WD Blue SN550 1TB ASSSD 1GB WD Blue SN550 1TB ASSSD 1GB Chart Like other utilities, it was run with both the default 1GB as well as a larger 10GB test set. AS SSD BenchmarkĪS SSD Benchmark is another good benchmark for testing SSDs. With 8GB test size, there is a very minor dip in the results relative to the 1GB results, but not much. WD Blue SN550 1TB Anvil 8GB WD Blue SN550 1TB Anvil 8GB Chart In terms of relative performance though, the WD Blue SN550 1TB has a better result here than in some of the previous benchmarks. With Anvil running a 1GB test size, the read speeds are lower than with CDM or ATTO, while the write speeds remain higher. WD Blue SN550 1TB Anvil 1GB WD Blue SN550 1TB Anvil 1GB Chart This benchmark was run with both a 1GB and 8GB test size. Anvil’s Storage UtilitiesĪnvil’s Storage Utilities is a comprehensive benchmark that gives us a very in-depth look at the performance of drives tested. In the positive column for this drive is that, once again, the larger test set has no negative impact on performance the ATTO 8GB test set is nearly indistinguishable from the 256MB one. WD Blue SN550 1TB ATTO 8GB WD Blue SN550 1TB ATTO 8GB Chart Unlike CrystalDiskMark, the drive comes in slightly below the advertised performance rather than slightly above. Similar to CrystalDiskMark, ATTO performance is close to the advertised specs and in no way competing for the high end of NVMe drive performance. WD Blue SN550 1TB ATTO 256MB WD Blue SN550 1TB ATTO 256MB Chart ATTO was tested at both 256MB and 8GB file sizes. The ATTO Disk Benchmark has been a staple of drive sequential performance testing for years. WD Blue SN550 1TB CrystalDiskMark 8GB ChartMoving to the 8TB test set has a negligible impact on the WD Blue SSD, which is encouraging. With that said, this drive is obviously targeting middle-of-the-road performance overall. Using the 1GB test set, the WD Blue SN550 1TB is right on target and slightly exceeding the advertised 2400 MB/s read and 1950 MB/s write specs. WD Blue SN550 1TB CrystalDiskMark 1GB WD Blue SN550 1TB CrystalDiskMark 1GB Chart CrystalDiskMark 7.0.0 圆4ĬrystalDiskMark is used as a basic starting point for benchmarks as it is something commonly run by end-users as a sanity check. Some previously tested QLC-based PCIe 3.0 SSDs do not pass all these tests, and no SATA based drive can do so. WD Blue SN550 1TB BlackmagicĪs a PCIe 3.0 NVMe SSD, the WD Blue SN550 1TB has a good showing here and handles every format this benchmark can test for. It shows whether a storage device is suitable for throughput required at a given video format. This is a popular speed test in the video community. Unfortunately, our entire backlog of SSD reviews did not include this testing methodology, so we are doing the best we can with generating comparison charts. This allows us to see the difference between lighter and heavier workloads. We are moving towards using larger test sizes on our benchmarks, but on several tests, we also used the smaller default test sizes.
