Atto Disk Benchmark

One of the finest tools available to measure storage performance is ATTO. I love it to death as it is so reliable and produces such accurate results. The great thing about ATTO is that we can test with predefined block sizes. So we can test with a 32MB sequence of 4KB files, yet also 32MB in 1MB files. This gives us an excellent scope of overall performance with small and large files.

ATTO Write performance

The most important and difficult task for any storage unit is ... writing really small files fast, so let's start off there and have a look at that with this WRITE test. We scale 4KB block sizes to 1024KB block sizes in bursts of 256MB with a queue depth of 4 and then measure how fast the storage device is dealing with them. The storage units we used:

WD1500HLFS VelociRaptor in cyan
Corsair X128 (MLC) Indilinx based in green
OCZ Vertex 2 100GB (MLC) SandForce SF1200 in yellow
OCZ OCZ RevoDrive (MLC) 120GB SIS Raid / Sandforce SF1200 x2 in red

We recently added the latest revision of the Western Digital WD1500HLFS VelociRaptor to our test suite, it is considered amongst the fastest and most expensive 10k RPM HDD your money can get you. It's read/write performance is unprecedently good for a traditional/mechanical HDD of course.

Then in green an Indilix product for comparison, the Coresair X128. Then the OCZ Vertex 2 in yellow, MLC based SSD nearing ~250MB/sec write performance.

Then in red the RevoDrive takes off with near blasting performance ! Look at the test and compare it to the a traditional HDD like the Velociraptor, that is astonishingly good.

Remember, this was just the write performance !

ATTO Read performance

The previous test was write performance, but let's have a peek at read performance. The SandForce-1200 controller based SSDs kicks ass and definitely take a lead in this particular benchmark.

The SSDs are all really fast, but that's 282 MB/sec read performance when it's peaking. And again look at the tremendous increase in small file operation performance. The OCZ RevoDrive actually manages to push near 550 MB/sec when peaking.

OCZ RevoDrive Hybrid review
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.
