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 760p 512GB PCIe NVMe drive reaching speeds of up to 3079 MB/s read and 1621 MB/s write in the standard overlapped I/O benchmark. Intel has this drive rated at up to 3230 MB/s max sequential read and 1625 MB/s max sequential write, so we came up just shy of those numbers on our Intel Z370 based test platform.
Benchmark Results: Now that we have added more PCIe NVMe drives that we add to the chart, the SATA III drives are pretty much globbed into a single flat line as they all top out at around 550-563 MB/s. The Intel SSD 760p 512GB drive is faster than the Intel SSD 600p 512GB drive at every block size tested, so the winner between those two drives is clear. The Intel SSD 760p 512GB drive was performing close to the Sasmung SSD 960 EVO 250GB drive at most block sizes!
Benchmark Results: Once again the Intel SSD 760p massively out performs the Intel SSD 600p and was close to the Samsung 960 EVO series at all block sizes except 16KB.
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 760p 512GB maxed out at 3206 MB/s read and 1607 MB/s write in the standard sequential write test that is done at QD32. We are so close to the drives rated speeds of 3230 MB/s read and 1625 MB/s write, but just can’t manage to reach them! Random 4K QD1 performance was 73.2 MB/s read and 205.1 MB/s write. Those 4K random performance numbers improved up to 444 MB/s read and 380 MB/s write at a queue depth of 32. This drive is hauling!
Manually running the sequential performance test at Q1T1 showed performance of 2166 MB/s read and 1588 MB/s write.
If you chart those numbers against some of the drives we have recently tested you’ll see the Intel SSD 760p has higher QD1 performance than the more expensive Intel Optane SSD 800P 118GB drive. In fact, it is even faster on QD1 sequential reads than the flagship Intel Optane 900P 480GB drive. Amazing!
Let’s look at some other benchmarks!
