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
- G.SKILL Falcon II 128GB (MLC)
- Corsair V128 128GB (MLC)
- ADATA S599 100 GB (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 light blue), it's read/write performance is unprecedented good for a traditional/mechanical HDD of course.
Then the G.SKILL Falcon II SSD and the new Corsair V128 SSD and finally in red the very fast MLC based ADATA S599 nearing ~260MB/sec write performance. Look at the 4KB file size test by the way, that is unbelievably good.
** 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 performance. That's more than double of the Indilinx based products.
I have a feeling this SSD is going to do very well in the next real-world test.
