TSSDR 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. To see the best performance possible the CPU C states have been disabled, C1E support has been disabled, Enhanced Intel SpeedStep Technology (EIST) has been disabled. 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.
This Test Bench build was the result of some great relationships and purchase; our appreciation goes to those who jumped in specifically to help the cause. Key contributors to this build are our friends at ASRock for the motherboard and CPU and be quiet! for the PSU and cooling fans, and Kingston for the RAM. We have detailed all components in the table below and they are all linked should you wish to make a duplicate of our system as so many seem to do, or check out the price of any single component. As always, we appreciate your support in any purchase through our links!

The software in use for today’s analysis is typical of many of our reviews and consists of TRIMcheck, ATTO Disk Benchmark, Crystal Disk Mark, AS SSD, Anvil’s Storage Utilities, Iometer, PCMark Vantage. We prefer to test with easily accessible software that the consumer can obtain, and in many cases, we even provide links. Our selection of software allows each to build on the last and to provide validation to results already obtained.
We’ve covered TRIMcheck in the past. It is a great tool that easily lets us see if TRIM is actually functioning on a SSD volume in your system.
Since we are utilizing these SSDs in RAID 0 we wanted to see if TRIM was functioning or not. As it seems, TRIMcheck came back with positive results just as we had hoped! This also confirms Windows software RAID allows for TRIM no issue.
ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.
ATTO shows us some great speeds starting off. Compared to our single SSD results, nearly all speeds per file size have increased, even small 0.5KB-4KB files! Once it reached the 128KB file size speeds reached near peak. The RAID 0 volume is able to achieve 2.6GB/s read and nearly 1.6GB/s write! While these results do not show perfect scaling, they are quite impressive.
