The Crucial MX500 500GB SSD Review: A Second Lookby Billy Tallis on February 2, 2018 9:30 AM EST
AnandTech Storage Bench - Light
Our Light storage test has relatively more sequential accesses and lower queue depths than The Destroyer or the Heavy test, and it's by far the shortest test overall. It's based largely on applications that aren't highly dependent on storage performance, so this is a test more of application launch times and file load times. This test can be seen as the sum of all the little delays in daily usage, but with the idle times trimmed to 25ms it takes less than half an hour to run. Details of the Light test can be found here. As with the ATSB Heavy test, this test is run with the drive both freshly erased and empty, and after filling the drive with sequential writes.
Most drives show a larger difference between full drive and empty drive performance on this Light test than on the Heavy test. Like the MX300, the Crucial MX500 continues to show a more pronounced full-drive performance hit than most of its competition. This effect has been reduced so that the MX500 is faster than all the earlier Crucial drives whether the test is run on an empty drive or full drive. Peak empty-drive performance hasn't improved much, so Crucial hasn't caught up to Samsung.
The Crucial MX500's average and 99th percentile latency scores when the Light test is run on a full drive show a bit more performance drop than most of its competition, but it is not a big outlier the way the MX300 was.
The full-drive average read and write latencies for the Crucial MX500 are a bit higher than what Samsung's drives deliver, but overall the MX500's latency is pretty good.
The Crucial MX300's 99th percentile read and write latencies were both significant outliers among mainstream SATA drives, while the MX500 blends in with more or less the same quality of service level as the competition.
As with the other ATSB tests, the Crucial MX500 draws more power than the MX300, but this time it remains one of the most efficient mainstream SATA SSDs, albeit with a small lead.
