MyDigitalSSD SBX 512GB NVMe SSD Review

ATTO & CrystalDiskMark

ATTO v3.05

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.

ATTO – MyDigitalSSD SBX M.2 512GB:

Benchmark Results: ATTO Disk Benchmark had the MyDigitalSSD SBX 512GB M.2 PCIe NVMe drive reaching speeds of up to 1,781 MB/s read and 1,045 MB/s write in the standard overlapped I/O benchmark. Really strong results from a budget friendly TLC NAND Flash drive!

Benchmark Results: Compared to some other SATA III and PCIe NVMe SSDs, the MyDigitalSSD SBX 512GB drives sequential write performance was okay.

Benchmark Results: The ATTO sequential write performance on the MyDigitalSSD SBX hit 1 GB/s at 32KB and pretty much flat lined there.

CrystalDiskMark 6.0.0 x64

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.

CystalDiskmark – MyDigitalSSD SBX M.2 512GB:

Benchmark Results: The MyDigitalSSD SBX 512GB SSD topped out at 1615.1 MB/s read and 1045.3 MB/s write in the standard sequential write test that is done at QD32. Random 4K QD1 performance was 40.61 MB/s read and 106.0 MB/s write. Really impressive performance numbers here!
