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




The controller in the Intel SSD Pro 2500 is able to compress data that isn't already compressed. The data compressed in real-time by the controller actually writes faster to the flash because there is less data to write. This also reduces wear to the flash. The only down side is previously compressed data writes to the drive slower than compressible data.



Low Queue Depth Read IOPS




This first chart is one of the most significant in the entire review. Companies like to talk about high queue depth performance, but most of us will never stack that many commands on an SSD, because the drives are already very fast.


For consumer SSDs, we want to look at low queue depth performance. The Intel SSD Pro 2500 achieves over 8600 read IOPS at QD1 and the IOPS performance nearly doubles at QD2. By queue depth 4 with random data, the 2500 nearly breaks into the 30,000 read IOPS range.



High Queue Depth Read IOPS




In our test where we double the queue depth with each pass, the Intel SSD Pro 2500 reaches peak random read IOPS at QD16, just over 64,000, then drops back down to 45,000 at QD32.



Low Queue Depth Write IOPS




It's easier for consumers to reach higher queue depth levels when writing data than reading it. This is especially true when multitasking.



High Queue Depth Write IOPS




The Intel SSD Pro 2500 only reached 539,000 4K write IOPS at QD32. While slower than many performance leading consumer SSDs, the Pro 2500 is still much faster than a mechanical disk drive.
