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
The two results above were without RAPID and we can see there is very little variation between compressible and incompressible data workload.
Read IOPS through Queue Depth Scale
If you missed the 840 EVO Overview article then you should go back and read about the fine details of what Samsung is pushing with low queue depth IOPS performance. We stated publishing low queue depth IOPS performance because several manufacturers were emphasizing their high queue depth results.
In a consumer environment, you will rarely hit a queue depth higher than four. Achieving the famed 100K IOPS at QD32 is like finding a unicorn, it just isn't going to happen. We're glad to see Samsung shifting their focus to low QD IOPS performance.
On the read side, RAPID doesn't do much for low QD IOPS performance, unless the data is cached. Even without RAPID, the 840 EVO manages to outperform everything else on the chart at QD1, even the 840 PRO.
Scaling Write IOPS through Queue Scale
As stated earlier, some of the charts are going to get a bit wonky. Without RAPID, the 840 EVO does well with low queue depth IOPS. It's not the fastest on its own, but it's still in the top tier with the 840 PRO and Vector. With RAPID enabled, the 840 EVO is in a new class of SSDs. We've called 840 PRO and Vector the hyper class SSDs. At this point, I don't even have a way to define 840 EVO with RAPID mode enabled.
The above hyper class 840 EVO won't give you this level of write IOPS performance for the full span of the drive, but since we are talking about consumer use, it doesn't really matter. Perceived performance, also known as user experience, is more important than an artificial benchmark. Samsung has realized this and taken user experience to another level.
