For testing, the drives are all wiped and reset to factory settings by HDDerase V4. We try to use free or easily available programs and some real world testing so you can compare our findings against your own system. This is a good way to measure potential upgrade benefits.

We are in the process of updating our testing procedures for NVMe SSDs, adding new tests, refining others and using the latest versions of CrystalDiskMark, ATTO and AS SSD benchmarks. For a time we will show both old and new screenshots of these benchmarks as we transition from the older tests to the newer ones. We will try and re-test as many of the previously reviewed NVMe drives as we can so as to build up new versions of our comparative performance graphs.

The test setups for the new tests are listed below. Each test is run five times.

128KB Sequential Read / Write.
Transfer Request Size: 128KB Span: 8GB Thread(s): 1 Outstanding I/O: 1-32 Test Run: 20 minutes per test

4K Sustained Random Read / Write.
Transfer Request Size: 4KB Span: 80GB Thread(s): 4 Outstanding I/O: 1-32 Test Run: 20 minutes per test

4K Random 70/30 mix Read/Write.
Transfer Request Size: 4KB Span: 80GB Reads: 70% Writes: 30% Thread(s): 4 Outstanding I/O: 2 – 32 Test Run: 20 minutes

Main system:
Intel Core i7-7700K with 16GB of DDR4-3200 RAM, Sapphire R9 390 Nitro and an Asus Prime Z270-A motherboard.

All our results are achieved by running each test five times with every configuration to ensure that any anomalies are removed from the results. TRIM is confirmed as running by typing ‘fsutil behavior query disabledeletenotify' into the command line. A response of ‘disabledeletenotify =0' confirms TRIM is active.
