When you're purchasing a 512GB capacity class SSD, there isn't much of a difference between $300 and $320. For twenty dollars more than the Angelbird SSD wrk 512GB costs, you can purchase the SanDisk Extreme II 480GB, which is the fastest SSD in this price range. It's not that the SSD wrk 512GB is a bad SSD, it's just that there are other, better options. Here we see the three states of performance for the select SSDs, which are light use, consumer steady state, and worst case. PCMark 8's Consistency test provides a ton of data output that we use to judge a drive's performance. Run writes of random size between 8*5*512 bytes on random offsets for 50 minutes.ģ. Repeat steps one and two, eight times, and on each pass increase the duration of random writes by five minutes.ġ. Run writes of random size between 8*5*512 bytes on random offsets for ten minutes.ģ. Write the drive through a second time (to take care of overprovisioning).ġ. Write the drive sequentially through, up to the reported capacity with random data.Ģ. To do that, the drive gets pushed down to steady state with random writes, and then idle time between a number of tests allows the drive to recover.ġ. PCMark 8 Consistency Test Futuremark PCMark 8 Extended - Consistency Testįuturemark's PCMark 8 allows us to wear the test drive down to a reasonable consumer steady state, and then watch the drive recover on its own through garbage collection. In this test, the Angelbird SSD wrk actually does very well, as do the other SM2246EN controlled drives. On this chart, we see the random mixed IO workload.
