Samsung 850 EVO 250GB 3D V-NAND SSD Review

Sequential Mixed Read / Write Workloads

 

In this series of tests, we measure mixed workload performance. We start with 100% read, and then add data writes to the mix in 10% increments until we get to 100% writes. We believe this will be the next major area SSD manufacturers will address, after performance consistency.

 

Sequential Mixed Workload Bandwidth

Our mixed workload test that runs with the drives preconditioned to simulate real work on high bit rate video has proven to be difficult for consumer SATA SSDs. SATA is half duplex; data can only be read or written at any one time. Asking a drive to read and write at the same time under high queue depth conditions causes performance loss over what you would have in normal consumer workloads. 4K video has entered the consumer market, and as this type of workload moves to the mainstream, SSDs provide the best and fastest way to edit the data.

 

Sequential 80% Read / 20% Write Bandwidth

The 80% read with 20% write mix is closer to what consumers work under, although not always in a steady state.

 

Random Mixed Workload Response Time

Mixing reads and writes with random data is also a difficult task for many consumer SSDs. However, Samsung's two V-NAND SSDs both do really well under these conditions.
