Crucial BX100 1TB SSD Review

Mixed Workload And Steady State Performance

Our mixed workload testing is described in detail here, and our steady state tests are described here.

For the money, Crucial's BX100 1TB delivers high sequential mixed workload performance. We want to focus mostly on the QD4 to QD8 range for typical consumer workloads. The high sequential read speed really helps the drive, while the mix of sequential writes doesn't hurt this product as much as it does others.

Given the low random performance observed in our four-corner testing, it's easy to see why the BX100 falls to the lower end of our random mixed workload performance chart. There really isn't a way around it: Crucial's BX100 doesn't deliver random performance as well as we'd like.

128KB Sequential Mixed-Workload Steady State Performance

For many, the steady state tests don't match the daily workloads encountered by drives in this price category. Still, we like to run them because they unearth the real solid-state gems, and Crucial's BX100 is one such diamond. Any time you work with large files that are moved sequentially, this drive fares well.

4K Random Write Steady State Performance

Although this test has little to do with real-world performance, it does show us how the SM2246EN controller handles random data. Without fresh blocks, the 4KB random writes fall below 5000 IOPS. When the garbage collection schemes find a clean block to write to, the write happens faster than expected. The BX100 demonstrates a wide range, though, from clean and dirty writes.
