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: On ATTO Disk Benchmark we see that the Patriot Viper VPR100 1TB drive reached speeds of up to 3.02 GB/s read and 2.80 GB/s write at a Queue Depth of 4.
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 Patriot Viper VPR100 RGB 1TB drive maxed out at 3406.98 MB/s read and 3028.40 MB/s write in the standard sequential write test that is done at Q8T1. Random 4K performance topped out at 423,600 IOPS read and 372,400 IOPS write. This drive is rated at 700,000 IOPS read and 650,000 IOPS write, so we are off just a bit on the 4K random write numbers.
