SanDisk Ultra Plus 256GB RAID 0 SSD Report - Benchmarks - Test System Setup, Drive Properties & ATTO Baseline Performance

By: Jon Coulter | RAID in Storage | Posted: Nov 20, 2013 2:30 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.



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 erratic performance is seen here in our first test.


Sequential Write




We fill our array with random 4K data and run ATTO almost immediately after. This erratic performance tends to smooth out over time after the array has had time to recover from being filled to 75% of its total capacity.


Sequential Read




The Ultra Plus array, like most of the arrays on our chart has a temporary performance drop off at 16K transfers. The other arrays on our chart are composed of enthusiast-class and hyper-class SSD's, so it's not surprising to see our Ultra Plus array lag slightly behind in this test.
