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 Read performance
Have a peek at synthetically measured read performance. As you can see after 16/32KB block sizes performance jumps up significantly. That is an impressive read performance there peaking at roughly 100 MB/sec.
ATTO Write performance
The most important and difficult task for any FLASH based storage unit is writing really small files fast, our real-world perf test showed that already. But here we can exactly pinpoint the issue. Have a look at this WRITE test. We scale 4KB block sizes to 1024KB block sizes in bursts of 256MB with a queue depth of 10 and then measure how fast the storage device is dealing with them.
As you can see the S107 max out at roughly 25 MB/sec on write performance. That's quite average.
ADATA S107 Superior USB flash drive review It's time for another stick drive review here at Guru3D.com, well a USB 3.0 stick that is. The storage unit is all USB 2.0 and 3.0 compatible and it's called the S107 from ADATA's 'SUPERIOR' series of products. We test an easy to carry around 16GB version of this model. This flash drive will get you read performance of roughly 100MB/sec peaks while writing just under 25 MB/sec.
