OCZ Z-Drive R4 PCIe SSD Performance Preview
PCMark Vantage HDD
This series of Vantage tests will stress mostly read performance in pseudo real-world usage models, with a mix of sequential and random read transactions of both small and large file sizes.
The OCZ Z-Drive R4 performs well in this first group of PCMark Vantage HDD tests, but it doesn't quite lead the pack as one might expect. It was only in the Windows Defender test that the Z-Drive takes the lead; in the other three tests the Z-Drive R4 trails at least one of its competitors and in two of the tests even the RevoDrive 3 X2 is faster.
