Corsair Neutron 240 GB vs. OCZ Agility 4 256 GB SSD Review
Compressible Data Test
Contents
As you will have gathered from the previous page, we measured the performance of each drive using two different programs: CrystalDiskMark and Iometer.
It’s important to note that we connected the SSDs to a SATA-600 port on our motherboard rather than a SATA-300 port, which could cause performance limitations.
We set CrystalDiskMark to “All 0x00 Fill mode” to evaluate the performance of the SSD when dealing with compressible data.
In the sequential read test, the Corsair Neutron achieved 22 percent better performance than the OCZ Agility 4. However, in the sequential write test, the OCZ Agility 4 performed the best, beating the Corsair Neutron by 11 percent.
Moving on to the random read test using 512 kB blocks, the Corsair Neutron offered the best performance, beating the OCZ Agility 4 by 81%. However, in the random write test using 512 kB blocks, the OCZ Agility 4 beat the Corsair Neutron by 11%.
In the random read test using 4 kB blocks, the Corsair Neutron beat the OCZ Agility 4 by 25 percent. However, in the random write test using 4 kB blocks, the OCZ Agility 4 beat the Corsair Neutron by a margin of 56 percent.
