SSD Performance Atto Disk Benchmark

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 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
• OCZ Vertex 128GB (MLC)
• Corsair X128 128GB (MLC)
• Corsair V128 128GB (MLC)

We recently added the latest revision Western Digital WD1500HLFS VelociRaptor to our test suite, it is the fastest and most expensive 10k RPM HDD your money can get you (Colored in yellow), It's read/write performance is unprecedented good.

Then in green the OCZ Vertex SSD colored in Navy Blue the Corsair X128 SSD and finally in red the very fast MLC based V128 with dead on ~200MB/sec write performance as advertised.

** Mind you that we 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 older reviews and test results.

ATTO Read performance

The previous test was write performance, but let's have a peek at read performance. All Indilinx controller based SSDs haul ass and definitely take a lead in this particular benchmark though.

The SSDs are overlapping making the results look rather unreadable, but that's roughly 267 MB/sec read performance when it's peaking, you won't hear me complaining, it puts the WD Velociraptor to an absolute shame doesn't it ?
