Crucial MX100 256GB SSD Review

Anvil Storage Utilities


Version and / or Patch Used: RC6


So what is Anvil Storage Utilities? First of all, it's a storage benchmark for SSDs and HDDs where you can check and monitor your performance. The Standard Storage Benchmark performs a series of tests; you can run a full test or just the read or the write test, or you can run a single test, i.e. 4k QD16.


Anvil Storage Utilities is not officially available yet, but we've been playing with the beta for several months now. The author, Anvil on several international forums, has been updating the software steadily and is adding new features every couple of months.


We can use Anvil several different ways to show different aspects for each drive. We've chosen to use this software to show the performance of a drive with two different data sets. The first is with compressible data and the second data set is incompressible data. Several users have requested this data in our SSD reviews.



0-Fill Compressible Data




Incompressible Data




Compressible and incompressible write performance is the same on the MX100, so you won't notice a slowdown when working with pictures, audio, and other highly compressed files.



Low Queue Depth Read IOPS




We made a change on this page and divided the low queue depth performance from the high queue depth performance. Consumers should focus mainly on low queue depths, even though manufactures advertise high queue depth performance. The QD1 IOPS rating has a red highlight around it since it's one of the most important metrics to look at.


The MX100 256GB delivers nearly 8,200 random read IOPS at QD1. The drive scales well from there, doubling at QD2 and nearly doubling again at QD4.



High Queue Depth Read IOPS



It's rare for consumers to reach the high queue depths shown in this chart, but with heavy multitasking and intense tasks, like booting the system, they are possible. The MX100 nearly hit 100K IOPS in our QD32 read test.



Low Queue Depth Write IOPS




It's easier to reach higher queue depths when writing data while multitasking.



High Queue Depth Write IOPS




The Crucial MX100 256GB achieves nearly 80K random IOPS at QD4 and then everything levels off in this chart, but we don't see the performance shrink as the load increase.
