ATTO Disk Benchmark 3.0.2 Results

ATTO is one of the oldest benchmarks around, but it’s still a useful tool to gauge a drive’s adeptness at managing compressible data. It’s also useful for seeing how a drive performs across a variety of different transfer block sizes. Unsurprisingly, the Samsung SSD 950 Pro was the quickest drive, across all data block sizes. Over larger 512K and 8MB data blocks, the Samsung SSD 950 Pro’s read speeds were close to 50% faster than the fastest SATA-based SSD, whereas write speeds were a more modest 32% or so quicker. But it’s on smaller 4K data blocks that the SSD 950 Pro really showed its prowess, its read and write speeds were both over 50% faster.
