THE SSD REVIEW TEST BENCH AND PROTOCOL
SSD Testing at TSSDR differs slightly depending on whether we are looking at consumer or enterprise SSDs. For consumer SSDs, our goal is to test in a system that has been optimized with our SSD Optimization Guide. Benchmarks for consumer testing are also benchmarks with a fresh drive so, not only can we verify that manufacturer specifications are in line but also, so the consumer can replicate our tests to confirm that they have an SSD that is top-notch. We even provide links to most of the benchmarks used in the report.
We should mention that, having recently introduced the new ASRock Z87 Extreme11/ac motherboard into our test environment, this motherboard has a very unique UEFI graphic BIOS, one that is very user friendly. Unlike many motherboards, this BIOS is set up standard for optimal settings and has an optimal setting for CPU states which is set automatically. For the most part, all CPU states are on with this motherboard.
This TSSDR Test Bench build was the result of some great relationships and purchase; our appreciation goes to the below mentioned manufacturers for their support in our project. Our choice of components is very narrow, in that, we choose only what we believe to be among the best available and links are provided to each that will assist in hardware pricing and availability, should the reader be interested in purchase.

The software we will be using for today’s analysis is typical of many of our reviews and consists of ATTO Disk Benchmark, Crystal Disk Info, Crystal DiskMark, AS SSD Disk BenchMark, PCMark Vantage and Anvil Storage Utilities. Most of this software is available free of charge and may be downloaded by clicking on the title…if it is free and downloadable that is.
ATTO Disk Benchmark is a relatively easy-to-use benchmark tool, which happens to be the benchmark of choice for many manufacturers. ATTO uses compressible data rather than random data, which results in higher performance and thus, higher benchmark scores. In our testing, we have selected the transfer size to range from 0.5KB to 8192KB, and have set the total length of the test to be 256MB.
Our initial ATTO results are right in line with listed specifications and this is much as we might expect from the Phison controller. Rather impressive is the steady increase in performance as file size increased, this generally being very representative of a strong SSD.
Crystal Disk Benchmark is visually straightforward, and is used for measuring the speeds at which your storage device reads and writes in both compressible (0Fill/1Fill) and random, mostly incompressible, data. Random data is more consistent with everyday use of a computer, such as transferring videos, pictures and music.
Crystal results were similar regardless of testing sample makeup and we were just a bit disappointed in the write performance, knowing of course that we are using a Phison controller and only two modules of memory. It was really a given and even Phison representatives would quickly point out that the intended direction for the SC2 family is that of a caching SSD,
AS SSD Benchmark uses incompressible data to test your storage device, essentially providing results that would be consistent with using the heaviest workload, thus lower speeds are expected. IOPS (Input/Output Operations Per Second) are seen in the first picture below and transfer speeds (MB/s) are the second.
Surprisingly, read performance remains very strong and we could point out several top tier SSDs that didn’t have high sequential read performance above 500MB/s in AS SSD. We also get a first look at IOPS and 38537 IOPS was better than we expected, although being nowhere near an upper tier score.
Similarly, the SC2 surprised us in AS SSD Copy Benchmark as the transfer speeds for the ISO and Game are excellent and better than we have seen from many other SSDs.
