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 DQ16.
The software is used several different ways and 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
We're posting screen shots of our 3 drive array for this report. As you can see, sequential read/write speed has nearly tripled in comparison to a single drive. Write performance, especially 4K write performance, has increased tremendously due to write caching implementation.
0-Fill Compressible Read IOPS through Queue Depth Scale
One of the many reasons we're big fans of the Extreme II is because it has really good low QD performance. Looking at the chart, we find that RAID 0 is increasing read performance from a queue depth of 8 and above.
0-Fill Compressible Write IOPS through Queue Depth Scale
Write performance really benefits from RAID 0 when caching is enabled. Write performance is scaling very well. A 2 drive array is putting out nearly triple the performance of a single drive at QD1, and a 3 drive array even more! Look at the 3 drive arrays QD4 performance, it's approaching 200,000 IOPS!
Compression 100% Incompressible Data
For the most part performance does not vary from compressible to incompressible data. The 150 or so point differential is more than likely due to variations between runs, not so much the difference in data.
Incompressible Read IOPS through Queue Depth Scale
Nearly identical to our compressible IOPS scale.
Incompressible Write IOPS through Queue Scale
Again, nearly identical to our compressible IOPS scale. So, why do we chart incompressible IOPS? It will become apparent to you when you read our upcoming RAID reports featuring drives that utilize compression technology.
