Testing – Anvil, PCMark Vantage & AIDA64
The next test is Anvil Storage Utilities, which is a really great piece of software. The SSD benchmark gives you scores for both read and write as well as a combined score.
We also use Anvil to test IOPS. The Threaded Read and Write tests are great for this. On each one we set the QD to 32.
We have now added PCMark 8 to our solid state drive benchmarks. We will be running the typical Storage Benchmark.
We have also added back AIDA64’s Disk Benchmark to our testing. The linear tests will actually scan from the first physical sector to the last on the test drive. This gives a good representation of sustained read / write operations. We will be running the linear read and write tests using a 1MB block size.
The write test will shows that SLC caching is being utilized. You can see while that drive starts out the write test at around 475 MB/s it drops down to around 106 MB/s. You will see this lower speed if you copy a large amount of data to the drive without any idle time. This is typical of TLC-based solid state drives. The cache on the drive will clear once the drive idles so this will only affect writes that are many GB’s in size. You should not see lower write speeds when doing typical transfers of small files.
