If your benchmark results don't line up with what the manufacturer said you should be getting, or your performance is way off from what the average reported PassMark performance for the SSD is listed as, then try reseating the SSD. Are they in line with each other? If not, it could be an issue with compatibility, heat throttling, or a cluttered SSD, but if your score is considerably lower, then check to make sure that you've installed the SSD in the right slot and that there weren't any severe temperature spikes during testing. Once you've found it, compare your PassMark Disk score to the average score for that SSD. Compare your results with the manufacturer's listed speedsĪssuming that your sequential read and write performance is what you expected, navigate to PassMark's database of Disk Benchmark scores.ĬTRL+F your SSD's model name to find it on the list (making sure to also find the same drive capacity, as different capacities can perform very differently). Note these scores and run the test two more times and average the results. The other results are important, but the only one I would make a note of is the third row labeled 'RND4K,' which gives the SSD's Random Read and Random Write performance. The top row is the Sequential Read and Sequential Write scores, given in MB/s, and it's these scores we're most interested in. There might be wildly varying scores at first, and if so, you can run the test a few more times until the test results start becoming more consistent, then take the three scores and average them.įor CrystalDiskMark, click the top-left button that says 'All' to run the read and write tests. Once the test is finished, run it two more times and average the three scores to get your final score. You can run other benchmarks or all of them in one go if you'd like, but we're only interested in the Disk test. Now that you're ready to benchmark your SSD, open up the two benchmarking tools if you haven't already.įor PassMark's Performance Test, you'll want to click the 'Run' label on the bottom of the Red Panel in the testing interface. Crystal Dew World / PassMark Software / Future) This number will be around 70C / 160F in many cases, but check with your manufacturer. This is the usually the ASIC controller in the SSD, the part that actually coordinates the read/write/copy operations and it's the part that's most sensitive to heat damage, so you'll want to keep an eye on it.ĭuring testing, if the temperature approaches the maximum safe temperature for the drive provided by the manufacturer, you'll probably need to reseat the SSD with better contact with the M.2 SSD slot's heatsink. Make note of the maximum temperature column and find Drive Temperature 2 on the list. For a new SSD, this should be 100%, so if it's lower than the drive might be defective or previously used. Note the Total Remaining Life percentage in the S.M.A.R.T. In the sensor list, scroll down until you find the SSD you want to benchmark, which should be prefixed with the label 'S.M.A.R.T.' and a second set of readings under the label 'Drive:'. ![]() This will open up the Sensor Status screen, which you can move off to the side of your desktop, but leave it visible. Find the one labeled 'Sensors' and click on it. In HWiNFO's main window, you'll see a number of buttons along the top ribbon. Likewise a PCIe 5.0 SSD in a PCIe 4.0 slot.įor SATA III SSDs, any modern motherboard will only have SATA III ports, but for the odd ducks out there, make sure you're using the properly rated interface for your SSD regardless. ![]() If you are using a PCIe 4.0 or PCIe 5.0 SSD, make sure that the interface for the SSD in the bottom left of the System Summary panel matches the SSD's rated speed.Ī PCIe 4.0 SSD will run in a PCIe 3.0 slot, but its speed is going to be greatly reduced. There is going to be a lot of information suddenly on the screen, but the only thing we're interested in is making sure that the SSD is plugged into the right slot on the motherboard or SATA port. When you see the small popup window on launch, press start to open up the system information panel. Once you've downloaded and run an antivirus scan on the installer and its confirmed safe, install the tool wherever you'd like, but make sure to launch it after it finishes installing. Head over to the HWiNFO download page and grab the Windows installer for this tool, which we'll use to check drive health and monitor our SSD temperature during testing.
