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/write transfers max out at 3605/1993 MB/s with our 400GB x 2 array. Keep in mind this is our OS volume 75% full.

 

Sequential Write

Because of RST write-back caching, the small file performance of our 750 array is greatly enhanced in comparison to a single drive. Our 750 array is able to outperform our dual 256GB 950 Pro array. Our dual 512GB 950 Pro array wins this easily, which is no surprise, considering it has a 1200 MB/s sequential write advantage.

 

Sequential Read

This chart is an excellent illustration of why you want RAID 0 and why you need to enable RST write-back caching. A properly configured array has a much-improved performance curve in comparison to a single drive when write-back caching is enabled.

 

 

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.

Scoring

We note about a 50% increase in scoring from a single drive to a two-drive array, with the majority coming from increased write performance. Our 750 array dominates the write scoring because it is able to kick out uber write IOPS. The dual 750 array is able to outscore the dual 256GB 950 Pro array, but not the dual 512GB 950 Pro array.

 

(Anvil) Read IOPS through Queue Depth Scale

The 950 Pro arrays display better performance at consumer queue depths, but the 750 array has an advantage at queue depths of 64 or greater.

 

(Anvil) Write IOPS through Queue Scale

At queue depths of two and higher, the Intel 750 series has a clear advantage over Samsung's 950 Pro. Our dual 750 array easily outperforms the rest of our test pool. Curiously, the 750 400GB AIC handily outperforms the U.2 variant.
