Sonnet Tempo AHCI PCIe AIC 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:


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 consumer 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. This is exactly why we focus on steady state performance.


This testing, in particular, shows why we consider the nearly two-year-old SM951 AHCI SSD to still be one of the top performing SSDs on the market. If we focus on steady-state performance, we can see that the Tempo manages to win this test outright. The Tempo delivers far better 75% full and steady-state performance than the Toshiba and Intel NVMe SSDs. The Tempo is a moderate workload powerhouse.



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






Again, we see the moderate workload prowess of Samsung's SM951 AHCI SSD - only the 950 Pro delivers higher performance. The Tempo handily outperforms the Intel and Toshiba offerings.



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.


OS Volume 75% Full - Lightly Used






PCMark 8 is the most intensive moderate workload simulation we run. With respect to moderate consumer type workloads, this test is what we consider the best indicator of a drive's performance. Superior moderate workload performance is a hallmark of the Tempo. Once again, the Tempo defeats all but the 950 Pro.
