CrystalDiskMark is a disk benchmark software that allows us to benchmark 4K and 4K queue depths with accuracy.
Key Features:-
* Sequential reads/writes
* Random 4KB/512KB reads/writes
* Text copy
* Change dialog design
* internationalization (i18n)
Note: Crystal Disk Mark 3.0 Technical Preview was used for these tests since it offers the ability to measure native command queuing at 4 and 32.
In CDM we get our first look at incompressible data performance. The Agility 4 has a slight drop off of performance when working with incompressible data, something we'll see when looking at the Anvil Benchmark data further down in this review.
For now let's focus on 4K and NCQ performance. The Agility 4 achieves a 22MB/s read 4K QD1 speed, but ramps up in a linier fashion to QD4, nearly 80MB/s. At 32 depth we hit just over 266MB/s. These are solid performance numbers especially from a drive using asynchronous flash.
Write performance in everything other than the sequential and 512kb test nearly mirrors what we achieved on the Vertex 4.
