In terms of write performance, it came in second to the HGST 10K900. The WD Xe slots into the middle of the pack, coming in just under the Seagate Savvio 10K.7 in read performance and trails the HGST 10K900 at the top of the pack. In the first of our enterprise workloads, we measured a long sample of random 4k performance with 100% write and 100% read activity to get our peak sustained random I/O results. We also included two legacy mixed workloads, the traditional File Server and Webserver, each offering a wide mix of transfer sizes. These profiles have been developed to make it easier to compare to our past benchmarks as well as widely-published values such as max 4k read and write speed and 8k 70/30, which is commonly used for enterprise drives. Our Enterprise Synthetic Workload Analysis includes four profiles based on real-world tasks. Latency Standard Deviation (Read+Write Standard Deviation Averaged Together).Max Latency (Peak Read or Write Latency).Average Latency (Read+Write Latency Averaged Together).Preconditioning and Primary Steady-State Tests: Since hard drives reach their rated performance level very quickly, we only graph out the main sections of each test. Our enterprise hard drive benchmark process preconditions each drive into steady-state with the same workload the device will be tested with under a heavy load of 16 threads with an outstanding queue of 16 per thread, and then tested in set intervals in multiple thread/queue depth profiles to show performance under light and heavy usage.
