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 Lexar NM800 PRO 1TB is up to 7500MB/s, and in our testing in SEQ1M Q8T1 we are getting that, it’s within the margin of error. At this performance, it is hitting at the top in CrystalDiskMark, competitive with the Acer Predator GM7000, and faster than everything else. It’s a fast drive. The write speed is rated at 6300MB/s, and we are hitting slightly over that, so it is performing as advertised. This puts it slightly behind the write speed of the Acer Predator GM7000 2TB and Adata Legend 960 1TB, but remember the 2TB version of the Lexar NM800 PRO is rated for a higher 6500MB/s write.
In SEQ128K Q32T1 it does slow down a bit but still is on the top-end of performance, outperforming the Patriot Viper VPR4000 by a good deal. It’s competitive with the Predator GM7, GM7000.
The Lexar NM800 PRO is performing very well in RND4K Q32T16 performance, up there near the top, outperforming write performance very well against the Predator GM7000 and everything except a few SSDs. It also has very good read speeds, again very competitive, and near the top here.
Even in RND4K Q1T1 performance, the Lexar NM800 PRO is performing well on read speeds, competitive with the top two SSDs. It’s a little slower on writes, but not the slowest.
