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 Samsung 840 EVO does not slow when working with incompressible data like LSI SandForce or Phison controllers. The aggressive garbage collection though does mean write amplification exceeds 1.
Read IOPS through Queue Depth Scale
One of the key points at the 2013 Samsung Global SSD Summit was Samsung's new outlook on IOPS performance. For the last year TweakTown has stressed low queue depth performance and many manufacturers have stressed high queue depth IOPS performance.
Under normal client loads, you rarely see the depth increasing past 4. Samsung acknowledged that at the conference and now wants to focus on QD1 and QD2 IOPS. The 840 and 840 PRO do well at low QD, but the 840 EVO was optimized for low queue depth performance. With RAPID Mode enabled the low QD performance is simply amazing.
I'm using the 750GB drive in the notebook I'm typing on right now and the difference between this drive and the Intel DC S3700 800GB (that I took out last night) is pretty amazing. The S3700 isn't what I would expect to find in most notebooks, but sometimes you just have it like that.
Scaling Write IOPS through Queue Scale
I had a good laugh when I saw the ridiculousness of this chart. RAPID Mode allows the 840 EVO to become a new category of SSD. I can already hear the calls by other manufacturers claiming Samsung is somehow cheating.
Samsung's RAPID Mode is as significant as the SSD was to the HDD. It's just another level of performance that we really didn't know existed, until it was handed to us.
