It is a memory benchmarking programme for Mac OS X that uses CrystalDiskMark's user interface. It is a port of CrystalDiskMark for Mac OS X, published by Katsura Shareware, developed by Twitter user polydron. Other features include Intel RAID support, e-mail and sound warnings, and AAM/APM adjustment. Like CrystalDiskMark, this tool is designed with an emphasis around solid state devices, supporting NVMe connections in addition to the usual PATA and SATA. utility for reading and monitoring disk drive status. Random 4K QD1 performance was 0.6 MB/s read and 1.9 MB/s write.English, Japanese, Russian, Chinese, etc.ĬrystalDiskInfo is an MIT-licensed S.M.A.R.T. CystalDiskmark – WD Blue 2TB HDD:īenchmark Results: The WD Blue 2TB 5400 RPM drive topped out at 164 MB/s read and 157 MB/s write in the standard sequential write test that is done at QD32. Note that CDM only supports Native Command Queuing (NCQ) with a queue depth of 32 (as noted) and shows the highest score of five runs. ATTO – WD Blue 2TB HDD:īenchmark Results: ATTO showed the WD Blue 2TB drive reaching speeds of up to 167 MB/s read and 154 MB/s write in the standard overlapped I/O benchmark.īenchmark Results: We were a bit shocked to see the WD Blue 2TB hard drive beating some of the SSDs on the smallest transfer sizes, but that was short lived and then the performance gap became a mile wide.īenchmark Results: There is only so much performance one can expect from a hard drive since it’s spinning media! CrystalDiskMark 6.0.0 圆4ĬrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds.
The test was run with the default runs of 0.5KB through 64MB transfer sizes with the total length being 256MB.
It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. ATTO measures transfers across a specific volume length. ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world.
