Throughput Benchmarks (SEQ and RND)


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 the graph above we are looking at the popular CrystalDiskMark’s sequential read and write performance. Remember, the Patriot Viper VPR400 1TB is rated at 4600MB/s read and 4400MB/s write speed. Well, we are getting much better performance than it is rated at, it is performing better than expected actually. We are getting 5173MB/s read and 4771MB/s write speeds. This puts it performing about 500MB/s greater than its rated read speed and 300MB/s faster write speeds than it is rated. At this performance level, it is beating the read and write speeds of sequential throughput of everything but the MSI SPATIUIM M480, which is a faster-rated SSD at 7000MB/s.

This is really great performance for the Patriot Viper VPR400 RGB SSD. The write speed is very impressive compared to the likes of the CORSAIR Force MP600 and MSI SPATIUM M470 which have been top performers in their tier until now.

The awesome sequential performance is followed in the Q32T1 testing, where the Patriot Viper VPR400 RGB 1TB SSD is once again pulling in the fastest read and write performance compared to everything else. Only the faster spec’d MSI SPATIUM M480 is faster.

If there is one weakness in the Patriot Viper VPR400 1TB SSD it is random write performance, and this may be due to the fact it has to write to system DRAM via HMB, or at least go to system DRAM for the lookup tables. Otherwise, it can hold its own in random read performance where it is in fact the fastest SSD on this graph, pulling 3115MB/s of throughput on read, this is faster than all the other SSDs on this graph. Therefore its random read performance is really really good. It is only beaten in its write performance by a good 1GB/s by the MSI SPATIUM M470 and CORSAIR Force MP400, which are in the same tier as this SSD. The MSI SPATIUM M480 is in a completely different tier level with the fastest spec’d performance, and that shows here in the write performance, but not the read, again the Patriot Viper is faster in random reads.

The same pattern is true in the random 4K Q1T1 testing, the read performance on the Patriot Viper VPR400 RGB 1TB SSD is above everything else at 90MB/s. But, it falls short in the write performance and is, unfortunately, beat by everything else in random write performance.
