Version and / or Patch Used: 3.05
ATTO is a timeless benchmark used to provide manufacturers with data used for marketing storage products.
Sequential read/write transfers max out at 3422/3064 MB/s with our 512GB x 2 array. Keep in mind this is our OS volume 75% full.
Both arrays provide nearly double the sequential performance of a single drive. DMI 3.0 isn't holding back sequential write speeds.
The chipset is severely limiting sequential read speeds, which would be about 5GB/s on CPU lanes, but then our arrays wouldn't be bootable.
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 SSD's. 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.
We note about a 50% increase in scoring from a single drive to a 2 drive array, with the majority coming from increased write performance.
(Anvil) Read IOPS through Queue Depth Scale
There isn't much of a difference between the performance of a single 950 Pro and a dual 950 Pro array until after QD8. At QD16 and above, the arrays deliver better performance with both arrays topping out at about 400K IOPS. Intel's 750 AIC (Add-In-Card) is able to hit 470K IOPS. At QD1-2, the 950 Pro arrays outperform the rest of the field.
(Anvil) Write IOPS through Queue Scale
We are able to extract 170K IOPS from our dual 256GB 950 Pro array and 210K IOPS from our dual 512GB 950 Pro array. Both of these figures are about double that of a single drive. Intel's 750 AIC wins this round with a 290K IOPS performance.
