ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. The test was run with the default runs of 0.5KB through 64MB transfer sizes with the total length being 256MB.
Benchmark Results: ATTO showed thCrucial BX300 480GB drive reaching speeds of up to 564 MB/s read and 529 MB/s write in the standard overlapped I/O benchmark. This drive is rated at up to 555 MB/s max sequential read and 510 MB/s max sequential write, so we exceeded both of those scores on our test platform.
Benchmark Results: Compared to some other SATA III SSDs we can quickly see that there isn’t much difference with regards to sequential read performance. The Crucial BX200 didn’t do too hot in the sequential write test, but the BX300 was notably better. When it comes to small file transfers almost all SATA III SSDs perform the same., so nothing too exciting here.
CrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds. 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.
Benchmark Results: The Crucial BX300 480GB drive reached 563MB/s read and 526 MB/s write in the standard sequential write test. Random 4K QD1 performance was 34 MB/s read and 109 MB/s write. Those numbers improved up to 223 MB/s read and 203 MB/s write at a queue depth of 32.
