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 Disk Benchmark showed the Kingston A2000 1TB SSD reaching speeds of up to 2.08 GB/s read and 2.03 GB/s write at a Queue Depth of 4. This is slightly below the drives rated sequential read/write speeds of 2200/2000 MB/s.
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 Kingston A2000 1TB drive topped out at 2271.01 MB/s read and 2,161.60 MB/s write in the standard sequential write test that is done at Q8T1. Random 4K Q1T1 performance was 38.39 MB/s read and 54.90 MB/s write.
This drive is rated at being up to 2,200 MB/s read and 2,000 MB/s write. We were able to hit both those numbers on one benchmark!
