Crucial BX200 480GB SATA 2.5-Inch 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 – Overlapped I/O:

Benchmark Results: ATTO showed Crucial BX200 480GB drive maxing out at 558 MB/s read and 498 MB/s write in the standard overlapped I/O benchmark. Crucial rates the BX200 480GB drive as having up to 540 MB/s read and 490 MB/s write with regards to sequential performance, so it looks like those ratings are ever so slightly conservative. The sequential write performance dropped unexpectedly at the 24MB and 48MB file sizes and we don’t have an answer as to why that happened unless the cache filled up for some reason in those two instances. 

CrystalDiskMark 5.0.2 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 Crucial BX200 480GB drive topped out at 538 MB/s read and 481 MB/s write on the sequential test when we ran the drive on the CrystalDiskMark storage test with the default settings. The 4K scores were 32 MB/s read and 132 MB/s for the write speed. The incompressible data test is representative for the performance you’ll see when moving around movies, music and photographs. We also ran the 0Fill test and found that the sequential and random read/write performance of the drive essentially remained the same.

Let’s look at some other benchmarks!
