Angelbird SSD wrk 256GB SSD Review – Silicon Motion SM2246EN

ATTO & CrystalDiskMark

ATTO v2.47

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 8192KB transfer sizes with the total length being 256MB.

ATTO – Overlapped I/0:

Benchmark Results: ATTO showed Angelbird SSD WRK 256GB drive maxing out at 563 MB/s read and 299MB/s write in the standard overlapped I/O benchmark. This drive is rated at having up to 563MB/s read and 297MB/s write, so it looks like Angelbird was spot on with their performance specifications.

CrystalDiskMark 3.0.3 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) for the last listed benchmark score. This can skew some results in favor of controllers that also do not support NCQ.

Benchmark Results: The Angelbird SSD WRK 256GB drive scored 547MB/s read and 298MB/s write on the sequential test when we ran the drive on the CrystalDiskMark storage test with the default settings. The 4K scores were just shy of 33MB/s read and were right around 138MB/s for the write speed. We also ran the 0Fill test and found that the sequential and random read/write performance of the drive remained the same.
