OCZ Vector 256GB SSD Review

ATTO Disk Benchmark is an old and simple but still very popular synthetic benchmark used to test the maximum theoretical speed of any storage devices, from RAID controllers and host adapters to HDD and SSD drives.

Being a synthetic benchmark, ATTO only displays the maximum possible speeds a drive may achieve when handling specific strings of data; in our case, compressible 512KB-4096KB packages. This is a good benchmark to examine if the performance of a drive is on par with the manufacturer’s specifications. OCZ claims that the Vector can reach a read speed of 550MB/s and a write speed of 530MB/s; we were not let down, with the drive reaching speeds up to 557.6MB/s read and 535MB/s write.

 

CrystalMark 3.0 x64 is another simple but popular synthetic benchmark used to measure the maximum theoretical speed of hard disk and solid state drives.

The 0x00 fill mode (compressible) mode of the test should confirm the results of the ATTO benchmark, yet the write performance of the drive dropped notably during this test. On the other hand however, the Vector remains just as fast when handling incompressible data as well, indicating that the Indilinx Barefoot 3 controller does not heavily depend on compression algorithms for performance, allowing it to perform very well even when the data cannot be compressed. Drives with controllers which relied on compression algorithms, such as the now-aged Agility 3, take a massive performance hit when invited to handle real-world data.
