WD Blue 2TB Hard Drive WD20EZRZ 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 – WD Blue 2TB HDD:

Benchmark Results: ATTO showed the WD Blue 2TB drive reaching speeds of up to 167 MB/s read and 154 MB/s write in the standard overlapped I/O benchmark.

Benchmark Results: We were a bit shocked to see the WD Blue 2TB hard drive beating some of the SSDs on the smallest transfer sizes, but that was short lived and then the performance gap became a mile wide.

Benchmark Results: There is only so much performance one can expect from a hard drive since it’s spinning media!

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 – WD Blue 2TB HDD:

Benchmark Results: The WD Blue 2TB 5400 RPM drive topped out at 164 MB/s read and 157 MB/s write in the standard sequential write test that is done at QD32. Random 4K QD1 performance was 0.6 MB/s read and 1.9 MB/s write.

Let’s look at some other benchmarks!
