CrystalDiskInfo is free benchmark that many people use to test storage drives with, but this test runs really quick and the results show the highest score of the five ‘burst’ tests for each performance metric tested. The problem is that the tests are so small and quick it rarely ever fills up a drives cache and is not a good look at real world performance on many external drives or SSDs that use TLC NAND Flash memory. We are including results for you to look at as you can use it at home to compare with to get an idea what the best case performance looks like on this drive.
We managed to hit 456.9 MB/s on the sequential read and 458.2 MB/s on the sequential write test, which are pretty solid scores from the external SSD. The WD My Passport 4TB external hard drive has a 5400 RPM hard drive inside and only managed to reach 118.5 MB/s on the sequential read and 112.7 MB/s on the sequential write test, so there is greater than a 3x performance difference in sequential performance between the two models.
ATTO Disk Benchmark showed that we were getting up to 483 MB/s read and 479 MB/s write speeds as well, so it looks like the WD My Passport SSD 1TB portable drive has some solid performance numbers.
With the applicactions preset in Anvil’s Storage Utilities we found sequential speeds of up to 447 MB/s Read and 440 MB/s Write!
We wanted to do some real world file transfers, so we copied over few MKV Full-HD movie that added up to almost 6GB. During the transfer we found that we were getting around 285-340 MB/s on average when the data was being written to the My Passport SSD 1TB drive. Real world performance is going to be lower than the peak numbers shown in the ATTO and CrystalDiskMark benchmarks, but it still isn’t bad!
Let’s wrap this up!
