Application Performance

Game Load Time

Gaming isn't a difficult workload on its own, but many of our readers care deeply about it. The Toshiba BG4 outperforms many of the popular low-cost SSDs shipping today although the results are very close among this group.

PCMark 8 Storage Bandwidth

The UL PCMark 8 Storage Bandwidth suite uses nine popular applications to run ten tests that range from loading PC games to Office document manipulation to heavy Photoshop use.

Of all the results, this is the most surprising from the Toshiba BG4. The drive performs remarkably well for it's small size and lack of a DRAM die to cache the flash translation map. It outperforms several big-name NVMe SSDs that we've recommended to uses in the past.

PCMark 8 Extended Storage Test

Even with all of the great performance we've measured thus far, the BG4 is still not a good choice for extended workloads. This test shows the drives nearly full and with heavy preconditioning. The BG4 is a pure consumer application drive, but that's not a negative in this context. It performs well in the tasks it Toshiba designed it for.

The Service Time Test shows how long each drive worked to complete the tasks. We rarely show this chart except to take a deeper look at DRAMless and 4-bit per cell SSDs. The DRAMless drives often take longer to recover after heavy workloads. That holds true with the Toshiba BG4. It simply takes longer for the drive to process the background activities that cleans flash cells to get performance back into an optimal state.
