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.
SYSTEM COMPONENTS
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. Also, a big thank you to Thermaltake for the case 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!

BENCHMARK SOFTWARE
The software in use for today’s analysis is typical of many of our reviews and consists of Crystal Disk Info, TRIMcheck, ATTO Disk Benchmark, Crystal Disk Mark, AS SSD, Anvil’s Storage Utilities, PCMark Vantage, and PCMark 8. 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.
Crystal Disk Info is a great tool for displaying the characteristics and health of storage devices. It displays everything from temperatures, the number of hours the device has been powered, and even to the extent of informing you of the firmware of the device.
In Crystal Disk Info, we can see that SMART is supported and there are quite a few useful metrics one can monitor, including total host reads and writes, temperature, and more. The firmware we are testing today is PSF100C.
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.
As can be seen in the screenshot above, TRIMcheck’s result is Intermediate. This means it cannot determine if TRIM was in fact working, but it does not mean that it won’t kick in at all.
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’s results look good from file sizes 0.5KB to 8MB, but after that performance tanks to just about 200-300MB/s, which is quite strange compared to what we typically see. The best performance results in this test were at about 1.89GB/s read and 565MB/s write, however.
Passed my first test-At least 8K-IOPS-QD1.
Failed my second-Must write 200+ after buffer
can’t have it bottleneck my spinning rust.
Write speed shocked me for a 500 size drive
those speeds you expect on a 120 size drive.
And why the SLC cache so small???????
The ATTO results make sense as the 600p doesn’t have a controller that supports direct to die algorithm to relieve the bottle neck that occurs once the SLC cache is full. That being said very few program reads, go above 128K in windows. So, everything past that is just large file transfer, and really inconsequential in day to day compute performance outside of OS install.
