ADATA Ultimate SU800 SATA III SSD Review

ATTO

 

Version and / or Patch Used: 2.47

 

ATTO is a timeless benchmark used to provide manufacturers with data used for marketing storage products. With ATTO, we are looking at maximum sequential performance with compressible data as well as the performance curve.

Sequential Write

All three capacities we are testing deliver sequential write performance that is at or above factory spec. All three deliver a nice performance curve at low queue depths. We included the Crucial BX200 as a comparison between the SMI SM2256 and SM2258 controllers. It is obvious right off the bat that the SM2258-controlled SU800's doesn't suffer the same choppy performance curve that plagues the SM2256 controlled BX200.

 

Sequential Read

The SU800's all deliver a similar performance curve to one another. The SU800's hit their stride at QD8, at lower queue depths, the SU800's are outperformed by the planar-based SSDs in our test pool. Low QD random read performance is where we would like to see better performance from Micron 3D flash. Crucial's MX300 sports the same flash array as the SU800. The SU800's display better sequential read performance than the MX300 which bodes well for SMI's SM2258 controller.

 

 

 

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 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. With Anvil's, we are focused on the total score.

Scoring

Anvil's scoring typically provides us with a good indication of a drive's overall synthetic performance. When evaluating TLC-based SSDs we are looking for a minimum score of 4,500. The 256GB and 512GB models give us what we are looking for, the 128GB model doesn't get there.

 

(Anvil) Read IOPS through Queue Depth Scale

Unlike sequential read performance, random read performance exposes a significant difference between capacity points at high queue depths. At QD1-2, the SU800 has the advantage over Crucial's MX300. At QD8 and above, the MX300 delivers better random read performance. Samsung's 750 EVO easily outperforms the rest of the drives in our test pool at all measured queue depths.

 

(Anvil) Write IOPS through Queue Scale

Low queue depth performance is what we are looking for, and this is where we find the SU800 delivering excellent performance at all three capacity points. Due to the SU800's high capacity SLC cache, there isn't much difference between capacity points.
