TSSDR TEST BENCH AND PROTOCOL
SSD testing at TSSDR differs slightly, depending on whether we are looking at consumer or enterprise storage media. For our WD Black AN1500 NVMe RAID Card SSD testing today, 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, and Enhanced Intel SpeedStep Technology (EIST) has been disabled.
The components of this Test Bench are detailed below. All hardware is linked for purchase and product sales may be reached by a simple click on the individual item. As well, the title is linked back to the individual build article where performance testing can be validated.

The software in use for today’s analysis is typical of many of our reviews and consists of Crystal Disk Info, ATTO Disk Benchmark, Crystal Disk Mark, AS SSD, Anvil’s Storage Utilities, AJA, and TxBench. 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.
Other than confirmation that we were running in PCIe 3.0 x8 mode, a few things were really obvious in this Crystal DiskInfo result. TRIM is not mentioned as it would normally be, although it seems to work fine through the WD Dashboard. Also we would like to get an idea of host reads and writes through this software. Our question might be that if it is not recognized here, how could WD enforce the 600TBW/TB rating. Last but not least, the WD Black AN1500 runs a bit hot levelling off at 61°C. We have installed this SSD as our system SSD in one of our benches and will revisit temperature if anything becomes concerning.
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.
Listed specs are 6.5GB/s read and 4.1GB/s write while ATTO shows us 6.5GB/s read and 4.9GB/s write.
