OCZ has listed specifications of the Z-R4 at an amazing 440,000 IOPS at 4K-QD128 (8GB LBA) so we decided it only fair to recreate this exactly. With the test file at 8GB, results will be obtained without cache leverage. For the test procedure, we set IOMeter up with two managers, each manager having two workers and wanted to take advantage of the Intel i7-2600 as it is a multi-core processor. Four workers would be working simultaneously which would require the use of four cores.
OCZ Z-DRIVE R4 1.6TB PCI EXPRESS SSD
Although we didn’t quite reach 440,000 IOPS, we have to admit that reaching 414,515 IOPS was something else. Pushing it this hard also required additional precautionary fans strategically placed around the card to keep her happy. This round was a tough call as the Z-R4 was clearly the winner in its transfer speed of 1697MB/s while the io-D was the clear victor in its speedy IO Response time of 5ms. The decision went to the Z-R4 though as 414,515 IOPS simply cannot be overlooked.
From a personal perspective, I can just imagine testing this card with two SuperScale Storage Controllers configured which changes its specs to over 5GB/s read and write with well over a million IOPS! Hey OCZ… we think there needs to be such a test done!
ANVIL STORAGE UTILITIES MIXED TESTIING
We thought it only fair to do a bit of testing in Anvil to see if we could find a specific benchmark that really set these drives apart. We found that in mixed read/write tests at 4k-QD64 and we believe that you might even agree that the Z-R4 truly shined in this specific benchmark:
