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, in order to mimic a typical consumer OS volume implementation. We're using 64K stripes for all of our arrays. Write caching is enabled.

Our testing includes charting the performance of a single drive, as well as a RAID 0 array of our test subject/s. We are utilizing Windows 8.1 64 Bit OS for all of our testing.

Read transfers are excellent. They ramp up quickly, and stay strong throughout. However, write transfers are a different matter. Both the lack of a DRAM buffer, and our array being filled to 75% of its capacity, conspire to deliver choppy performance.

Sequential Write

Whether it's a single drive, or an array, it doesn't matter; when our test subject is loaded up with data, the write performance is choppy. When empty (FOB) there is no choppy write performance. If you FOB test, you will never encounter this performance quirk. Normally, when we see choppy performance like this, we know that the test subject is going to be brutalized by our trace based and transfer testing.

Read performance is as smooth as butter for both our single drive, and our array.
