Sequential read transfers max out at 2.14 GB/s. Sequential write transfers max out at 1.24 GB/s.

 

Sequential Write

None of the PCIe drives can match the small file write performance of our 3-drive 600 Pro array. As file sizes increase, the AHCI SM951 and the DC P3700 run away from the pack. Of the PCIe drives, the SM951 NVMe has the best small file performance up to 8KB transfers.

 

Sequential Read

Both Samsung drives are able to massively outperform the Intel drives at transfer sizes up to 256KB. The SM951 NVMe is delivering 5x the performance of the Intel drives at 16KB transfers. However, our 600 Pro array dominates the field with superior small file performance up to 8K in size.

 

 

Anvil Storage Utilities

 

Version and / or Patch Used: 1.1.0

 

Anvil's Storage Utilities is a storage benchmark designed to measure the storage performance of SSD's. The Standard Storage Benchmark performs a series of tests; you can run a full test or just the read or write test, or you can run a single test, i.e. 4k QD16.
