SanDisk Extreme II 240GB RAID 0 SSD Report

By: Jon Coulter | RAID in Storage | Posted: Dec 5, 2013 11:03 pm

Desktop Test System




Drive Properties




The majority of our testing will be done with our test drive/array as our boot volume. Our boot volume is 75% full for all OS Disk "C" drive testing, to mimic a typical consumer OS volume implementation. We're using 64K stripes for all our arrays. Write caching is enabled.


All of our testing includes charting the performance of a single test subject as well as a RAID 0 array of our test subject. In this particular review we will be charting the performance of both a two and three drive array. We will be posting screen shots of our three drive arrays benchmarks.



ATTO Baseline Performance


Version and / or Patch Used: 2.47


ATTO is a timeless benchmark used to provide manufactures with data used for marketing storage products.




Slightly choppy performance from our two drive array but, smooth as butter performance from our three drive array.


Sequential Write




We fill our array with random 4K data and run ATTO almost immediately after. This choppy performance tends to smooth out over time after the array has had time to recover from being filled to 75% of its total capacity. Before we ran the three drive array, we waited ten minutes, and as you can see this smoothed out our arrays performance. Our three drive array easily smokes the rest of the pack.


Sequential Read




When it comes to read transfers, the Extreme II's performance is as good as it gets. Both our two drive and three drive Extreme II arrays outperform the rest of the arrays on our chart.
