Intel 730 480GB 6-Drive SSD RAID Report

By: Jon Coulter | RAID in Storage | Posted: Jun 20, 2014 10:12 pm



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 1.584 GB/s. Sequential write transfers max out at 1.286 GB/s. Sequential performance is of course limited by our chipsets bandwidth limitations.


Sequential Write




Sequential write transfers max out our Lynx Point Chipset with a 4 drive array.


Sequential Read




Sequential read transfers scale very well until we hit a 4 drive array, where bandwidth limitations restrict sequential throughput. We do gain performance slightly as we go from a 4 drive array to a 5 and 6 drive array. This test was run with no wait time after filling our arrays to 75% of their capacity. We did not give our 3-6 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: RC6


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 limited severely by operating system limitations at high queue depths. You will see what I mean at the end of our testing where we run some benches on an operating that has much better storage performance than Windows 8.1


Read IOPS through Queue Depth Scale




Read performance continues to increase as we add drives to our array, typically we don't see additional performance over 4 drives, but Intel's 730K delivers the highest read IOPS of any SATA based array we've tested to date and delivers increasing performance all the way to 6 drives.


Write IOPS through Queue Scale




Write performance does increase as we add drives to our array however, Windows 8, 8.1 restricts our arrays 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 as you will see, this is the OS.





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 4 and 32.




Stunning 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 3-drive array and a 6-drive array is bandwidth limited, yet the 730K is able to squeeze in more performance, which we typically don't see from most arrays.




Random write performance is the best we've achieved to date for any SATA array.





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 are to determine the sequential and random read and write performance of the SSD.






AS SSD reveals a nice 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 730K arrays in an OS environment.
