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.
The Acer FA200 4TB PCIe Gen4 M.2 NVMe SSD has a rated sequential read speed of 7,100MB/s and a rated sequential write speed of 6,100MB/s. In our CrystalDiskMark testing, SEQ1M Q8T1, we are achieving that performance and more, surpassing the rated speed actually. The Acer FA200 4TB PCIe Gen4 M.2 NVMe SSD is hitting 7,296MB/s read and 6,323MB/s write, so it is definitely working as advertised, and then some. There is no issue at all with sequential read and write performance on this SSD. It hits its target, which places it slightly above the Netac NV7000-Q QLC SSD here, with a faster write speed as well.
Again, in SEQ128K Q32T1, the achieves its rated sequential read and write speeds, surpassing the quoted speed with 7,304MB/s read and 6,245MB/s write. This again puts it slightly above the Netac NV7000-Q on performance.
This graph is sorted by write speed. In RND4K Q32T16 performance, the Acer FA200 4TB PCIe Gen4 M.2 NVMe SSD shows its overall weakness compared to the grouping of SSDs here. It achieves 3,551MB/s write performance in random 4K Q32T16, which places it near the bottom of the graph, slightly faster than the Lexar NM710. It performs just under the Netac NV7000-Q, for both read and write performance.
This graph is sorted by read performance. In RND4K Q1T1 performance, we again find the Acer FA200 4TB PCIe Gen4 M.2 NVMe SSD’s weakness, at 70.31MB/s read, it is nearer to the bottom, faster than the Netac NV7000, and Lexar NM710, but slower than everything else here, even the Netac NV7000-Q. It also has quite a drag on the write performance, at just 220MB/s, it has the lowest random 4K Q1T1 write performance on this graph. Overall, random reads/writes are this drive’s weakness.
ATTO
Using the popular ATTO Disk Benchmark, the Acer FA200 4TB PCIe Gen4 M.2 NVMe SSD is hitting 6.81GB/s read and 5.71GB/s write, which does put it above the Netac NV7000-Q.
