Benchmarks: CrystalDiskMark 3.0

The Agility 4 has a claimed sequential read speed of 420MB/due south, but it fell brusk of that figure in CrystalDiskMark, reaching 353.4MB/s, while the Crucial v4 beat its quoted speed of 230MB/s, hitting 246.1MB/s. Despite exceeding its listed specs, the v4 was yet 44% slower than OCZ's drive.

With a write speed of 408.5MB/s in CrystalDiskMark, the Agility four fell just shy of its quoted rate of 410MB/s, merely it was notwithstanding fast plenty to beat everything except the Vertex 4. As we saw in the read test, Crucial's offering performed meliorate than expected, beating its claimed write speed of 190MB/southward with 222.2MB/s. All the same, the v4 was still slightly slower than the Patriot Torqx ii, Crucial RealSSD C300 and Intel SSD Serial.

When measuring random 512K reads, the Agility 4 was 18% faster than the v4, which is one of the smaller margins that we take seen and then far. All the same, random 512K reads were a weakness of the Vertex iv, then we expected no meliorate of OCZ's upkeep solution.

The Agility 4 looked adept when measuring random 512K writes, losing only to the Vertex 4 and outpacing the v4 by 134%.

The Agility 4 was surprisingly stiff when measuring random 4K-QD32 performance, sustaining a throughput of 248MB/southward, on par with the pricier Vertex four. The v4, on the other hand, was 74% slower, achieving a throughput of just 64.6MB/southward.

Equally we've seen already, write operation is where the Agility 4 flourishes and it managed to achieve 203.5MB/s in CrystalDiskMark's Random 4K-QD32 write examination, but 12% slower than the Vertex iv and 514% faster than the v4'southward dismal 33.1MB/south.
