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 rated sequential read speed on the ADATA LEGEND 970 2TB SSD is 10,000 MB/s read and write. In the SEQ1M Q8T1 test, we are definitely hitting that mark, in fact, a little ahead on write performance, which is incredible. The read speed is hitting 10,079MB/s and the write speed is hitting 10,192MB/s. This puts it at 2,626MB/s faster on read speed compared to the ADATA LEGEND 960 and 3,536MB/s faster on write speeds. Compared to the second fastest SSD on the graph, the new ADATA LEGEND 970 offers 2,599MB/s faster read speeds and 3,520MB/s write speeds.
In SEQ128K Q32T1 the ADATA LEGEND 970 2TB also hits its mark at 10,017MB/s read and 10,193MB/s write performance. While the Gen4 SSDs had a lot lower write performance compared to read, the ADATA LEGEND 970 actually has a slightly higher write performance than its read, it’s very balanced on read and write sequential performance.
In RND4K Q32T16 performance the ADATA LEGEND 970 2TB SSD is very strong against all the Gen4 SSDs. It offers a lot more random read and write performance, and once again we see its write performance outperform the read performance. At 6,113MB/s read it is 1,981MB/s ahead of the ADATA LEGEND 960 on read and 3,270MB/s on write. Compared to the fastest SSD, it is ahead on read by 1,701MB/s and compared to the addlink S95’s write performance it is still ahead by 1,161MB/s.
In RND4K Q1T1 performance, the ADATA LEGEND 970 2TB is once again extremely strong in its write performance. At 293MB/s it outperforms the ADATA LEGEND 960 by 75MB/s on write performance and 17MB/s faster than the addlink S95 write performance. It falls slightly short on read performance, where it performs a few MB/s slower than the ADATA LEGEND 960, but still very close, in this test the write performance is extremely impressive.
