchmark, the Phison PS5028-E28 Reference Design 2TB SSD results in the fastest bandwidth in both read and write performance. The write performance again is very dominant at 6% more bandwidth compared to the next fastest SSD, but compared to the slower ones, it’s a lot faster.
