Version and / or Patch Used: 2.47
ATTO is a timeless benchmark used to provide manufacturers with data used for marketing storage products.
Sequential read transfers max out at 1.631 GB/s. Sequential write transfers max out at 1.298 GB/s. Sequential performance is, of course, limited by our chipset's bandwidth limitations. The maximum sequential read is the highest we've seen from any six-drive array to date.
Sequential write transfers max out our Lynx Point Chipset with a three-drive array.
Sequential read transfers scale very well until we hit a three-drive array, where bandwidth limitations restrict sequential throughput. We do gain performance slightly as we go from a three-drive array to four, five, and six-drive arrays. This test was run with no wait time after filling our arrays to 75% of their capacity. We did not give our four and six-drive arrays time to settle in after filling, which is why we see a faux performance drop at 16 and 32k transfer sizes.
Anvil Storage Utilities
Version and / or Patch Used: 1.1.0
Anvil's Storage Utilities is a storage benchmark designed to measure the storage performance of SSDs. The Standard Storage Benchmark performs a series of tests; you can run a full test, or just the read or write test, or you can run a single test, i.e. 4k QD16.
Read scoring is very good. Write scoring is severely limited by operating system limitations at high queue depths. We see evidence of this by the drop in performance at high queue depths.
Read IOPS through Queue Depth Scale
Read performance continues to increase as we add drives to our array, with peak performance coming at QD4.
Write IOPS through Queue Scale
Write performance does increase as we add drives to our array; however, Windows 8.1 restricts our array's IOPS from continuing to climb above QD4, and in fact causes write IOPS to fall and flatten out at QD8 - QD32. This is not the chipset, this is Windows 8.1 flushing policies.
Version and / or Patch Used: 3.0 Technical Preview
CrystalDiskMark is disk benchmark software that allows us to benchmark 4k and 4k queue depths with accuracy.
Note: Crystal Disk Mark 3.0 Technical Preview was used for these tests since it offers the ability to measure native command queuing at four and 32.
This is excellent random performance, even with Windows 8.1. This kind of random write performance is exactly why current PCIe drives are left in the dust by SATA based arrays in an OS environment.
Read performance continues to climb as we add drives to our array. The difference between a three-drive array and a six-drive array is bandwidth limited, yet we do see a pretty good increase in performance at 512k, and a very good increase as we hit 4k QD32 with our six-drive array.
Random 4k write performance is on an upward trend as we add drives to our array, with the best performance delivered at QD4.
Version and / or Patch Used: 1.7.4739.38088
AS SSD determines the performance of Solid-State Drives (SSD). The tool contains four synthetic, as well as three practice tests. The synthetic tests determine the sequential and random read and write performance of the SSD.
AS SSD reveals a nice, steady performance increase as we add drives to our array. With the last of our synthetic testing completed, let's move to our light usage model testing to give us a better idea of what's under the hood of our Extreme Pro arrays in an OS environment.
