The original 480GB ADATA SX8200 outperformed the 512GB HP EX920 in many tests. It's not uncommon to have one drive series win the top performance spot in one capacity but lose in another. It's just something we haven't seen in the years when Samsung dominated the consumer market. The SX8200 in this capacity is faster than the EX920, but the new SX8200 Pro is even faster in our game load time test using Final Fantasy: Stromblood.
PCMark 8 Total Storage Bandwidth
The PCMark 8 Storage Test uses a wider range of consumer applications. The tests applications use random and sequential data to give and better representation of consumer performance. The MyDigitalSSD BPX Pro performs really well here thanks to strong sequential performance. The new 512GB ADATA SX8200 Pro is even better. We observed a 56 MB/s lead with the SX8200 Pro, but the results are so close that it would be difficult to spot the difference under real-world conditions.
PCMark 8 Extended Storage Test
The Samsung 970 EVO still enjoys a lead under heavy workloads thanks to it's 5-core controller and resilient V-NAND memory. The SX8200 Pro improves on the heavy workload performance over its predecessor, but the heavy reliance on caching technology leaves workstation users inconsistent performance. In the recovery phases of the test where most consumers work, the SX8200 Pro shows strong performance again with a fast recovery. This is a significant improvement over the SX8200, but ADATA is still off the mark for workstation use with this drive.
SYSmark 2014 SE System Responsiveness and Power Tests
The SYSmark 2014 SE test features a unique test that measures the user experience through system responsiveness. The test follows an office worker through a day including idle time for coffee breaks.
The ADATA SX8200 Pro outperforms the HP EX920 by two points in this test. An OEM version of the Samsung 850 EVO is the base for this weighted score and represents 1,000 points on the scale.
Notebook Battery Life
Our final test also comes from BAPCo, and it uses many of the same workloads as the SYSmark test. This test runs on a Lenovo Y700-17 gaming notebook. The 512GB SX8200 Pro scores 324 minutes on the system, nearly 5.5 hours running office applications. This is right around the category average for NVMe SSDs.
