ATTO

 

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 2.559 GB/s. Sequential write transfers max out at 1.279 GB/s. Our sample drive has no issues exceeding sequential specifications even as a boot volume 75% filled with data.

 

Sequential Write

Performance of our SATA arrays ramp up faster than our 750, but our 750 is able to catch them at the end of the test. Our 800GB DC P3700 with its enterprise grade flash is able to leave the rest of the drives on our chart behind at 8k transfers and higher. We are also able to see why comparing the performance of a single SATA interfaced SSD to a 750 series SSD is an unfair comparison.

 

Sequential Read

Our arrays have better small file performance than both our NVMe drives. This time the 750 hangs with our DC P3700 until we hit 1024k file transfer size. Here we can see the 750 at peak performance delivering over 4x the performance of a single SATA interfaced SSD.

 

 

Anvil Storage Utilities

 

Version and / or Patch Used: RC6

 

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.

Scoring

In this round of testing our Intel 750 flexes some muscle and defeats our 6-drive array.

 

 

Read IOPS through Queue Depth Scale

Our 750 is delivering higher performance than our SATA array at every measured point throughout the test. Our DC P3700, as expected, delivers slightly higher performance, but that performance will cost you over 3x more than a 750. All of our SATA devices plateau at QD32, but our PCIe drives have no such limitation.

 

 

Write IOPS through Queue Scale

Our arrays are delivering better performance until we hit QD4, then they take a big dive. This dive has more to do with the OS (Windows 8.1) than anything else does. The flushing policies employed by Microsoft in their most current OS's are the main cause. Windows 7 and Server 2008 have less restrictive flushing policies and this performance dive does not occur when running either of the older operating systems. Our 750 is able to outperform our DC P3700 at lower queue depths, which is an indicator that the 750 is tuned for consumer workloads.

 

 

CrystalDiskMark

 

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 QD4.

Tight competition in this test. Our arrays perform quite well. Our 6-drive array actually wins at 4k QD32. Aside from the lone win by our 6-drive array at 4K QD32, the 750 dispatches the competition (except for the DC P3700) in all other categories.

This test really plays into our arrays wheelhouse. Looking at 4k QD1, we can see that both our Intel 6-drive array and our 850 Pro array are delivering double the performance of our Intel 750. Just as we saw with Anvils IOPS testing, 4k QD4 performance is better on our arrays than our NVMe SSD's.

 

 

AS SSD

 

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.

Read performance is where the 750 really shines. It's no surprise that the 750 is faster than a 6-drive SATA array when reading data. Write performance though is another matter, and our 6-drive array puts up better performance in this test. The 750 does put up a better all-around performance as evidenced by the 750's higher score.
