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.

 

The software can be used 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

The Crucial M550 works with both compressible and incompressible data the same way, so performance stays the same regardless of data type.

 

 

Read IOPS through Queue Depth Scale

Low queue depth 4k read performance is very close to other leading drives in this capacity size. The M550 256GB achieves nearly 8700 IOPS at QD1, and the drive scales well from that point. At the high-end, the M550 256GB nearly achieves 100k IOPS at QD32 in our test.

 

Scaling Write IOPS through Queue Scale

We're very impressed with the M550's 4k IOPS performance at low queue depths. At QD1, the 256GB model delivers 37,000 IOPS, but at QD2, the IOPS jump to just over 70,000. The 64Gb die allow the M550 256GB to scale all the way to 88k IOPS at just QD4, a rate that holds all the way to QD32.
