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.
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 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
Being an LSI SandForce controller, there is a difference in performance between compressible and incompressible data. At the same time though, the write amplification is less than 1 with the SF-2281.
That means the SSD is actually writing less data to the flash than is actually being sent to the controller. As flash program erase cycles shrink with smaller die processes, DuraWrite becomes an even bigger advantage.
Read IOPS through Queue Depth Scale
Companies are still marketing their high queue depth performance for consumer SSDs, but we like to highlight the low queue depth IOPS performance level, since most consumers will never get beyond QD4.
The SX300 256GB delivers 9,107 4KB read IOPS at QD1. This is the second best result on the chart, even higher than the Intel 525 240GB mSATA drive with 25nm flash.
Scaling Write IOPS through Queue Scale
At nearly 30K IOPS at QD1 when writing data, the SX300 256GB is very quick and will feel fast in your system. The LSI SandForce architecture has always felt very fast in real-world use.
