👁 Flexible IO Tester benchmark with settings of Type: Random Read, Engine: IO_uring, Direct: Yes, Block Size: 4KB, Job Count: 8, Disk Target: Default Test Directory. WD_BLACK SN8100 2TB was the fastest.

For carrying out random reads with FIO, the WD_BLACK SN8100 was the easy front-runner for these consumer NVMe SSD benchmarks on Ubuntu Linux.

👁 Flexible IO Tester benchmark with settings of Type: Random Write, Engine: IO_uring, Direct: Yes, Block Size: 4KB, Job Count: 8, Disk Target: Default Test Directory. WD_BLACK SN8100 2TB was the fastest.

For random write performance with FIO, the WD_BLACK SN8100 continued to perform much faster than all of the other solid-state drives benchmarked this round.

👁 Geometric Mean Of All Test Results benchmark with settings of Result Composite, WD_BLACK SN8100 2TB Linux Ubuntu Benchmarks. WD_BLACK SN8100 2TB was the fastest.

I've only had a few days since purchasing the WD_BLACK SN8100 2TB SSD but overall it's working well on Linux in being faster than the other PCIe Gen5 NVMe SSDs recently re-tested as well as being a nice upgrade over the WD_BLACK SN850 series except for some oddities with MariaDB. More tests are ongoing of the WD_BLACK SN8100 under Linux so stay tuned to Phoronix for more benchmarks in follow-up articles.

The WD_BLACK SN8100 2TB can be found for around $279 on Amazon.com (affiliate link).
