Samsung 850 Pro 128GB SSD Review

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.


The software can be used 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




Regardless of the data type, the 850 Pro 128GB delivers a bit over 5,400 combined score in Anvil's test. That means like other Samsung SSDs, performance doesn't drop when working with incompressible data. Also, the 1TB model achieved just over 5.600 so the 128GB model doesn't lose a great deal of performance over the fastest model of the group.



Read IOPS through Queue Depth




The magic number for queue depth 1 random read performance is 10K IOPS. Very few SSDs manage to hit this mark, even enterprise models. The Samsung 850 Pro does achieve over 10K random read IOPS at QD1 and the performance scales well as the depth increases.


Write IOPS through Queue Depth




Technologies such as Samsung's Turbo Write, SanDisk's nCache and IMFT's L85C flash use a SLC like layer controlled by the flash translation layer to hit high random write speeds. The 850 Pro does not use Turbo Write like the 840 EVO so the random performance we see in this 1GB of data test is what you get regardless of the amount of random data you write to the drive.
