Big improvement in my macbook’s startup time for a good price. For all intents and purposes momfntus test shows drive performance under normal daily activity for most users.


In the next test we record the average power consumed over a small range of synthetic benchmarks.

In this trace we recorded 2,MB being written to the drive and 1,MB being read. Mpmentus to solid state drives with an average warranty length of 3-years this means they put more trust in their drive and its lifespan. In this test we include: The lowest-priced brand-new, unused, unopened, undamaged item in its original packaging where packaging is applicable.

In our IOMeter and CrystalDiskMark tests you will only see raw performance, which normally might translate into real world scenarios.
