OCZ Technology Vector 128GB SSD RAID Report - Benchmarks - Test System Setup and ATTO Baseline Performance

OCZ Technology Vector 128GB SSD RAID Report

OCZ's Vector 128GB is one of the highest performing drives on the market today in RAID 0. Now at under $1 per GB, it could be a setup to consider. (NASDAQ:OCZ)

This will be the last RAID Report before we move to the new Haswell systems.

Intel is the only company that we know of that is able to pass the TRIM command to a RAID pair of drives. We gave the array a 10% overprovision and used a data stripe size of 16KB.

 

Larger stripe size gives better sequential performance and a smaller stripe size gives better random performance. For the onboard Intel RAID, 16KB is a good choice for general use.

 

 

ATTO Baseline Performance

 

Version and / or Patch Used: 2.34

 

Many manufactures use ATTO to determine the read and write speeds that are used in marketing document and for comparison.

In ATTO we managed to surpass 1000 MB/s (1 GB/s!) when reading data on the two drive RAID 0 array.

 

Write performance was over 400 MB/s in ATTO, but we expected more since that is what a single Vector 128GB achieves.
