IO Meter IOPS performance
New in our tests is IO meter. We brought the ancient application back in rotation as it remains to be the best application to really stress the Random IO performance amongst others of storage devices.
Iometer is a workload creator, it will literally perform massive I/O operations in order to stress the system. To measure random I/O response time as well as total I/O's per second, Iometer is set to use 4KB file size chunks and will completely trash the SSD with random 4KB files, massively stressing the random IO.
We apply our own 4KB Random IO read and write stress test, leave it running for 3 minutes and then note down the average IOPS score in operations per second.
First off read performance. We have very few results as this is a recently added application. If you look at the top three, really good performance.
Now with Random IO 4KB WRITE performance the ball changes completely ... this is EXACTLY where the SandForce controllers kick massive ass, Random IO writes. Both the Corsair P128 (Samsung controller) and original Vertex (Indilinx) run into roughly 2000 operations per second. All the way at the bottom we see the Silicon Power M10 SSD with JMicron controller (no cache memory) merely 500 write IOPS/sec.
And then look at the new Vertex 2 .. it's nearly six to seven times faster than the Indilinx products at this particular feature.
Reference screenshot of how we test
In this article we test, benchmark and review the OCZ Vertex 3.20 SSD. What a great and fast piece of technology this is. An 20nm NAND flash SSD that is speedy and actually amongst the the rest of the devices tested, but also mroe affordable. Head on over into the review.
OCZ Vertex 4 SSD review with 1.5 firmware
We retest the OCZ Vertex 4 SSD yet now with 1.5 firmware update. , again bringing more performance towards the Vertex 4 series of SSDs. And albeit the difference is not as big as the 1.4 release was, it certainly makes a difference as this article will show you.
OCZ Vertex 4 SSD revisited with FW 1.4RC review
We revisit the OCZ Vertex 4 256 and 512GB SSD review, this time with Firmware 1.4 which makes the drives much faster. Armed with a new Indilinx Everest 2 controller this SSD is advertised as one of the fastest on the block with screaming IOPs performance. Lets have a look shall we ?
