OCZ Z-Drive R4 PCIe SSD Performance Preview

Article Index:   

Our Test Methodologies: Under each test condition, the SSDs tested here were installed as secondary volumes in our testbed, with a standard spinning hard disk for the OS and benchmark software installations. The SSDs were left blank without partitions wherever possible, unless a test required them to be partitioned and formatted, as was the case with our ATTO, Vantage, and CrystalDiskMark benchmark tests, as well as one of the IOMeter runs. Windows firewall, automatic updates and screen savers were all disabled before testing. In all test runs, we rebooted the system and waited several minutes for drive activity to settle before invoking a test.

CrystalDiskMark v3.1
PCMark Vantage
SiSoftware Sandra 2011
HH Custom File Transfer Tests

SiSoft SANDRA 2011
Synthetic HDD Benchmarking

For our first set of tests, we used SiSoft SANDRA, the the System ANalyzer, Diagnostic and Reporting Assistant. Here, we used the Physical Disk test suite and provided the results from our comparison SSDs. The benchmarks were run without formatting and read and write performance metrics are detailed below.



What can we say that this benchmark results chart doesn't already?  In the quick-take sequential transfer measurements that SANDRA pushes to the SSDs in our test run, the Z-Drive R4 is over two time faster than the Fusion-io ioDrive in both read and write throughput.  The only drive that comes close to the R4 is the OCZ RevoDrive 3.  That's what you call a happy performance graph.
