Game Load Time
The high random mixed performance is what makes the 256GB EX920 so fast in applications tests. Just a year ago, the MyDigtialSSD BPX with MLC flash and a low price point blew us away. In a little over a year the EX920, with TLC flash, shaved more than a second off the Final Fantasy: Stormbood load time.
PCMark 8 Total Storage Bandwidth
The BPX is still a helluva drive. The MLC flash allows it to keep sustained write performance very high and in some media applications it's a nice, speedy, attribute to have. The BPX and MLC flash have both sold out and will never return, and now it's time to let the next generation shine. The 256GB EX920 is the best of this generation.
PCMark 8 Extended Storage Test
With the 1TB and 512GB drives, we never saw the EX920 fully recover in the five-minute idle time. We stated the drives do eventually recover and that we would show it in a later test. The 256GB drive with less flash to clean shows the recovery performance. The larger drives simply need more time after being hammered for hours with small block size data writes.
SYSmark 2014 SE System Responsiveness and Power Tests
Again we see the Adata, and HP drives with the SM2262 controller just one point apart in the BAPCo SYSmark 2014 SE Responsiveness Test. In the efficiency portion of the test, the EX920 rises near the top, and that should carry over to the battery life test in the next section.
Notebook Battery Life
As predicted, the Lenovo Y700-17 armed with the HP EX920 256GB delivers very good on-battery time. The MyDigitalSSD SBX is a better choice if you need to spread every electron out but the EX920 delivers a better user experience.
