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 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:
Corsair V128 128GB (MLC) Indilinx
ADATA S599 100GB (MLC) SF1200
OCZ Vertex 2 100 GB (MLC) SF1200
We recently added the latest revision of the Western Digital WD1500HLFS VelociRaptor to our test suite, it is considered one of the fastest and most expensive 10k RPM HDD your money can get you. It's read/write performance is unprecedentedly good for a traditional/mechanical HDD of course.
Then the new Corsair V128 SSD, the ADATA SF1200 based S588 and finally in red, the very fast MLC based OCZ Vertex 2 nearing ~260MB/sec write performance. Look at the 4KB file size test by the way, that is unbelievably good. That's the strength of the SandForce controllers.
** Mind you that we recently updated our ATTO test suite and as such the benchmarks have all been redone, and they can differ a little here and there compared to the older reviews and test results.
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 280 MB/sec read performance when it's peaking. And again look at the tremendous increase in small file operation performance. That's more than double of Indilinx based products. I have a feeling this SSD is going to do very well in the next real-world test.
OCZ Vertex 460 SSD review We review and test the OCZ Vertex 460 SSD series released in 120 - 240 and 480 GB versions. Based on the Indilinx Barefoot 3 controller we test the 120GB NAND flash memory based model. The end result is an ...
OCZ Vertex 450 SSD review In this article we test, benchmark and review the all new OCZ Vertex 450 SSD. Armed with the new Indilinx Barefoot 3 controller this is the fifth incarnation of the popular OCZ Vertex series. Will it be as fast and competitive as it's predecessors ? Well let's see and find out shall we ?
OCZ Vertex 3.20 SSD review 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.
