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 the Intel SSD 545s 512GB drive reaching speeds of up to 563 MB/s read and 506 MB/s write in the standard overlapped I/O benchmark. This drive is rated at up to 550 MB/s max sequential read and 500 MB/s max sequential write, so we exceeded both of those scores on our test platform.
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 Intel SSD 545s 512GB drive reached 532MB/s read and 481 MB/s write in the standard sequential write test and Random 4K performance was 48 MB/s read and 110 MB/s write. The Sequential Q32T1 performance was at 562 MB/s read and 507 MB/s write, which is over drives rated sequential values of 550 MB/s read and 500 MB/s write on CrystalDiskMark. When we ran the test again set to 0Fill mode the sequential read scores were mostly in the same ballpark.
Let’s look at some other benchmarks!
