Intel 530 180GB Two-Drive SSD RAID Report

Version and / or Patch Used: 2.47


ATTO is a timeless benchmark used to provide manufacturers with data used for marketing storage products.




Transfers quickly ramp up, reaching full performance by 8k transfers. Read and write transfers are well balanced, strong, and consistent throughout, which is what we expect to see from a SandForce based array when the data is compressible.


Sequential Write




Write performance is second only to our EVO array.


Sequential Read




Sequential read ramps up very fast with our 530 array leading the pack at transfers up to 2k. By the end of the test, our 530 array is again running with the leaders on our chart despite being capacity handicapped. We should note that compressible data is where a SandForce based drive has no equal; however, most data comes in a compressed format, so with the exception of operating system data, this is an unrealistic portrayal of actual everyday performance you can expect from a SandForce based array.



Anvil Storage Utilities


Version and / or Patch Used: RC6


So what is Anvil Storage Utilities? First of all, it's a storage benchmark for SSDs and HDDs where you can check and monitor your performance. The Standard Storage Benchmark performs a series of tests, and you can run a full test; just the read or the write test; or you can run a single test, i.e. 4k QD16.




Incompressible data takes the legs out from under our SandForce array; that and our array's capacity handicap conspire to deliver poor performance.


Read IOPS through Queue Depth Scale




This is a clear demonstration of why the 530 is not advertised as an enthusiast class drive but rather a mainstream drive with an emphasis on reliability.


Write IOPS through Queue Scale




Keep in mind that synthetic testing, like Anvil, may not paint an accurate picture of a drive's true real-world performance. A perfect example of this is our Toshiba array that looks as if it is falling off a cliff when it is in reality one of the fastest arrays we have ever tested in a real-world scenario.





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.




We see weak performance across the board, with the exception of 4k write performance.




Incompressible read performance is mediocre. There's nothing good to report here.




Incompressible data is crippling our 530 array. It is easy to see why compressible data numbers are advertised as opposed to incompressible; however, as mentioned, this testing may not be a good indicator of our array's true performance. Look at how abysmal our Toshiba array's performance is.





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 used to determine the sequential and random read and write performance of the SSD. These tests are carried out without the use of the operating system caches.






AS SSD can really bring a SandForce array to its knees and make drives like the EVO look unbeatable. As we move to our light usage model, we will get a clearer picture of what's really under the hood.
