OCZ RevoDrive 3 X2 review

IO Meter IOPS performance
IO meter, results vary per website since everybody configures this test differently. We brought the ancient application back in rotation as it remains the best application to really stress the random IO performance amongst others for 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 so it differes a little from OCZ's own test methodology, we leave it running for a while and then note down the average IOPS score in operations per second.
Above read performance - again really good performance right there. Roughly 165K IOPS which is just sick. The CPU usage was a little high during this test (Core i7 2600K processor), but this test is so immense it could kill off a mid-range system really.
Above write performance - Now with Random IO 4KB WRITE performance, this is where SandForce controllers kick massive ass. It seems that everybody is using IOMeter's parameters slightly different, but that is more than I expected.
Also and I really need to say this, we feel IOMeter is just a horrible test. There's no application in this worlds that continuesly writes perfect 4K files all of the time. The test was designed to show high numbers for SSD technology and as such we start to dislike it more and more, as it does not say a thing about actual real-world performance. What this test needs to become more objective are random file/block sizes reading and writing.
AS SSD Benchmark
Added to the benchmark suite is this nice little German application called AS SSD Benchmark. This test gives an extensive result set. The test is popular, but probably not the best one out there. So just for reference, here we go.
Now we left the unit for 20 minutes in idle, and ran the test again.
Nothing to compare to yet, but we did ran some other tests with other SSDs and performance is up-to speed alright.
We review the RevoDrive Hybrid. The idea behind the device hints very much towards Intel's Rapid Storage technology where a HDD is being cached by a Nand flash storage unit. Being OCZ they are making it an enthusiast class performance product. The product we test today for example comes with a 1TB HDD, and a really large 100GB cache partition running over SF2281 controllers. OCZ then applies a mix of their VCA 2.0 technology
OCZ RevoDrive 3 X2 review
We'll be testing an engineering sample of that RevoDrive 3 X2 today. Let me just throw some numbers at you to get that tickly in your belly ; 1500 MB/s maximum read performance, or what about 1250 MB/s maximum write performance ? No that still didn't do it for you ... well what about 200.000 IOPS (4K writes) ? Yeah that is where we have arrived in the year 2011. It's insanely fast, it will be insanely expensive but it is most definitely insanely sexy.
OCZ RevoDrive X2 240GB review
We test the OCZ Revodrive X2, a concept that is close to that IBIS product, but also is not. Will this RAID based SSD solution be faster, slower or equal in performance relative to that IBIS ? Fact remains, today we'll pass 700 MB/sec of storage performance from something slapped onto a PCIe 4x slots and that is just frightening to test, that fast.
OCZ RevoDrive 120GB review
We test and review the OCZ RevoDrive. Pretty much two SSDs slapped onto a PCB, armed with a RAID controller. Pop it in, install the new storage unit and you'll have tremendous performance right of the shelves without the need to configure anything. What OCZ did was done right. They smacked 120GB or alternatively 240 GB of the fastest NAND Flash memory on the PCB, armed that Flash memory with two separate 8-channel SandForce SSD ICs, then bind them to a SIS RAID controller, pop on a PCie x4 bridge and then offer a "PCIe SSD" (if you can call it that) reaching 300,k 400 even 500 MB/sec read and write speeds.
