Samsung 950 Pro M.2 NVME SSD Review (256/512GB) – The NVMe Effect

CRYSTAL DISK BENCHMARK VER. 3.0.3 x64

Crystal Disk Benchmark is visually straightforward, and is used for measuring the speeds at which your storage device reads and writes in both compressible (oFill/1Fill) and random, mostly incompressible, data. Random data is more consistent with everyday use of a computer, such as transferring videos, pictures and music. We run the benchmark twice, using oFill data first, and then proceeding to test with random data. Since results typically return with nearly identical scores, we only include the results for random data samples.

While the Crystal Diskmark result of the 512GB 950 is dead on, that of the 256GB version is a bit surprising as the high sequential read result of 2.302MB/s is well above the specification listed 1500MB/s. As well, it is great to see low 4K random write performance above 200MB/s finally become commonplace with SSDs.

AS SSD BENCHMARK VER. 1.7

AS SSD Benchmark uses incompressible data in their testing of SSDs, essentially providing results that would be consistent with using the heaviest workload, thus lower speeds are expected.

Checking out the Copy Benchmark below, it is pretty remarkable that, in both tests, the ISO file was transferred in 6/10ths of a second.

ANVIL STORAGE UTILITIES PROFESSIONAL

Anvil Storage Utilities is essentially an all-in-one tool for all of your SSD benchmarking needs. Anvil can be used for basic consumer testing, as well as endurance testing and threaded I/O read, write and mixed tests. It displays data regarding the SSD, and even about your system.

We thought we might get a bit deeper into Anvil Storage utilities and did a few custom tests where we saw much better IOPS.

We are only displaying that of the 512GB, however, the 256GB version fairly well and attained 279K IOPS read and 76K IOPS write.
