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, 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.
ATTO Baseline Performance
Version and / or Patch Used: 2.47
ATTO is a timeless benchmark used to provide manufacturers with data used for marketing storage products.
Our two drive array's performance ramps up quickly, with performance peaking between 32K - 256K transfers. Extremely small transfer sizes of 0.5K - 2.0K, benefit most from RAID, in comparison to a single drive, where write caching boosts performance by about 10x in comparison to a single drive.
Sequential write performance is very close to that of the 240GB 600 series array, as expected. When we compare 600 series arrays, we see the smaller capacity array's performance ramps up a little faster, and the larger capacity array has a slightly higher peak performance.
Sequential read performance again shows a different performance curve between our smaller capacity 600 series array, and the larger capacity 600 series array that we're benching today. The smaller capacity array's performance ramps up faster, but drops off at 4K transfers, where the larger capacity 600 series array has the clear advantage with transfer sizes of 8K to 64k.
