4-Corner and Then Some Performance


Let's start the testing off with a quick look at the HP Z Turbo SSD's 4-corner performance. In these tests, we measure sequential and random reads and writes. We also measure a limited amount of mixed workload performance.



Initial Performance Evaluation - 4-Corner and Then Some Tests


Sequential Read




Sequential Write




Sequential 80% Read 20% Write




The HP Z Turbo scales very well in RAID 0 when reading and writing sequential data. The single card performs very well too.


Random Read




Random Write




Random 80% Read 20% Write




The RAID 0 only shows a small performance increase over a single Z Turbo drive in random reads. The random write test with two drives shows a larger performance increase, but not nearly as large as the gains we see when working with sequential data. Mixing random reads with random writes narrows the gap even further.
