ADATA Ultimate SU800 SATA III SSD Review

Moderate Workload Model

 

We categorize these tests as indicative of a moderate workload environment.

 

PCMark Vantage - Hard Disk Tests

 

Version and / or Patch Used: 1.2.0.0

 

The reason we like PCMark Vantage is because the recorded traces are played back without system stops. What we see is the raw performance of the drive. This allows us to see a marked difference between scoring that other trace-based benchmarks do not exhibit. An example of a marked difference in scoring on the same drive would be empty vs. filled vs. steady state.

 

We run Vantage three ways. The first run is with the OS drive 75% full to simulate a lightly used OS volume filled with data to an amount we feel is common for most users. The second run is with the OS volume written into a "Steady State" utilizing SNIA's guidelines. Steady state testing simulates a drive's performance similar to that of a drive that been subjected to consumer workloads for extensive amounts of time. The third run is a Vantage HDD test with the test drive attached as an empty, lightly used secondary device.

 

OS Volume 75% Full - Lightly Used

OS Volume 75% Full - Steady State

Secondary Volume Empty - FOB

There's a big difference between an empty drive, one that's 75% full/used, and one that's in a steady state.

The important scores to pay attention to are "OS Volume Steady State" and "OS Volume 75% full." These two categories are most important because they are indicative of typical of consumer user states. When a drive is in a steady state, it means garbage collection is running at the same time it's reading/writing.

 

When tested as empty secondary volumes the SU800's outscore the competing SSDs in our test pool at all three capacity points. However, that is not what we are interested in. When testing TLC-based SSDs, we like to focus primarily on the drive's 75% full performance because we feel that those purchasing low-cost TLC SSDs will be running light to moderate bursty workloads that will not induce a steady state.

 

At 75% full, the 256GB and 512GB models deliver performance that is second to that of Samsung's powerful 750 EVO. The two larger capacity models outperform the MX300 due to their superior low queue depth random performance, which has a big influence on Vantage scoring when data is on the drive.

 

 

 

PCMark 7 - System Storage

 

Version and / or Patch Used: 1.4.0

 

We will look to Raw System Storage scoring for evaluation because it's done without system stops and, therefore, allows us to see significant scoring differences between drives.

 

OS Volume 75% Full - Lightly Used

The 256GB and 512GB models both deliver above average moderate workload performance. The 128GB model is significantly slower. However, it does perform equally to the TRION 150 which is a drive that is TweakTown recommended.

 

 

PCMark 8 - Storage Bandwidth

 

Version and / or Patch Used: 2.4.304

 

We use PCMark 8 Storage benchmark to test the performance of SSDs, HDDs, and hybrid drives with traces recorded from Adobe Creative Suite, Microsoft Office, and a selection of popular games. You can test the system drive or any other recognized storage device, including local external drives. Unlike synthetic storage tests, the PCMark 8 Storage benchmark highlights real-world performance differences between storage devices. We focus on the total storage bandwidth when evaluating PCMark 8 results.

 

OS Volume 75% Full - Lightly Used

PCMark 8 is the most intensive moderate workload simulation we run. With respect to moderate workloads, this test is what we consider to be the best indicator of a drive's overall performance. This time the MX300 gets the better of the 512GB SU800.
