Desktop Test System
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.
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.
Excellent scaling - two drives have double the performance of a single drive.
At very small transfer sizes of 2KB and below write caching enables our two-drive array to churn out ten times the performance of a single drive. Write performance ramps up quickly and remains steady throughout ATTO's range of transfer sizes. Maximum sequential write speed isn't as high as our Chronos Deluxe or EVO arrays.
Both our 600 array and our EVO array have a performance drop off at 16KB transfers. This performance drop off recovers at larger transfers and is probably more of a testing anomaly than anything else.
There is no dip in performance from a single drive, which is why we believe this is a testing anomaly.
