Throughput Benchmarks (SEQ and RND)
CrystalDiskMark
We are using CrystalDiskMark to benchmark 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.
In CrystalDiskMark Sequential 1M Q8T1 testing, the Acer Predator GM7 1TB SSD performs right under the performance of the Acer Predator GM7000, and ADATA LEGEND 960. This sits right where BIWIN said it should. It is nearly only 40MB/s slower in read performance, and 300MB/s slower in write performance compared to the Acer Predator GM7000. It’s actually faster than the MSI SPATIUM M480 in read performance and beats the PATRIOT VIPER VPR400, and CORSAIR Force MP600 in write performance by a lot.
The same is also true in Sequential 128K Q32T1 testing, the Acer Predator GM7 1TB SSD sits right under the ADATA LEGEND 960 and Acer Predator GM7000 in performance. Its read speed is only 50MB/s slower than the GM7000 and its write speed is 400MB/s slower than the GM700, these are very small differences.
Random performance is what always trips up performance on SSDs, and so we want to look at this closely here. The fact that the Acer Predator GM7 1TB SSD is coming in toward the top of the chart here on read performance is very important. It is under the Acer Predator GM7000 and ADATA LEGEND 960, the same as it was in sequential performance. Here we see it’s about 400MB/s slower in read performance compared to the GM7000, which again is not a huge amount considering it is DRAM-less. It outperforms the PATRIOT VIPER VPR400, both MSI SPATIUM SSDs, and the CORSAIR Force MP600. The random write performance also seems to be very competitive, it’s about 500MB/s less than the GM7000. However, it beats the PATRIOT VIPER VPR400. The MSI SPATIUM drives, especially the M480 have insane write performance.
In Random 4K Q1T1 performance we have scaled the graph by read speed, which is often the lowest performing in this test. This puts the Acer Predator GM7 1TB in about the middle-of-the-road in performance, compared to the other SSDs. It’s not the worse, but also not the best. The Acer Predator GM7000 is about 10MB/s faster on read and 30MB/s faster on write. This isn’t the worse read performance though, the MSI SPATIUM drives are lower, as well as the CORSAIR Force MP600, though their write speeds are much higher.
